TPSMC9.1HE3_A/I 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. TVS is the abbreviation of diode. What does it mean?

    TVS is the abbreviation of Transient Voltage Suppressor, also known as Transient Voltage Suppression Diode.
    How TVS diodes work
    TVS diodes work using the avalanche breakdown effect. When the TVS diode receives a reverse voltage, the depletion layer near its PN junction will increase, causing the electric field intensity to increase, which in turn triggers the avalanche effect and causes the reverse current to increase sharply. Unlike ordinary diodes, TVS diodes can recover after avalanche breakdown and continue to work normally.

  • 3. What is the difference between TVS diodes and MOVs?

    The main differences between TVS diodes and MOV varistors lie in their working principles, application scenarios and performance parameters.
    Working principle
    TVS diode: TVS diode (Transient Voltage Suppressor) is a semiconductor device with a high-sensitivity N/P junction. When the reverse voltage exceeds its breakdown voltage, the TVS diode will conduct quickly and introduce the surge current into the ground, thereby protecting the subsequent circuit. The response speed of TVS diodes is very fast, usually within nanoseconds.
    MOV varistor: MOV varistor (Metal-Oxide Varistor) is a multi-layer varistor made of multi-layer zinc oxide material. When the voltage exceeds its varistor voltage, the MOV will conduct, absorb the surge energy, and clamp the voltage within a safe range. MOV has a long response time, usually completing the response within microseconds.
