It is a metal oxide semiconductor non-linear resistance with ZnO as the main component. When the voltage applied to its two ends reaches a certain value, the resistance is very sensitive to voltage. Its working principle is equivalent to the series-parallel connection of multiple semiconductor P-Ns. Varistors are characterized by good non-linear characteristics (I=non-linear coefficient α in CUα), large current capacity (～2KA/cm2), low normal leakage current (10-7～10-6A), and low residual voltage (depending on the Due to the working voltage and current capacity of the varistor, the response time to instantaneous overvoltage is fast (~10-8s), and there is no freewheeling.
The technical parameters of varistors mainly include: varistor voltage (ie switching voltage) UN, reference voltage Ulma; residual voltage Ures; residual voltage ratio K (K=Ures/UN); maximum flow capacity Imax; leakage current; response time .
The use conditions of the varistor are: varistor voltage: UN≥[(√2×1.2)/0.7] U0 (U0 is the rated voltage of the industrial frequency power supply)
Minimum reference voltage: Ulma≥(1.8～2) Uac (used under DC conditions)
