Characteristics Test Methods Specifi cations
Standard Test
Condition
Electrical measurements (initial/after tests) shall be conducted at
temperature of 5 to 35 °C, relative humidity of maximum 85 % ———
Varistor Voltage
The voltage between two terminals with the specifi ed measuring
current 1mA DC applied is called V1 or V1mA. The measurement
should be made as fast as possible to avoid heat effects.
To meet the
specifi ed value.
Maximum Allowable
Voltage
The recommended maximum sinusoidal wave voltage (rms) or
the maximum DC voltage that can be applied continuously.
Clamping Voltage The maximum voltage between two terminals with the specifi ed
impulse current (8/20 μs).
Rated Power The maximum power that can be applied within the specified
ambient temperature.
Maximum Energy Maximum energy of less than ±10 % of the varistor voltage
change when the standard impulse (2 ms) is applied one time.
Maximum
Peak Current
Maximum current of less than ±10 % of the varistor voltage change
when impulse current (8/20 μs) is applied twice continuously with an
interval of 5 minutes.

The change of Vc shall be measured after the specifi ed impulse is
applied 10000 times continuously with an interval of 10 seconds at
room temperature.
