To determine maximum junction temperature of the diode in a given
situation, the following procedure is recommended.
The temperature of the case should be measured using a thermocou-
ple placed on the case at the temperature reference point (see the
outline drawing on page 1). The thermal mass connected to the case
is normally large enough so that it will not significantly respond to heat
surges generated in the diode as a result of pulse operation once
steady state conditions are achieved.
Using the measured value of T
C
, the junction temperature may be
determined by:
T
J
= T
C
+ T
JC
Where T
JC
is the increase in junction temperature above the case
temperature, it may be determined by:
