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 the diagram above. 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.
