Power Derating Curve

Surge Current Standard Waveform

O1 = Virtual Origin of Wave T = Time from 10% to 90% of Peak T1 = Rise Time = 1.25 x T T2 = Decay Time

Example - For an 8/20 μs Current Waveform:

　　　 8μs = T1 = Rise Time 　　　 20μs = T2 = Decay Time

Should transients occur in rapid succession, the average power dissipation is the energy (watt-seconds) per pulse times the number of pulses per second. The power so developed must be with the specifications shown on the Device Ratings and Specifications Table for the specific device.The operating values of a MOV need to be derated at high temperatures as shown above. Because varistors only dissipate a relatively small amount of average power they are not suitable for repetitive applications that involve substantial amounts of average power dissipation. ．

Specifications are subject to change without notice.
