VDC DC working voltage
The maximum sustained DC voltage at which the varistor is used at highest operating temperature.
VAC AC working voltage
The maximum sustained sinusoidal AC operating voltage at which the varistor is used at the highest operating temperature.
IL Leakage current
The varistor is in a high-impedance state in non-conductive mode, to measure the leakage current at max. continuous working voltage.
VB Varistor
Threshold voltage that the varistor switches from the open circuit state to the working state. Normally measured at the current of 1mA DC.
VC Clamping voltage
The maximum voltage on a varistor under the condition of a specified pulse current and a 8/20us waveform condition or a ESD waveform.
CP Capacitance
The capacitance value of the varistor that measured at 1MHz frequency and 0.5V voltage (AC).
IR Insulation Resistance
The resistance value of the varistor that measured at 3.6V voltage (DC).
