Note : The curves of the figure 3 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 :

∆V (BR) = αT (V(BR)) * [Ta -25] * V (BR).

For intermediate voltages, extrapolate the given results.
