DA/DB Varistor Series
DA/DB 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 average power dissipation.
