The temperature of the lead should be
measured using a thermocouple placed on the
lead as close as possible to the tie point. The
thermal mass connected to the tie point is
normally large enough so that it will not
significantly respond to heat surges generated
in the diode as a result of pulsed operation
once steady–state conditions are achieved.
Using the measured value of TL, the junction
temperature may be determned by:
TJ = TL + TJL
20 k
LEAD LENGTH = 1/4
ZJL(t) = RJL
r(t)
TJL = Ppk RJL[r(t)]
where:
TJL = the increase in junction temperature above the
lead temperature
r(t) = normalized value of transient thermal resistance at
time, t fromthis figure. For example,
r(tp) = normalized value of
transient resistance at time tp.
