TVS - Varistors, MOVsTVS, varistors, and MOVs are three types of solid-state devices that are used to protect sensitive components and systems from electrical surges. TVS stands for Transient Voltage Suppressors, varistors stand for Voltage Regulators, and MOV stands for Metal Oxide Varistors. These devices serve to provide protection against spikes and surges that may otherwise damage electronic equipment, and are often used in power circuits and in lightning protection. A ROV20-121K type TVS is a bidirectional TVS protection device designed to protect the connected components from voltage spikes generated by lightning, line faults, load dump, switching transients, and inductive coupling. This type of TVS also provides protection for both AC and DC signals over a wide frequency range. The ROV20-121K device consists of a zinc oxide varistor and a series of diodes that are connected in parallel. The varistor has a high breakdown voltage and provides excellent protection against voltage spikes. The diodes are connected in series to provide over-voltage protection and prevent induced current spikes. When a transient voltage spike is present, the varistor quickly responds and clamps the voltage to a level lower than the breakdown voltage of the circuit. This clamping action prevents excessive current from passing through the varistor and damaging sensitive components. At the same time, the series of diodes limit the current to prevent the varistor from blowing out. The ROV20-121K can be used in a variety of applications, including telecom, industrial, and consumer electronics. It provides protection against transient over-voltage and electromagnetic interference (EMI) for a wide range of connecting components. Additionally, it is compatible with a variety of voltage sources, including AC, DC, and switch-mode power supplies.In summary, the ROV20-121K is a robust, bidirectional TVS that provides superior protection against transient voltage spikes. It is available in a variety of form factors and is compatible with a wide range of voltage sources. The device is designed to provide reliable protection for both AC and DC signals, and offers superior protection against induced current spikes and over-voltage.
