The working principle and application of TVS transient suppression diode

TVS diode (transient voltage suppressor diode)

It is a protective circuit commonly used to prevent sudden voltage increases or reverse voltage from affecting the circuit. As a voltage regulation and protection component, it can stabilize voltage and convert excess voltage into heat or electrical energy for dissipation. TVS diodes feature high reverse voltage, fast response speed, and high endurance for repeated operations, making them widely used in lightning protection, surge damage prevention, and other applications.

TVS diodes (triacs) are commonly used in the following scenarios:

1. Protect power supply equipment such as power stabilizers and switching power supplies from surge voltage and overvoltage in power lines;
2. Protect electronic devices such as computers and communication equipment from overvoltage, electromagnetic pulse, electrostatic discharge, and other phenomena caused by grid fluctuations;
3. Used to protect LED lighting, automotive lighting, and other equipment from electrical damage or malfunctions caused by abnormal operating conditions due to high voltage excitation from specific circuits;
4.  Used to prevent high voltage generated by charging issues in lightning protection grounding wires, antenna leads, and other similar equipment;
5. TVS diodes are also frequently used in automotive electrical systems to protect electrical equipment and components from voltage surges and peak voltages generated by inductive power generation.

In summary, TVS diodes are widely used in many fields, including power systems, communications, industrial control, automotive, consumer electronics, and more.
