Varistor Voltage
Maximum Allowable
Voltage
Test Condition/Description
The voltage between two terminals with the specified measuring current
1mA.DC applied is called Vb.
The recommended maximum sine wave voltage (RMS) or the Maximum
DC voltage can be applied continuously.
The maximum voltage between two terminals with the specification
standard impulse current.
Applied waveform: 8/20μs

To meet the
Specified value
Rated Wattage
The maximum average power that can be applied within the specified
ambient temperature.
The maximum energy within the varistor voltage change of ±10% when
one impulse of 10/1000μs or 2ms is applied.
The maximum current within the varistor voltage change of ±10% with
the standard impulse current (8/20μs) applied one time.
The change of Vb shall be measured after the impulse listed below
which is applied 10,000 times continuously with the interval of ten
seconds at room temperature.
