About Varistor

The varistor is a kind of voltage limiting protective device. Using the nonlinear characteristic of the varistor, when the overvoltage appears between the two poles of the varistor, the varistor can clamp the voltage to a relatively fixed voltage value, so as to realize the protection of the back stage circuit. The main parameters of the varistor are: varistor voltage, flow capacity, junction capacitance, response time, etc.

The response time of the varistor is NS class, which is faster than the gas discharge tube and slightly slower than TVS tube. Generally, the response speed of the over-voltage protection used for electronic circuits can meet the requirements. The junction capacitance of varistors generally ranges from hundreds to thousands of Pf. In many cases, it is not suitable to be directly used in the protection of high-frequency signal lines and ac circuit, because the junction capacitance will increase the leakage current, which needs to be fully considered in the design of the protection circuit. The flow capacity of the varistor is larger, but smaller than that of the gas discharge tube. Voltage sensitive resistor (VDR) is a kind of nonlinear over-voltage protection semiconductor device sensitive to voltage.

(1) Distinguish voltage sensitive resistors for power protection from those for signal line and data line protection, and they should meet the requirements of different technical standards.

(2) According to the different continuous working voltage applied on the varistors, the varistors used across the power line can be divided into two types: AC or DC. The aging characteristics of the varistors under these two volt-age stresses are different.

(3) According to the dffrent characteristics of abnormal overvoltage borne by the varistors, the varistors can be divided into three types. surge suppression type, high power type and high energy type.
