Unless specially, specified, temperature, relative humidity are 5 °C to 35 °C, 45 to 85% RH respectively. ——— Maximum Allowable Voltage The maximum DC voltage that can be applied continuously in the specified environmental temperature range. Short Time Over-Voltage The maximum DC Voltage that can be applied specified period without breakdown Varistor Voltage Voltage between both terminals of ZNR measured when 1 mA of To meet the DC current is applied under standard conditions. It is called V1. specified value. Measuring the varistor voltage should be made promptly to avoid heat affection. Clamping Voltage The maximum voltage between two terminals with the specified impulse current (8/20 µs). The test waveform of transient voltage which specified JASO Category A A-1 70 V without breakdown.
