Introduction

The V82ZU2P is a high-performance glass-coated metal oxide varistor (MOV) designed to offer the best protection for delicate equipment and wiring from dangerous transient voltage surges. With its unique construction and design features, the V82ZU2P provides best-in-class surge withstand capability and lower leakage current with a high breakdown voltage.

Application Field

The V82ZU2P is used for transient voltage surge suppression in electronics equipment and industrial applications. It is ideal for use in areas subject to high levels of energy surge caused by lightning strikes, electric arcs, and power system transients. More specifically, the V82ZU2P is used in data communication lines, control enclosures, machine control systems, telecommunications lines, computer and telephone systems, consumer electronic products, and line filtering or interference suppression in industrial facilities.

Working Principle

The V82ZU2P is a Varistor or voltage dependent resistor (VDR) which provides protection by rapidly reducing the voltage across a given circuit in the event of a surge. The VDR consists of two electrodes separated by an insulating material, and a semiconducting material which is a mixture of metal oxides. When the voltage across the electrodes exceeds a predetermined threshold, a sudden decrease in the resistance between the electrodes occurs, and the mov rest a protect the device or system. The V82ZU2P is able to handle more than 200A of 8/2 μs surge current, as well as up to 2000V surge voltage, due to its unique construction. The MOV usually has two layers with metal oxide grains in between and two electrodes connected to both layers that serve as gate electrodes. The gate electrodes can be connected to any external device, ensuring a low leakage current and instantaneous response when facing an overvoltage situation. The V82ZU2P also features a wide range of operating temperatures, ranging from -40 to +125 degrees Celsius, along with a low capacitance that enables better waveform attenuation of transient voltage surges. Furthermore, its small size and wide range of package types make it easy to integrate into electronic designs.

Conclusion

The V82ZU2P is an effective and versatile metal oxide varistor designed to protect electronics from voltage surge damage. It is designed to handle surface voltage surges of up to 2000V and provides best-in-class surge withstand capability and low leakage current with a high breakdown voltage. Its combination of low leakage current, fast response time, and wide range of operating temperatures make it ideal for a variety of industrial and electronic applications.
