TPSMC9.1HE3_A/H 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. Are TVS diodes and Zener diodes the same?

    TVS diodes and Zener diodes have significant differences in functionality and characteristics, so they are not identical.
    Definition and purpose
    Zener diode: Zener diode is a diode that uses a PN junction for reverse breakdown. It is mainly used to ensure voltage stability. It has a high resistance state before the reverse breakdown voltage and is in a low resistance state after exceeding this critical point. It is widely used in various voltage stabilizing circuits and reference voltage components.
    TVS Diode: TVS diode (Transient Suppression Diode) has surge absorption capability and is mainly used to protect circuits from damage caused by transient high voltages such as surges and electrostatic discharge (ESD). It can absorb a large amount of instantaneous current and voltage in a short period of time, protecting the subsequent equipment or circuits from damage.

  • 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.
