NOTE:
1. Average power dissipation of transients should not exceed 0.25W, 0.4W, 0.6W and 1.0W for 7mm, 10mm, 14mm, and 20mm model sizes,
respectively.

Power Dissipation Ratings
Should transients occur in rapid succession, the average power dissipa-
tion 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. Furthermore, the operating values need to be derated at high
temperatures as shown in Figure 1. Because varistors can only dissipate
a relatively small amount of average power they are, therefore, not
suitable for repetitive applications that involve substantial amounts of
average power dissipation.
