The EZJ-Z0V800AA is a multilayer varistor manufactured by Panasonic. It is designed to provide transient and overvoltage protection for electronic circuits, and its maximum rated voltage is 80V. Its design includes two layers of non-conductive ceramic with an internal metal layer. This metal layer is connected to two external contacts, and when a spike or surge in voltage occurs, the metal layer will act as a resistor to safely absorb the energy and protect the circuit from damage. The varistor also has a low clamping voltage, which helps to minimize the amount of voltage that is allowed through the circuit.
