Figure 2.

Pulse definition for electrical characteristics

The curves of Figure 5 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.
