Test Condition / Description

Requirement

Maximum Allowable

Voltage

The recommended maximum sine wave voltage (RMS) or the maximum DC

voltage can be applied continuously.

Varistor Voltage

The voltage between two terminals with the specified measuring current

1mA.DC applied is call Vb.

Maximum Clamping

Voltage

The maximum voltage between two terminals with the specification

standard impulse current.

Applied waveform: 8/20μs

Rated Wattage

The maximum average power that can be applied within the specified

ambient temperature.

Energy

The maximum energy within the varistor voltage change of

±10% when one

impulse of 10/1000μs. or 2 msec. is applied.

Withstanding Surge

Current

The maximum current within the varistor voltage change of

±10% with the

standard impulse current (8/20

ȝsec.) applied one time

To meet the
