value

Maximum Allowable Voltage

The maximum sinusoidal RMS voltage or maximum DC voltage that can be

applied continuously in the specified environmental temperature range.

Clamping Voltage

The maximum voltage between two terminals with the specified standard

impulse current (8/20μs) illustrated below applied.

Rated Power

The power that can be applied in the specified ambient temperature.

Maximum Energy

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

one impulse of 2 ms or 10/1000 μs is applied.
