DUTY CYCLE, D = tp/t1
PEAK POWER, Ppk, is peak of an
equivalent square power pulse.
DTJL = Ppk • RqJL [D + (1 − D) • r(t1 + tp) + r(tp) − r(t1)] where:
DTJL = 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.
