CM1205-08CP Classification

TVS - Diodes

TVS - Diodes are electronic components designed to protect circuits from transient overvoltage damage. They protect other sensitive components in the circuit from damage by quickly switching on and directing excess transient voltage to ground or power supply. TVS diodes are typically constructed of PN junction or metal oxide semiconductor structures with extremely fast response times and low clamping voltage characteristics. Its design principle is based on the avalanche breakdown effect, that is, when a specific voltage threshold is reached, the diode will rapidly change from a high resistance state to a low resistance state, limiting the transient voltage to a safe level. TVS diodes are used in a wide variety of electronic devices, especially those that need to protect critical circuits from lightning strikes, electrostatic discharges, or other transient voltage events.

FAQ about TVS - Diodes

  • 1. What does a TVS diode do?

    The main function of TVS diodes (Transient Voltage Suppression Diodes) is to protect electronic equipment from voltage spikes and surge voltages‌. When the two poles of the TVS diode are impacted by reverse transient high energy, it can change the high impedance between the two poles into low impedance within 10^-12 seconds, while absorbing surge power up to several kilowatts, causing the gap between the two poles to The voltage is clamped to a safe value, thereby effectively protecting precision components in electronic circuits.
    The specific working principle of TVS diodes is as follows:
    Absorb surge power‌: TVS diodes can, under reverse application conditions, when subjected to a high-energy large pulse, their working impedance immediately drops to a lower conduction state, allowing large current to pass while clamping the voltage at predetermined level. Its response time is only 10^-12 seconds.
    Protection circuit: TVS diodes are used in parallel with the protected circuit. When the circuit is working normally, the TVS diode is in a high impedance state and does not affect the circuit; when there is a surge voltage impact, the TVS diode conducts quickly, absorbs the surge energy, and protects the subsequent circuit.


  • 2. What is the difference between TVS and ESD diodes?

    The main difference between TVS diodes and ESD diodes is their working principle, application scenarios and characteristics.
    Working principle and application scenarios
    TVS diodes (Transient Voltage Suppressors): TVS diodes are mainly used to suppress transient voltages and prevent components in the circuit from being damaged by surge voltages. When the two poles of the TVS diode are impacted by reverse transient high energy, it can change the high impedance to low impedance in a very short time, absorb the surge power, and protect the precision components in the circuit‌1. TVS diodes are suitable for protection against various surge pulses, such as lightning strikes, large-capacity load switching, etc.
    ESD diode (Electro-Static discharge): ESD diode is mainly used to prevent static electricity and prevent damage to electronic equipment caused by electrostatic discharge. ESD diodes have low capacitance values, typically between 1 and 3.5 picofarad (PF), to accommodate the rapid changes in electrostatic discharge. ESD diodes are suitable for board-level protection, especially in high-speed USB and I/O interfaces, which have higher requirements for electrostatic discharge.

  • 3. How do TVS diodes fail?

    The failure modes of TVS diodes mainly include short circuit failure, open circuit failure and performance degradation‌. These failure modes can have a serious impact on the normal operation and protection functions of the circuit.
    short circuit fault
    Short circuit failure is one of the most common failure modes of TVS diodes. When a TVS diode is short-circuited, it changes to a low-impedance state, allowing a large amount of current to pass through, which may cause the circuit to not function properly and may even damage other circuit components. Causes of short circuit faults include:
    Thermal breakdown: In a high temperature environment or when subjected to excessive transient energy impact, the PN junction of the TVS diode may undergo thermal breakdown, resulting in a short circuit.
    Over-electrical stress: When the transient pulse energy exceeds the energy that the TVS can withstand, it will cause over-electrical stress damage and even directly cause burnout.
    Manufacturing process issues: Such as chip bonding interface voids, mesa defects, strong accumulation layer or strong inversion layer on the surface, chip cracks, uneven impurity diffusion, etc., which may cause short circuit failures of TVS diodes during manufacturing or use.
