TGE metal oxide varistor symbol resistive material is a semiconductor, so it is a variety of semiconductor resistor. "Zinc oxide" Now a lot of use of (ZnO) varistor, it has two main material
Price element (Zn) and hexavalent elemental oxygen (O) of the composition. So from the point of view of materials, the zinc oxide metal oxide varistor basics is a "Ⅱ-Ⅵ family-oxide semiconductor."
Varistor protection, the vast majority of applications, it can repeatedly effect, but sometimes also to make it into the current fuse as a "one-off" protection device. For example, and then
On some of the short-circuit current transformer load contacts varistors. The most important feature of the TGE varistor metal oxide is added on top of it when voltage drops below its threshold "UN" when the current flowing through it is extremely small, phase
When in a shut valve, when the voltage exceeds the UN, the surge current flowing through it, is equivalent to the valve open. Using this feature, you can suppress the circuit often appear abnormal over-voltage protection
Protect circuitry from overvoltage damage.

What varistor is it?
Refers to the resistance value of the TGE metal oxide varistor symbol voltage-sensitive resistor, that is, within a certain range of the resistance value of current and voltage with the voltage change.
Varistor resistive material is a semiconductor, so it is a variety of semiconductor resistor. "Zinc oxide" Now a lot of use of (ZnO) high voltage varistor, it has two main material
Price element (Zn) and hexavalent elemental oxygen (O) of the composition. So from the point of view of materials, the zinc oxide varistor is a "Ⅱ-Ⅵ family-oxide semiconductor."
Varistors useful? "Safety valve" effect TGE varistor metal oxide circuit, its greatest feature is added on top of it when the voltage is below its threshold "UN" when the current flowing through it is extremely small, the equivalent of
A shut the valve, when the voltage exceeds UN, surge current flowing through it, is equivalent to the valve open. According to the features, it can suppress the circuit often appear abnormal over-voltage protection
Protect circuitry from overvoltage damage.
