TVS (transient voltage suppressors) and MOVs (metal-oxide varistors) are devices that can protect electronic devices from transient overvoltage. Circuits with TVSs and MOVs are designed to limit excessive voltage to satisfy the power requirements of downstream devices. The ROV05H390K is one such device.

The ROV05H390K is a varistor device that provides protection from high-energy transients. It has an extremely low resistance during normal operation, but can quickly clamp transients to a safe level. This varistor has a high surge current rating and wide operating voltage range for exceptional stability and consistent performance.

The ROV05H390K is designed to be used in a variety of applications such as AC surge protection, DC line protection, and motor control. In AC surge protection applications, the ROV05H390K can be used to protect against surges on the input side of the circuit due to lightning or other high-energy transients. The wide operating voltage range of the ROV05H390K allows it to be used on both AC and DC circuits.

In motor control applications, the ROV05H390K can provide protection against surges during start-up and shutdown. The high surge current rating will help protect the motor control system from catastrophic failure during these power events. The ROV05H390K can also be used in DC line protection applications, where it will provide the same power protection for downstream devices.

The working principle of the ROV05H390K is based on the Zener effect. This effect occurs when a reverse-biased diode is subjected to a high electric field. In the ROV05H390K, the thin film of metal-oxide is the reverse-biased diode that undergoes the Zener effect. The thin film of metal-oxide is made up of a lattice of aluminum, zinc, and silicon particles that form a conducting path when an electric field is present. As the electric field increases, the metal-oxide lattice will start to become ionized and the resistance of the lattice will decrease. This decrease in resistance will cause a decrease in the voltage across the diode and the ROV05H390K will clamp the transient voltage to a safe level.

The ROV05H390K is a powerful and versatile device for providing AC and DC line protection, as well as protection from motor control transients. Its wide operating voltage range and high surge current rating make it an ideal choice for a wide range of applications. The working principle of the ROV05H390K is based on the Zener effect, which helps to ensure reliable and consistent performance.
