Power Dissipation Ratings
Should transients occur in rapid succession, the average
power dissipation required is simply 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.
