*The curves shown are typical for the highest voltage device in the volt-

age grouping. Typical reverse current for lower voltage selections can

be estimated from these same curves if VR is sufficiently below rated VR.

PEAK POWER, Ppk, is peak of an

equivalent square power pulse.

∆TJL = Ppk • RθJL [D + (1 – D) • r(t1 + tp) + r(tp) – r(t1)]

where

∆TJL = the increase in junction temperature above the lead temperature

r(t) = normalized value of transient thermal resistance at time, t, from Figure 4, i.e.:
