HA Series
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 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 for average power dissipation.
