NOTE: Average power dissipation of transients not to exceed 0.25W, 0.4W, 0.6W or 1W for model sizes 7mm, 10mm, 14mm and 20mm, respectively.
Power Dissipation Ratings
PERCENT OF RATED VALUE
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 Specifications table for the specific device.The
operating values of a MOV need to be derated at high temperatures as
shown in Figure 1. 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.
