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.
