TVS - Varistors, MOVs

The V180ZU10PX2855 is a Varistor, also known as a Metal Oxide Varistor, or MOV. It is a two-terminal, nonlinear electronic component with a variable positive temperature coefficient of resistance. MOVs provide surge protection and are used to protect sensitive electronic circuits from power surges, or ElectroMagnetic Interference (EMI) and Radio Frequency Interference (RFI).The V180ZU10PX2855 is designed for application in electronic equipment, which is subject to lightning, EMI, and RFI. It is suitable for home appliances, computers, communication base stations, measuring instruments, etc. It is designed to protect devices and circuits from temporary overvoltages, such as lightning strikes and power surges due to switching of inductive loads.The V180ZU10PX2855 has a high maximum operating voltage of up to 10,120V and a high clamping voltage of up to 379V, making it suitable for use in many high voltage applications. Its high dielectric capability also makes it suitable to be used in harsh, high voltage environments.The working principle of Varistors is based on their highly nonlinear, reversible, temperature-dependent resistance behavior, which is unique for their type of electrical component. This resistance behavior enables them to act as both current and voltage limiters. In normal conditions, the resistance of Varistors is small and the component does not affect the circuit in any way. However, when the voltage-frequency of the input alternating current exceeds a certain threshold, the resistance of the Varistor increases rapidly, limiting the imposed current. In other words, the Varistor is capable of clamping sudden voltage spikes to safe values, allowing the electronic equipment to continue working without any disruption or damage.In addition to their surge protection capabilities, Varistors are also used in filtering applications, such as EMI and RFI attenuation. As mentioned before, their highly nonlinear resistance behavior enables them to act as both current and voltage limiters, thus making them excellent for attenuation of high frequency electromagnetic interference.In conclusion, the V180ZU10PX2855 is a Varistor, which is suitable for many high voltage applications, due to its high maximum operating and clamping voltages. It is used in surge protection applications, such as protecting sensitive electronic circuits from power surges, and in EMI and RFI attenuation applications. The working principle of Varistors is based on their highly nonlinear, reversible, temperature-dependent resistance behavior, which makes them excellent for clamping sudden voltage spikes and for attenuation of high frequency electromagnetic interference.
