What is TSS semiconductor discharge? What are its main applications?

TSS semiconductor discharge tube (Transient Suppressing Semiconductor), also known as TVS semiconductor discharge tube, is a passive electronic component used to protect electronic devices. It can limit the amplitude and slope of transient voltage, thereby protecting other components in the circuit from voltage transients. The following are the working principles and applications of TSS semiconductor discharge tubes:

1. Working Principle

The working principle of TSS semiconductor discharge tubes is based on the Zener effect and Avalanche effect of semiconductor materials such as germanium and silicon. When there is a voltage transient in the circuit, causing the voltage value to exceed a set threshold, the TSS semiconductor discharge tube will exhibit the Zener effect or Avalanche effect, forming a low-impedance path to ground or other locations, thus protecting the stability and safety of the circuit from voltage transients.

2. Applications

TSS semiconductor discharge tubes are widely used in various electronic devices, including computers, communication equipment, consumer electronics, automotive electronics, etc. The following are specific applications:(1) Power Line Protection: TSS semiconductor discharge tubes can be used to protect power lines from sudden electromagnetic interference (EMI) and power transients.(2) Communication Line Protection: TSS semiconductor discharge tubes can be used to protect communication lines from electrostatic discharge (ESD) and power transients.(3) Sensor Protection: TSS semiconductor discharge tubes can be used to protect sensors and measuring devices from electrostatic discharge and surge voltage.(4) LED Protection: TSS semiconductor discharge tubes can be used to protect LED lights from electrostatic discharge and transient voltage.(5) Automotive Electronics Protection: TSS semiconductor discharge tubes can be used to protect automotive electronic systems from electrostatic discharge, lightning, and surge voltage.(6) Medical Electronic Equipment Protection: TSS semiconductor discharge tubes can be used to protect medical electronic equipment from electrostatic discharge and power transients.In summary, TSS semiconductor discharge tubes are reliable electronic components that can protect circuits from voltage transients, enhancing the stability and safety of products.
