TVS – Varistors, MOVs are a type of electronic component used to protect circuits, mainly from transient overvoltages and unwanted surges. ROV20H301K-2 is a well-known device currently available on the market, suitable for overvoltage protection applications. This article provides an overview of its application fields and working principles.

Application

ROV20H301K-2 is mainly used in telecommunication systems. It is suitable for protecting low voltage analog and digital circuits, as well as signal lines and low power drivers from transient voltage surges caused by lightning. It is also capable of providing a high degree of protection from electrostatic discharges, ensuring a more reliable system performance in a variety of demanding environments.

Working Principle

The working principle of the ROV20H301K-2 is based on the Multi-Layer Varistor (MLV) design. By taking advantage of the reverse-biased P-N junction, the varistor acts as a voltage-dependent resistor. Therefore, when a transient surge is applied, the varistor absorbs the excess energy, thus limiting the peak voltage to a predetermined level. Furthermore, its low resistance at normal operation ensures the circuits are not significantly affected.

In addition, the device is equipped with multiple layers of metal-oxide layered dielectric material and a guard-ring electrode around the dielectric. This combination is able to allow a larger current conduction path when transient voltages rise above the Varistor’s voltage rating, thus providing protection against high levels of transient overvoltage.

Conclusion

ROV20H301K-2 is an effective component for protecting circuits from dangerous transient overvoltages and unwanted surges. Used in various telecommunications applications, the device takes advantage of the Multi-Layer Varistor design and the guard-ring electrode to provide reliable circuit protection. This makes it a reliable choice for a wide variety of applications.
