V100ZU4PX2855

TVS-Varistors, MOVs are electronic components used to protect circuits from voltage surges. The V100ZU4PX2855 is a popular such component, and its application field and working principle are described in detail below.

Application Field

The V100ZU4PX2855 is ideally suited for personal computer, portable devices, automotive, and industrial equipment applications. It is suitable for use in circuits operating at operating voltages from 12V to 75V and pulse waveforms up to 1,200V.

This varistor has a unique, low-capacitance design, which provides optimum EMI/RFI protection. It also incorporates a bidirectional conduction block and a thermal shutdown that prevents the varistor from overheating.

The V100ZU4PX2855 is built to withstand a wide range of temperature and humidity conditions. It is also designed to provide a maximum level of protection even during short circuit and overload conditions.

Working Principle

The working principle of the V100ZU4PX2855 is based on the phenomenon of the metal-oxide-semiconductor (MOS) caps. It is a form of nonlinear resistor whose resistance varies depending on the applied voltage. As the voltage increases, the resistance decreases, allowing current to flow.

In operation, the V100ZU4PX2855 acts as a line of defense against voltage surges. It limits the voltage increase by diverting the excessive current away from the circuit. It does this by providing a very low resistance at higher voltages, making it easier for the current to pass through. Thus, it is able to protect the circuit from voltage spikes.

The V100ZU4PX2855 is also equipped with a thermal-delay feature which allows it to delay the response time to a transient surge voltage. This prevents the device from overloading and helps reduce the Total Cost of Ownership (TCO) of related systems.

Overall, the V100ZU4PX2855 is an excellent choice for voltage surge protection. It is reliable, highly efficient, and suitable for a wide range of applications. Its low-capacitance design and thermal-delay feature ensure it can handle even the most severe power fluctuation scenarios.
