Test Condition / Description
Requirement
Maximum Allowable The recommended maximum sine wave voltage (RMS) or the maximum DC
Voltage
voltage can be applied continuously.
The voltage between two terminals with the specified measuring current
1mA.DC applied is call Vb.
Varistor Voltage
The maximum voltage between two terminals with the specification
standard impulse current.
Applied waveform: 8/20μs
Maximum Clamping
Voltage
To meet the
specified value
The maximum average power that can be applied within the specified
ambient temperature.
Rated Wattage
Energy
The maximum energy within the varistor voltage change of ±10% when one
impulse of 10/1000μs. or 2 msec. is applied.
Withstanding Surge The maximum current within the varistor voltage change of ±10% with the
Current
