20S Series Special-Shaped Varistor, Practical Zinc Oxide Lightning Protection Varistor
The varistor is a voltage limiting protection device. Utilizing the nonlinear characteristics of the varistor, when an overvoltage occurs between the two poles of the varistor, the varistor can clamp the voltage to a relatively fixed voltage value, thereby realizing the protection of the subsequent circuit. The main parameters of varistors are: varistor voltage, flow capacity, junction capacitance, response time, etc.
The response time of the varistor is ns level, which is faster than the gas discharge tube and slightly slower than the TVS tube. Generally, it is used for the overvoltage protection of electronic circuits and its response speed can meet the requirements. The junction capacitance of varistors is generally on the order of hundreds to thousands of Pf. In many cases, it is not suitable to be directly applied to the protection of high-frequency signal lines. When it is used in the protection of AC circuits, because its large junction capacitance will increase the leakage Current needs to be fully considered when designing the protection circuit. The flow capacity of the varistor is larger, but smaller than that of the gas discharge tube. The varistor, referred to as MOV, is a voltage-sensitive non-linear overvoltage protection semiconductor component.

Application
1. Varistor voltage: refers to the voltage value across the varistor at a specified temperature and DC (generally 1mA or 0.1mA). Recorded as V1mA or V0.1mAo
2. Maximum continuous voltage: refers to the maximum effective value of sinusoidal AC voltage or the maximum DC voltage value that can be continuously applied to both ends of the varistor for a long time under the specified ambient temperature
3. Limiting voltage: refers to the maximum peak voltage at both ends of the varistor when a specified surge current (8,20μs) passes through it.
4. Rated power: refers to the maximum average impact power that can be applied to the varistor under the specified ambient temperature.
5. Maximum energy: the maximum impact energy that can be applied to the varistor under the condition that the varistor voltage does not change more than ±10% and the impulse current waveform is 10, 1000μs or 2ms.
