PPTC Fundamentals
PPTC Fundamentals
Introduction PPTC device and Resettable Fuse ( PTC THERMISTOR, PTC VARIABLE RESISTER, Variable Resistance PTC Thermistor, Variable Resistor, Current Limiter ) technology synergistically integrate the advance polymer material technologies, conductive material science, novel processing engineering, and fundamental electronic and electrical theory. Electrical resistance of such material and devices increases with temperature increases and vice versa. Fuzetec has successfully integrated all theses and developed a wide range of PPTC devices specifically designed to protect circuits from overcurrent. How Does PPTC Resettable Fuse Work FUZETEC™ resettable fuses are designed and made of patented novel PPTC material in thin chip form where conductive particles are dispersed in a polymer that has a crystalline structure. At normal operating conditions there are numerous chains forming conductive paths throughout the PPTC material. Under fault conditions (Tripped State), excessive current flows through the PPTC device and the PPTC material heats up. This makes the polymer matrix’s morphology change from crystalline to amorphous. Under these conditions the conductive particles move apart from each other, most of them no longer conduct current and the resistance of the device increases sharply. Upon fault current being removed, the resettable fuse is resetted and allows the current through the circuit again. PPTC Hold/Trip Current & Thermal Derating Curve IH (I Hold) defined as the maximum current the device will hold at rated temperature ( 23℃) without tripping. The probability that the PPTC will trip increases as the current approaches IT (I Trip), defined as the minimum current required to cause the PPTC device to trip at rated temperature. The range of current values between IH and IT represent a zone where performance of the device with respect to tripping can not be predicted with certainty(Fig.2, Region C). Depending on the initial resistance of the PPTC device, ambient temperature and mounting conditions, the device could either maintain a low resistance state and hold this current or it may be a sufficient current to cause the device to switch to the high resistance state.

Traditional Fuse vs. PPTC Resettable Fuse: A Comprehensive Comparison
Traditional Fuse vs. PPTC Resettable Fuse: A Comprehensive Comparison
Introduction In the realm of circuit protection, traditional fuses and PPTC (Polymeric Positive Temperature Coefficient) resettable fuses are critical components, each with its unique features and applications. Understanding the differences between these two types of fuses can significantly impact the efficiency and reliability of electronic systems. This article provides an in-depth comparison of traditional fuses and PPTC resettable fuses, highlighting their advantages, disadvantages, and ideal use cases. Understanding Traditional Fuses What is a Traditional Fuse? A traditional fuse is a simple and effective protective device used in electrical circuits. It consists of a metal wire or strip that melts when excessive current flows through it, thereby interrupting the circuit and preventing damage to the components. Traditional fuses come in various types, including glass tube fuses, blade fuses, and ceramic fuses, each suited for specific applications. How Do Traditional Fuses Work? Traditional fuses operate on a straightforward principle. When the current flowing through the fuse exceeds its rated capacity, the metal wire heats up and melts. This melting breaks the circuit, stopping the current flow and protecting the rest of the circuit from damage. Once a traditional fuse has blown, it must be replaced with a new one to restore the circuit's functionality. Advantages of Traditional Fuses Simplicity: Traditional fuses are straightforward in design and easy to install. Cost-Effective: They are generally inexpensive and widely available. Reliability: They provide reliable protection by completely disconnecting the circuit during an overcurrent event. Disadvantages of Traditional Fuses Non-Resettable: Once blown, traditional fuses must be replaced, which can be inconvenient and costly over time. Limited Flexibility: They do not offer adjustable protection levels and are specific to their rated capacity. Interruption Time: The time it takes for a traditional fuse to blow can vary, potentially allowing some damage to occur before the circuit is interrupted. Understanding PPTC Resettable Fuses What is a PPTC Resettable Fuse? PPTC resettable fuses are advanced circuit protection devices that offer the unique ability to reset themselves after an overcurrent event. These fuses are made from a polymer material with conductive particles embedded within. When the current exceeds the fuse's rated capacity, the polymer heats up, causing the conductive particles to separate and the resistance to increase dramatically, thereby limiting the current flow. How Do PPTC Resettable Fuses Work? When an overcurrent event occurs, the PPTC material heats up, increasing its resistance and effectively reducing the current to a safe level. Once the fault condition is cleared and the device cools down, the PPTC material returns to its original low-resistance state, allowing normal current flow to resume. This self-resetting feature makes PPTC fuses particularly useful in applications where manual replacement of fuses is impractical. Advantages of PPTC Resettable Fuses Self-Resetting: They automatically reset after the fault condition is cleared, eliminating the need for manual replacement. Versatile Protection: PPTC fuses can handle multiple overcurrent events without needing replacement. Maintenance-Free: They reduce maintenance costs and downtime associated with fuse replacement.

PPTC Resettable Fuses PPTC resettable fuses limit the current flow during an overcurrent event without completely disconnecting the circuit. This allows for continued, albeit limited, operation of the circuit, which can be beneficial in some applications. Cost Considerations Initial Cost Traditional fuses generally have a lower initial cost compared to PPTC resettable fuses. This makes them attractive for applications with tight budget constraints. Long-Term Cost PPTC resettable fuses, despite their higher initial cost, can offer long-term savings by reducing the need for maintenance and replacement. In environments where frequent overcurrent events occur, the ability of PPTC fuses to reset themselves can result in significant cost savings over time. Conclusion Both traditional fuses and PPTC resettable fuses play vital roles in circuit protection, each with its unique strengths and weaknesses. Traditional fuses offer simplicity, reliability, and cost-effectiveness, making them suitable for a wide range of applications. On the other hand, PPTC resettable fuses provide self-resetting capabilities, versatile protection, and reduced maintenance, ideal for applications where manual replacement of fuses is impractical. Choosing the right type of fuse depends on the specific requirements of the application, including factors such as cost, maintenance, accessibility, and the nature of the overcurrent events.

Understanding TVS Diodes and MOV Varistors for Transient Surge Protection
Understanding TVS Diodes and MOV Varistors for Transient Surge Protection
Introduction In today's electronic world, transient surge protection is crucial to ensuring the longevity and reliability of electronic devices. Transient surges, caused by events such as lightning strikes, power switching, and electrostatic discharge (ESD), can lead to significant damage to sensitive electronic components. As a field application engineer specializing in circuit protection components, I aim to provide an in-depth understanding of two critical components used for transient surge protection: TVS diodes and MOV varistors. What are TVS Diodes? TVS Diodes: Definition and Functionality Transient Voltage Suppression (TVS) diodes are specialized semiconductor devices designed to protect electronic circuits from transient voltage spikes. TVS diodes are designed to clamp overvoltages to a safe level, protecting sensitive components from damage. These devices are characterized by their fast response time and precise clamping voltage. How TVS Diodes Work When a transient voltage exceeds the breakdown voltage of the TVS diode, the diode becomes conductive, allowing the excess current to pass through the diode and away from the protected components. This action effectively clamps the voltage to a safe level, preventing damage to the circuit. Once the transient event subsides, the TVS diode returns to its non-conductive state, ready to protect against future surges. Applications of TVS Diodes TVS diodes are widely used in various applications, including: Telecommunication Devices: Protecting against lightning-induced surges. Automotive Electronics: Ensuring the reliability of electronic control units (ECUs) and sensors. Consumer Electronics: Safeguarding devices such as smartphones and laptops from ESD and power surges. Industrial Equipment: Providing protection in harsh environments with high transient surge potential. Fuzetec TVS Diodes Products What are MOV Varistors? MOV Varistors: Definition and Functionality Metal Oxide Varistors (MOVs) are voltage-dependent resistors that provide transient surge protection by changing their resistance with respect to the applied voltage. MOVs are composed of zinc oxide particles and other metal oxides, creating a ceramic-like material that exhibits non-linear resistance characteristics. How MOV Varistors Work Under normal operating conditions, MOVs exhibit high resistance, allowing minimal current to flow through them. When a transient surge occurs, the voltage across the MOV increases, causing its resistance to drop significantly. This low resistance path allows the excess surge current to flow through the MOV, diverting it away from the protected components. After the surge event, the MOV returns to its high resistance state, ready to protect against future surges. Applications of MOV Varistors MOV varistors are commonly used in applications such as: Power Supplies: Protecting against overvoltage conditions. Home Appliances: Safeguarding electronics from lightning strikes and power surges. Communication Systems: Providing transient protection for signal lines. Industrial Controls: Ensuring the reliability of control systems in the presence of surges. Fuzetec MOV Varistor Products Comparing TVS Diodes and MOV Varistors Response Time One of the critical differences between TVS diodes and MOV varistors is their response time. TVS diodes are known for their fast response time, typically in the order of picoseconds to nanoseconds, making them ideal for protecting high-speed data lines and sensitive electronic circuits. In contrast, MOV varistors have a slower response time, typically in the order of microseconds, which can be sufficient for many power line and general surge protection applications. Clamping Voltage Precision TVS diodes offer precise clamping voltage, providing tight protection thresholds, which is essential for protecting low voltage and sensitive circuits. On the other hand, MOV varistors have a wider clamping voltage range, which can be advantageous in applications where exact clamping is not as critical but where higher energy handling is required. Energy Absorption Capability MOV varistors generally have a higher energy absorption capability compared to TVS diodes. This characteristic makes MOVs suitable for applications where large surge energy needs to be dissipated, such as in AC power lines and heavy-duty industrial equipment. TVS diodes, while having lower energy absorption capacity, are better suited for protecting smaller, more sensitive components. Longevity and Durability TVS diodes typically have a longer lifespan and better durability under repeated transient events compared to MOV varistors. MOVs can degrade over time with repeated surges, leading to a decrease in their protective capability. This degradation is less of an issue with TVS diodes, making them a more reliable choice for applications with frequent transient occurrences. Selecting the Right Protection Component Factors to Consider When selecting between TVS diodes and MOV varistors for transient surge protection, several factors should be considered: Nature of the Transient Events: High-speed and low-energy transients may be better managed by TVS diodes, while high-energy surges are more suitable for MOV varistors. Clamping Voltage Requirements: For precise clamping, TVS diodes are preferable. For broader clamping ranges, MOV varistors are more suitable. Energy Handling Needs: Applications requiring high energy absorption should consider MOV varistors. Longevity and Durability: For applications with frequent surges, TVS diodes offer better long-term reliability. Application Examples Consumer Electronics: Use TVS diodes for protecting USB ports, HDMI interfaces, and other sensitive data lines. Industrial Power Supplies: Employ MOV varistors for protecting AC power lines and heavy-duty equipment. Automotive Systems: Combine TVS diodes for protecting low voltage circuits and MOV varistors for high-energy protection on power lines. Conclusion Both TVS diodes and MOV varistors play crucial roles in transient surge protection, each offering unique advantages suited to different applications. Understanding the specific requirements of your application is essential in selecting the appropriate protection component. Whether you need the fast response and precise clamping of a TVS diode or the high energy absorption capability of an MOV varistor, these components provide reliable protection to ensure the longevity and reliability of your electronic devices.

This article explores the essential protection mechanisms for Li-ion and Li-Polymer batteries, highlighting solutions offered by Fuzetec to safeguard against common faults such as short circuits and overcharging. The Necessity of Battery Protection Vulnerabilities of Li-Ion Batteries Li-ion batteries are susceptible to various faults that can compromise their integrity and safety. These include external shorts, runaway charging conditions, and abusive overcharging, all of which can lead to hazardous overcurrent and overtemperature situations. Overcharge, deep-discharge, or short circuit conditions can generate excessive heat, causing the battery cell to bloat, rupture, or even ignite. Internal cell failures, while less common, can also affect the complex electronics on the battery pack’s Protection Circuit Module (PCM), such as the fuel gauge or charge controller. Consequently, multiple levels of protection against overcharge, over-discharge, overtemperature, and overvoltage conditions are essential to prevent thermal runaway and potential failure. Regulatory Compliance Safety regulations and test requirements from organizations like UL, IEC, and IEEE are in place to ensure the resilience of Li-ion and Li-Polymer battery packs against short circuits and overcharge events. Standards such as UL2054, IEEE 1725-2011, and IEC 62133 provide guidelines to demonstrate battery safety in various applications. Protection Strategies Short Circuit Conditions Unprotected battery cells can deliver extremely high currents when subjected to a short circuit, leading to significant temperature rises. This can result in thermal runaway, causing severe damage or fire. Accidental short circuits, such as those caused by metal objects bridging exposed terminals, further underline the need for robust protection mechanisms. Overcharge Conditions Proper charging profiles are critical to optimize battery performance and safety. Overcharge conditions, typically resulting from charger faults or the use of incompatible chargers, can cause significant temperature increases, leading to chemical degradation of the cell components. Overcurrent or overvoltage conditions exacerbate this issue, emphasizing the need for precise protection solutions. Advanced Protection Solutions by Fuzetec PPTC Resettable Fuses Fuzetec's PPTC (Polymeric Positive Temperature Coefficient) resettable fuses provide an effective solution for both short circuit and overcharge protection. These devices rapidly increase in resistance when exposed to excess current, limiting the fault current and preventing thermal runaway. Once the fault is cleared and power is cycled, the device returns to its low-resistance state. PPTC resettable fuses offer significant advantages over traditional bimetal or thermal fuse protectors, including lower cost, reduced bulk, and improved reliability. Unlike one-shot fuses, PPTC devices reset themselves, avoiding unnecessary field returns due to non-resettable protection devices. Implementation of PPTC Devices Strap Products PPTC strap products, including the FVL, FVT, FSR, and FLR families, are designed for various battery chemistries and usage profiles. These devices can be spot welded to battery cells or straps, providing a space-saving solution for cylindrical, prismatic, and pouch packs. Fuzetec Strap Series Operation Current: FVL Series 1.7A~2.3A ; FVT Series 1.1A~2.4A FLR Series 1.9A~7.3A ; FSR Series 1.2A~4.2A Maximum Voltage: 12V ~ 30VDC Rechargeable Battery Packs, Lithium Cell and Battery Packs Surface-Mount Products Fuzetec’s surface-mount products, available in standard 1206 and 1210 packages, are well-suited for battery PCMs. These devices save board space and ease design complexity, offering low resistance to maintain system impedance budgets. Fuzetec FSMD 1210 series Operation Current:0.05A ~2.00A VMAX:6VDC~60VDC IMAX: 100A. All High-Density Board Fuzetec FSMD 1206 Series Operation Current:0.05A ~2.00A VMAX: 6VDC~60VDC, IMAX: 100A. All High-Density Board Disc Products PPTC disc devices, made of PPTC material, are placed inside Lithium-ion 18650 cylindrical cell headers to protect cells during shipping and handling. These custom-designed devices also provide protection for individual cells sold for consumer use. Selecting the Right Protection Devices Choosing the appropriate protection devices for a specific application involves understanding the protection requirements based on cell chemistry and application conditions. System tests should be conducted to determine the suitability of a protection device, with recommendations from device manufacturers serving as a starting point for further investigation. Conclusion As portable electronics continue to evolve towards thinner and more compact designs, the need for reliable and efficient battery protection becomes increasingly critical. Fuzetec offers a comprehensive range of PPTC resettable fuses, MHP-TA thermal cutoff devices, and other innovative solutions to meet the diverse protection needs of modern Li-ion and Li-Polymer battery packs. By integrating these advanced protection devices, designers can ensure the safety, reliability, and longevity of their battery-powered products.
