TVS (Transient Voltage Suppressors) is a family of circuit protection devices designed to protect electronics from voltage spikes caused by lightning or unintended operation of other circuit elements. Varistors, also known as Voltage Dependent Resistors (VDRs), are one type of TVS.Metal Oxide Varistors (MOVs) are the most common form of varistors. The V82RA8 is an MOV specifically designed for industrial environments, where robust protection from voltage spikes or transient overvoltage is a requirement.

The V82RA8 has an operating voltage range of 8.2V-290V, which is considerably higher than other MOVs. It can also handle transients up to 6kV and 100A. Its compact size of 10x20mm allows for easy integration into various applications. Furthermore, its high surge capability can protect circuits from spikes resulting from nearby lightning strikes or other electrical transients.

The working principle of the V82RA8 is based on the "clamp action" mechanism of a MOV. A MOV is essentially a resistor whose resistance is dependent on the applied voltage. The V82RA8 MOV is composed of two MOV layers with zinc oxide as the active material. As the applied voltage increases, the amount of zinc oxide particles increases, resulting in higher conductance of the MOV. This increased conductance helps to limit the voltage spikes that can potentially damage sensitive electronic components.

When a surge is detected, the MOV begins to conduct and the voltage across it drops. The current then passes through the MOV and flows to ground, thus limiting the voltage and protecting the circuit. The MOV acts like a "clamp" to limit the voltage to a safe level. Once the surge is over, the MOV will reset itself and be ready to act again if needed. The V82RA8 also has a low surge rate, which helps to protect sensitive equipment from the gradual voltage rise caused by long-term over-voltage conditions, such as thunderstorms.

The V82RA8 is designed to be used in a variety of applications, such as industrial control systems, power supplies, LED lighting systems, and motor drives. It can also be used in medical equipment, home appliances, automotive systems, and many other applications that require robust protection from transients. The V82RA8 is an ideal solution for protecting sensitive electronics from dangerous voltage spikes.
