Popular knowledge about transient suppression (TVS) diodes

TVS diode is an indispensable high-efficiency protection component. It plays an important role in electronic products and equipment and has indelible achievements. So in practical application, can TVs diodes be replaced by ordinary diodes? Before answering this question, let's have a good understanding of the popular science related to transient suppression (TVS) diodes!

Diode TVs is a kind of anti surge overvoltage protection device. It is invented on the basis of Zener diode. It is a new and efficient circuit protection device, which is specially used to suppress transient overvoltage and has superior overvoltage anti surge protection. When the circuit works normally, the transient diode is in a high resistance state, which will not affect the normal operation of the circuit; When the circuit has abnormal surge or voltage and reaches the transient diode breakdown voltage, the transient diode quickly changes from high resistance state to low resistance state, instantly absorbs an instantaneous overcurrent, clamps the abnormal overvoltage at a lower level, and protects the precision devices of the subsequent circuit from the impact and damage of the transient high-voltage spike pulse.

There are many kinds of ordinary diodes. Different diodes have different functions and application environments. Zener diode is a kind of diode that can stabilize voltage by using the reverse breakdown state of PN junction, whose current can change in a large range and the voltage is basically unchanged. Rectifier diode is a semiconductor device used to convert alternating current into direct current. It has high breakdown voltage, low reverse leakage current and good high temperature performance. It is mainly used in various power rectifier circuits. According to the definition, transient diodes cannot be replaced by ordinary diodes such as rectifier diodes and voltage stabilizing diodes. If you want to replace the material number, you can find TVS Diode models with the same or similar parameters, or change the brand supplier!
