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 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.

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.
