DF3A5.6LFU,LF 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 is the difference between TVS and ordinary diodes?

    The main difference between TVS diodes and ordinary diodes lies in their working principle, application scenarios and characteristics.
    Working principle and application scenarios
    TVS diode: TVS diode (Transil Voltage Suppressor) is a high-efficiency protection device that stabilizes and suppresses overvoltage based on the breakdown effect of PN junction. When the voltage exceeds its breakdown voltage, the TVS diode will conduct quickly and release the overvoltage to ground, thus protecting the precision components in the circuit from damage by surge pulses. TVS diodes are widely used in computer systems, communication equipment, automotive electronics, household appliances and other fields to suppress transient overvoltage and electromagnetic interference.
    Ordinary Diode: The main function of an ordinary diode is unidirectional conductivity, allowing current to pass in one direction and blocking reverse current. They are widely used in rectification, signal modulation, power management and other scenarios.
    Feature comparison
    Current size: The Zener breakdown current of TVS diodes is small, usually around 1mA, while the breakdown current of ordinary diodes is larger.
    Classification: TVS diodes are divided into unipolar and bipolar according to polarity; ordinary diodes are divided into low-voltage and high-voltage types according to the level of voltage regulation, as well as N-type and P-type materials.
    Voltage regulation characteristics‌: The voltage characteristics of TVS diodes are nonlinear, the resistance before breakdown is high, and the voltage remains constant after breakdown; the voltage of ordinary diodes remains constant at the critical reverse breakdown point, realizing the voltage stabilization function.

  • 2. 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.

  • 3. How fast are TVS diodes?

    TVS diodes are very fast and can respond within 10^-12 seconds (i.e. 1 nanosecond). When the two poles of the TVS diode are impacted by reverse transient high energy, it can change the high impedance between its two poles into low impedance in a very short time, while absorbing surge power up to several kilowatts, reducing the voltage between the two poles. It is clamped to a predetermined safe value, thereby effectively protecting precision components in electronic circuits from damage by various surge pulses.
    This fast response characteristic of TVS diodes allows them to play an important role in various electronic systems, especially where precision electronic components need to be protected from transient voltage impacts. For example, in the fields of computer systems, communication equipment, automotive electronics, household appliances, etc., TVS diodes are widely used to protect circuits from electrostatic discharge, surge voltage, and electromagnetic interference.
