Test Condition / Description

Requirement

Varistor Voltage The voltage between two terminals with the specified measuring

current 1mA.DC applied is call Vb.

To meet

the specified

value

Maximum

Allowable

Voltage

The recommended maximum sine wave voltage (RMS) or the

maximum DC voltage can be applied continuously.

Rated Wattaget The maximum average power that can be applied within the specified

ambient temperature.

IEnergy

The maximum energy within the varistor voltage change of ±10% when one

impulse of10/1000μsec. or 2 msec. is applied.

Withstanding

Surge

Current

The maximum current within the varistor voltage change of ±10% with the

standard impulse current (8/20μsec.) applied one time.

Surge Life

The change of Vb shall be measured after the impulse listed below is

applied 10,000 times continuously with the interval of ten seconds at room

temperature.
