This article explores the working principle of TVS diodes and their wide range of applications in fields such as overvoltage protection, ESD protection, and lightning surge protection, revealing their significant value as core components for circuit protection.

How does TVS protect circuits from transient overvoltage impacts?

Working Principle: The TVS diode utilizes the avalanche breakdown characteristic of the p-n junction under reverse bias. When the voltage exceeds the breakdown voltage of the TVS diode, it enters a conductive state and diverts the current to the ground line. This action clamps the transient overvoltage to a safe level, protecting sensitive electronic components. In summary, the TVS diode can clamp transient overvoltage to a safe level within an extremely short time, providing effective protection for electronic circuits. Its fast response and high energy absorption capability make it an ideal choice for overvoltage protection.

Besides overvoltage protection, what other uses do TVS diodes have? Can they be used as interference suppression components in noise suppression circuits?

TVS (Transient Voltage Suppressor) diodes have several other applications besides overvoltage protection and can indeed be used as interference suppression components in noise suppression circuits. Here are several main applications and functions of TVS diodes:

Anti-Electrostatic Discharge (ESD): TVS diodes can effectively absorb high-voltage transient pulses caused by electrostatic discharge, protecting sensitive electronic components from damage. This makes them widely used in computers, communication equipment, consumer electronics, and other fields.

Lightning Strike Protection: In power and signal lines, TVS diodes can be used to prevent transient overvoltage caused by lightning strikes, protecting equipment from damage. This is particularly important for outdoor equipment and communication base stations.
