Popular Science Knowledge on Transient Suppression (TVS) Diodes

TVS diode is an essential and efficient protective component that plays an important role in electronic products and equipment, with indelible achievements. Can transient suppression (TVS) diodes be replaced by ordinary diodes in practical applications? Before answering this question, let's first have a thorough understanding of the popular science knowledge related to transient suppression (TVS) diodes!

Diode TVSS is a type of anti surge overvoltage protection device, invented on the basis of voltage regulator diodes. It is a new and efficient circuit protection device specifically designed to suppress transient overvoltage and has superior overvoltage and surge protection effects. When the circuit works normally, the transient diode is in a High impedance state, which will not affect the normal operation of the circuit; When an abnormal surge or voltage occurs in the circuit and reaches the breakdown voltage of the transient diode, the transient diode quickly changes from a High impedance to a low resistance state, absorbs an instantaneous overcurrent, clamps the abnormal overvoltage Voltage clamp at a lower level, and protects the precision components of the subsequent circuit from the impact and damage of the transient high-voltage spike pulse.

There are many types of ordinary diodes, and different diodes have different functions and application environments. A voltage regulator diode is a phenomenon that utilizes the reverse breakdown state of the PN junction, where the current can vary over a large range while the voltage remains basically unchanged. It serves as a voltage regulator in the manufacturing process. Rectifier diode is a semiconductor device used to convert alternating current into direct current, with high breakdown voltage, low reverse leakage current, and good high-temperature performance. It is mainly used in various power supply rectifier circuits. According to the definition, transient diodes cannot be replaced by ordinary diodes such as rectifier diodes and voltage regulator diodes. To replace the part number, you can find TVS diode models with the same or similar parameters, or switch brands and suppliers!
