Power Dissipation Ratings
When transients occur in rapid succession the average
power dissipation is 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 Characteristics table for the specific
device. Certain parameter ratings must be derated at high
temperatures as shown in Figure 1.
