The measurement should be made as fast as possible to avoid heat effects. To meet the specified 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 specified 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. Temperature Coefficient of Varistor Voltage VCmA at 85 °C – VCmA at 25 °C × 1 × 100(%/°C) VCmA at 25 °C 60 0 to –0.05 %/°C Impulse Life (I) The change of Vc shall be measured after the specified impulse is applied 10000 times continuously with an interval of 10 seconds at room temperature.
