Temperature De-rating
When transients occur in rapid succession, the average power dissipa-
tion 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 Specifications table for the specific
device. For applications exceeding 125
o
C ambient temperature, the peak
surge current and energy ratings must be derated as shown in Figure 1.
