*FAQ:
Q: What is the role of the varistor in the circuit?
A: The resistor body material of the varistor is a semiconductor, so it is also a kind of semiconductor resistor. Zinc oxide varistor is commonly used in recent years.
The varistor has three main functions: overvoltage protection, lightning resistance and used for safety test.
A varistor is not pressure sensitive, but a voltage sensor. It is a bit like a fuse. If the voltage exceeds its withstand voltage, it will break down and protect the circuit.
The varistor is usually used together with fuse for lightning strike or other overvoltage protection.
