DUTY CYCLE, D = tp/t1

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, i.e.:

r(t1 + tp) = normalized value of transient thermal resistance at time,

t1 + tp, etc.
