Parameter Definitions
Varistor Voltage (breakdown voltage):
The varistor voltage is the voltage across the varistor measured at a specified current
Ic(0.1mA or 1mA) of specified duration.
Maximum allowable voltage:
The Maximum allowable voltage corresponds to the rest state of the varistor. The rest
state voltage offers a low leakage current in order to limit the power consumption of the
protected device and not disturb the circuit to be protected.
Maximum clamping voltage:
Maximum clamping voltage is the maximum voltage Vp between two terminals with a
specified standard impulse current (8x20 µ sec). The voltage vaule is an indication of the
protective function of the varistor.
