ROV07H680K-S-2 is an excellent choice for applications needing superior protection performance and is capable of reliably protecting against electrostatic discharge (ESD), high-voltage surges and transients. The use of this silicone carbide based varistor technology allows ROV07H680K-S-2 to offer a wider range of protective features, compared to other existing varistor technologies.

Working Principle

The working principle of the ROV07H680K-S-2 varistor is based on the breakdown properties of a silicon carbide dielectric material. This material allows the varistor to absorb ESD, high-voltage surges, or transients with minimal energy dissipation. The varistor is constructed with a metal oxide layer which, when exposed to a sufficient voltage, causes the silicon carbide material to break down. This breakdown effect is called the “avalanche breakdown” and creates a capacitance between the two plates. This capacitance is responsible for the ESD protection and surge absorption.

The breakdown properties of the silicon-carbide material are utilized in the ROV07H680K-S-2 varistor in order to provide reliable and superior protection from electrical transient and surges. When the voltage across the varistor exceeds the threshold, the varistor material begins to break down and conducts the surge to ground. The conducting effect creates a low resistance path for the ESD current to be discharged to the ground, but with low energy dissipation. Thus, thevaristor is capable of providing superior protection for a wide range of applications.

Conclusion

ROV07H680K-S-2 is a silicon-carbide based varistor technology that provides a reliable and superior protection solution for ESD, high-voltage surges and transients. It is designed for use in a variety of applications including home appliances, power supplies, industrial systems, data communications, and consumer electronics. The working principle of the ROV07H680K-S-2 utilizes the breakdown properties of a silicon-carbide dielectric which allows it to absorb ESD, surges, and transients with minimal energy dissipation. This provides a reliable and efficient protection solution for modern-day applications.
