TVS - Varistors, MOVs

Varistors, also known as Metal Oxide Varistors (MOVs), are voltage-dependent resistors that can be used to protect electronic circuits from high-voltage transients such or those caused by electrostatic discharge (ESD), electro-magnetic interference (EMI), and lightning surges. They provide a high-impedance impedance for voltage levels below their clamping levels which goes down to low impedance levels for high-voltage transients that exceed the varistor’s clamping voltage.

VJ13PC0300KBA is a kind of MOVs. It’s a high-precision varistor with a minimum breakdown voltage of 330V AC and a peak pulse current of 10K Amps. It is designed to provide effective electromagnetic interference (EMI) protection and precise static discharge (ESD) protection solutions.

VJ13PC0300KBA has a wide application field. Due to its high-precision varistor for low-voltage protection and high-temperature stability feature, the VJ13PC0300KBA is suitable for applications such as automotive applications, home appliances, communication equipments, electronic security systems, and industrial control systems.

VJ13PC0300KBA’s working principle is simple. When an overvoltage greater than its punch-in voltage is detected, it starts to conduct current. Its punch-in voltage is 330V AC, and its clamping voltage is 405V AC. This high precision varistor can effectively limit high voltage transients to give safe protection for circuits from electrostatic discharge (ESD) or electromagnetic interference (EMI). After the overvoltage resolves itself, the varistor gradually returns back to its high impedance state with no residual current.

In short, the VJ13PC0300KBA is a high-precision varistor that is suitable for wide applications such as automotive, home appliances, communication equipments and more. It works by quickly clamping an overvoltage to provide effective EMI and ESD protection for sensitive circuits.
