What is a varistor?
A varistor is a resistor whose resistance value changes with voltage within a certain current and voltage range, or a resistor whose "resistance value is sensitive to voltage"， abbreviated as VDR". The resistor body material of the varistor is a semiconductor, so it is a type of semiconductor resistor. Now the most widely used varistors are "zinc oxide" (ZnO) varistors
How to choose a varistor?
1)The voltage value of the varistor should be greater than the voltage peak value in the actual circuit, that is, the power supply voltage continuously applied to both ends of the varistor should be less than the "maximum continuous working voltage value" in the varistor specification.
2)The clamping voltage of the varistor should be less than the maximum voltage of the protected equipment.
3)The nominal discharge current of the varistor should be greater than the maximum surge current that may appear in the line.
4) Consider the use environment and the specific requirements of the surge voltage.
