About MOV Varistor

The resistor material of the varistor is a semiconductor, so it is one type of resistor. At present, most zinc oxide varistors are used. Its main raw materials are composed of divalent elements and hexavalent element O. Therefore, from the perspective of raw materials, zinc oxide varistor is a compound semiconductor material oxide semiconductor.

The relationship between the lightning protection effect of MOV multilayer varistor and the working voltage 

The function of the varistor in the circuit is for relay protection and resistance to electric shock.

The relay protection function of the varistor in the circuit can usually be combined with the current fuse to protect against electric shock or other relays. When selecting a type, what is the relationship between the lightning protection effect of the varistor and the voltage?

The voltage and current intensity of a varistor do not follow the Euclidean law but exhibit a nonlinear dependence. When the voltage applied on both sides is less than the nominal voltage, the resistance of the varistor is close to infinite, and there is almost no current passing through it.

When the voltage applied on both sides is slightly higher than the nominal voltage value, the varistor will quickly break down and conduct, and change from a high resistance state to a low resistance state, and the operating current will also increase rapidly. When the voltage applied on both sides is lower than the nominal voltage value, the varistor returns to its high resistance state. When the voltage applied on both sides exceeds the specified voltage value, the varistor will all break down and be destroyed, and will no longer be able to recover on its own.

Therefore, the relationship between the voltage of the varistor and the lightning protection effect is not that the higher the voltage, the better the lightning protection effect. The larger the voltage of the varistor, it will only make its overlapping function better. Quality is the lifeline of an enterprise and one of the magic weapons that establishes its competitiveness. Capacitor is one of the essential components in our closely related electronic equipment.

Description:

The 07D series radial leaded varistors provides an ideal circuit protection solution for lower DC voltage applications by offering higher surge ratings than ever before available in such small discs.
The maximum peak surge current rating can reach up to 1.75KA (8/20 μs pulse) to protect against high peak surges, including indirect lightning strike interference, system switching transients and abnormal fast transients from the power source.
