V120ZT05

TVS - Varistors, MOVs

A TVS - varistor, also known as a transient voltage suppressor, is an electronic device designed to provide a fast-responding protection against transient overvoltage, as well as provide a reliable static protection. It is a type of surge protector that works by providing a very low reactance path for quick energy transients. It is primarily used to protect other electronic components in a circuit, such as integrated circuits, transistors, relays, and other sensitive equipment from high surge currents and spikes that can cause damage to the device or destroy the entire circuit.

MOVs, or metal-oxide varistors, are another type of protection device used against surges and spikes. It function similarly to a varistor, but instead of providing a low impedance path for transient currents, they provide a high impedance to limit current flow. MOVs are used in high power applications and provide a cost-effective solution for protecting expensive equipment.

The V120ZT05 is an ultra-low capacitance transient voltage suppressor which can offer a variety of operating voltage ratings, a low off-state capacitance, and a reverse pulse protection to guard against ESD and other pulse events. The device offers outstanding circuit protection with low capacitance and provides reliable protection to sensitive components.

The working principle of the V120ZT05 is quite simple—when a voltage higher than the tested voltage is applied to the device, it reduces the voltage to a level below the event to protect any connected components. It then enters an off-state until the voltage returns to normal and the protection cycles again. The device also has features such as reverse pulse protection which minimizes voltage stress and offers additional protection during abnormal overvoltage events.

The V120ZT05 is mainly used in industrial and automotive applications, such as in solar cell inverters, industrial sensors, LED lighting, and resistive heating elements. It provides a reliable protection against voltage transients, as well as static overvoltage, ensuring that the connected components remain safe even in extreme conditions. It is also highly compatible with a wide range of electronic components and devices, making it an ideal choice for any application.
