Figure 3. Peak pulse power versus 
exponential pulse duration
a. The curves of 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 formula: ΔV
BR
 = αT * [T

(25 °C). For intermediate 
voltages, extrapolate the given results.
