Power Dissipation Ratings

Peak Pulse CurrentTestWaveform

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 within the speciﬁcations shown on the

Device Ratings and SpeciﬁcationsTable for the speciﬁc

device.The operating values of a MOV need to be derated

at high temperatures as shown in the diagram below.

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.
