ROV20-621K is a form of TVS-Varistors, MOVs. It is an component provides electronic equipment with protection against transient voltage surges. It is usually used in power supplies, telecom systems, IT-systems and controllers where transient suppression is needed for system safety and data integrity. The ROV20-621K provides a high level of protection with low capacitance and resistance, allowing for high-speed transmission and system stability.

TVS-Varistors, MOVs are designed with nonlinear ceramic elements or metal oxide elements formation to provide bidirectional overvoltage surge suppression. They offer protection from transient voltage spikes, pulses and lightning. Commonly devices have large capacitance, and so can be used as snubber devices for suppressing high frequency overvoltages in motor drives, UPS, and rectifiers.

Working principle

ROV20-621K adheres to the Zener diode working principle and functions as an electrostatic activated, low resistance varistor. It has a voltage breakdown occurring between two electrodes. When the voltage applied between electrodes exceeds the breakdown voltage, the region between two electrodes become conductive. It provides instantaneous current path, so that the surge current in the initial stage of an overvoltage can be safely dissipated. When the voltage drops back below the breakdown voltage, the region between two electrodes becomes an open circuit, which makes the device return to the working condition.

ROV20-621K works through application of a wide range of current and voltage, capable of dealing with any situation. It is an irreplaceable safeguard in electronic systems, controlling the flow of current, regulating high peak current. Thereby, it ensures safety and avoid any equipment from damaging, malfunctioning or suffering data loss.

Application field of ROV20-621K

ROV20-621K is widely used in DC to DC converter, power adapter, energy-saving lighting, IC distributor, voltage voice recorder, DC-motor driver, vehicle and mobile equipment,various kinds of transformer, camera, printer and so on. It can handle loads between 0.1VDC and 5KV. This device is very useful in protecting the electrical system from overvoltage surges and other electrical shock.

ROV20-621K is also used for industrial applications due to its reliability and efficiency in suppressing overvoltage. It helps to protect the electronic systems from costly damages and destroy the equipment. ROV20-621K acts as an all-weather attendant to your equipment, providing 24/7 protection from the destructive transient voltage.
