Operating ambient temperature: -40°C to +85°C
Storage temperature: -40°C to +125°C *3 Transient peak current (Itm) The peak current rating, Itm, is based on 8/20µs test impulse wave form. This peak current is the maximum peak current at which the nominal varistor voltage shift dose not exceed ±10% when the test impulse is applied twice at a 5 minute interval. 4 * Nominal varistor voltage: Vnom Indicates the varistor terminal voltage measured with 1mA DC applied. 05A type 0.1mA DC *5 Maximum clamping voltage: Vc Indicates the peak terminal voltage measured with 8/20µs impulse current applied.
*1 The waveform of the maximum DC applied voltage is flat. When a ripple voltage as from a rectifier source is applied, make sure that the peak voltage is within the Vdcm rating. The AC applied voltage (50/60Hz) is a sine waveform. When waveform distortion is extensive, make sure that the peak voltage is less than 2 times the Vacm rating. 2 * Energy Wtm Transient energy rating are given in the Wtm column in Joules (Wattsecond). The rating is the maximum allowable energy of a si.
