TVS - Varistors, MOVs

TVS (Transient Voltage Suppressors) provides protection through the use of a device called a Varistor, MOV (Metal Oxide Varistor) or TVS Diode. The Varistor and MOV are basically electrically conductive plates separated by a dielectric material and programmed with an internal processing algorithm. The internal processing algorithm determines how much voltage must be exceeded before the varistor or MOV helps to prevent the disruption of a system.The ROV20-331K-2 is a metal oxide varistor with a maximum working voltage of 330 VDC, and a higher power rating compared to other varistors. This can be used in a variety of applications and provide protection from spikes or other forms of electrical surges. The ROV20-331K-2 also has a dielectric strength of 1.2kV, which makes it ideal for high voltage and high power applications. Additionally, it has a good clamping ability and a low leakage current, which improve the durability and reliability of the device.The working principle of the ROV20-331K-2 is based on the movement of electrons. Under normal circumstances, electrons move from the plate at the positive pole to the plate at the negative pole. When a voltage spike is detected by this varistor, the individual electrons in the device are polarized, so that they move from the plate at the negative pole to the plate at the positive pole. This change of direction triggers the release of electrons between the two plates, creating an electric arc, which acts to dissipate the surge voltage and protect the system from disruption.The ROV20-331K-2 can be used in many applications due to its features, such as its ability to provide noise suppression, overvoltage protection, current limiting, and voltage regulation. It is especially useful in the field of automotive and industrial electronics, as it can provide reliable and effective protection from unexpected voltage spikes.Overall, the ROV20-331K-2 is an excellent example of a metal oxide varistor that can provide reliable and effective protection from unexpected voltage spikes. It has a higher power rating than other varistors, and its noise suppressing, overvoltage protection, current limiting, and voltage regulation features make it especially useful in automotive and industrial electronics applications. With its good clamping ability and low leakage current, the ROV20-331K-2 is a reliable and effective device that can provide protection from unexpected voltage spikes.
