Power Dissipation Ratings
Should transients occur in rapid succession, the average power
dissipation result 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.The operating values must be derated as shown
in Figure 1.
