TVS - Varistors, MOVs

The V82ZU4PX2855 is a versatile and reliable device used in a variety of applications. Its most common uses are in surge protection, overvoltage protection and circuit isolation. In these roles, it provides protection against power surges, spikes and electrostatic discharge events.The V82ZU4PX2855 utilizes a unique design which combines a varistor with an overvoltage protection device and a dual N-channel metal-oxide-silicon (NMOS) diode. This combination allows the device to provide surge protection, overvoltage protection and efficient isolation.Varistors are devices which contain a set of metal-oxide elements which act as a non-linear resistance, thereby limiting the voltage and current passing through it. This is used to protect sensitive electronics from overvoltages, spikes, and surges. The varistor element in the V82ZU4PX2855 is optimized to provide effective surge protection between 10 and 42V.When a surge or spike is detected, the overvoltage protection device and the varistor in the V82ZU4PX2855 act in concert to reduce the voltage and current passing through. This protects the circuits of the device and prevents damage from the surge. The protection device is also effective for ESD events.The dual N-channel MOS diode in the V82ZU4PX2855 provides two-way isolation. It acts as a one-way shutter and prevents currents from passing in either direction. This provides a further layer of protection and prevents short-circuits and other problems caused by the flow of current in both directions.The V82ZU4PX2855 is a versatile and reliable device that can be used in a variety of applications. Its combination of surge protection, overvoltage protection and efficient isolation makes it an ideal choice for protecting sensitive electronics from power surges, spikes and electrostatic discharge events.
