Varistor, also called voltage-dependent resistor (VDR), is a type of voltage regulator used in various electronic circuits. It is an important component for protection and current limitation of electronic equipment. V68ZC20PX2855 is one of the varistors, which is widely used for the protection of our TVS and MOVs.

The V68ZC20PX2855 contains two important parts: a zinc oxide material and a metal oxide material. The zinc oxide material has a very high excitation voltage and improves the power-limiting effect of MOV. The metal oxide material has a lower excitation voltage and can work as an arc-proof protection function. It has a wide range of tolerances from 20 to 6K V and can perform excellent protection from high surge energy or impact current.

In terms of its application, the V68ZC20PX2855 varistor is suitable for surge protector in consumer electronics, DC ESD, TVS and MOVs, such as TV, DVDs, and computers. It is also used in industrial applications, such as motor control, medical equipment, telecommunication equipment, and so on.

The working principle of the V68ZC20PX2855 is quite simple. It works to limit or regulate voltages by watching the voltage rise and fall in any electrical circuit. When the voltage rises higher than the clamping voltage of the varistor, it will begin to conduct and reduce the impact on the electrical components. The excess current will be shunted away from the components to the varistor thus protecting them from any further damage.

V68ZC20PX2855 is designed with two working states, which are the standby state and the working state. In the standby state, the varistor generally exhibits a very low resistance, such as 0.25 ohms. In the working state, when the voltage rises higher than the rated clamping voltage of the varistor, it will begin to conduct and reduce the impact on the electrical components.

To sum up, V68ZC20PX2855 varistor is applicable to TVS and MOVs and works in two different states. In the standby state, it features a low resistance and in the working state, it reduces the impact of the electrical components. With its wide range of tolerance and excellent protection, V68ZC20PX2855 is becoming more and more popular in the field of TVS and MOVs.
