TVS,also known as Transient Voltage Surge Suppressor, is an electronic component used to protect circuits, equipment and personnel from electrostatic discharge (ESD) and transients such as lightning strikes and power surges. Varistors, MOVs, and their derivatives are all products of transient voltage surge suppressors. ROV20H112K-2 is a kind of transient voltage surge suppressor, its application field and working principle are introduced in this article.

Application Field of ROV20H112K-2

ROV20H112K-2 is a type of voltage sensitive universal VARISTOR specifically designed for medium power applications. This TVS is especially suitable for the protection of electrical equipment due to switching transients up to 17V. Its application fields mostly concentrate on overvoltage protection, motor drives, power regulators, LCD TV, signal and communications, consumer electronics, ITE, appliances and medical equipment.

The Working Principle of ROV20H112K-2

ROV20H112K-2 uses symmetrical discharging method to reduce the surge current passing through the TVS. When an overvoltage occurs, the ROV20H112K-2 TVS metal oxide varistor will activate to absorb the overvoltage and limit its maximum amplitude. The TVS will start clamping when the voltage of the system rises more than the maximum permissible, thus the TVS can reduce or eliminate the surge current passing through the protection point.

In addition, ROV20H112K-2 has a fast metal oxide breakdown process. It is basically composed of a discharge chip and two metal oxide varistors. The time from the start of the breakdown to the varistors becoming closed is only several nanoseconds. That means ROV20H112K-2 can provide adequate protection against fast, high-energy surge currents.

Conclusion

ROV20H112K-2 is a special kind of TVS (Transient Voltage Surge Suppressors) widely used in many applications. It has a modern symmetrical discharge and fast metal oxide breakdown structure that enables it to protect circuits and equipment against ESD and transients caused by lightning strikes and power surges. Now people can have a better understanding of ROV20H112K-2 application field and working principle.
