Figure 1: Pulse waveform (10/1000µs)

Figure 2: Peak power dissipation versus initial

junction temperature (printed circuit board)

Figure 3: Peak pulse power versus exponential

pulse duration

Figure 4: Clamping voltage versus peak pulse

current (note 5)

Note 5: The curves of the figure 4 are specified for a junction temperature of 25°C before surge. The given results may be extrapolated for

other junction temperatures by using the following formula :

For intermediate voltages, extrapolate the given results.
