Clamping voltage versus peak pulse current.
Exponential waveform tp = 20 µs
tp = 1 ms ——————-
tp = 10 ms ...............
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 :
∆VBR = αT * [Tamb -25] * VBR(25°C).
For intermediate voltages, extrapolate the given results.
