Peak Current and Energy Derating Curve
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 Specifications Table for the
temperature, the peak surge current and energy ratings
must be derated as shown below.
