RA Series Ratings & Specifications
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 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 aver-
age power dissipation.
