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. The operating values must be derated as
shown in Figure 1.

CURVE
O 1 = Virtual Origin of Wave
T = Time From 10% to 90% of Peak
T 1 = Virtual Front time = 1.25 ? t
T 2 = Virtual Time to Half Value (Impulse Duration)
Example: For an 8/20 μ s Current Waveform:
8 μ s = T 1 = Virtual Front Time
20 μ s = T 2 = Virtual Time to Half Value
