To determine maximum junction temperature of the diode in a
given situation, the following procedure is recommended:
DUTY CYCLE, D = tp/t1
PEAK POWER, Ppk, is peak of an
equivalent square power pulse.
The temperature of the case should be measured using a
thermocouple 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 pulsed operation once steady±state conditions are
achieved. Using the measured value of TC, the junction
temperature may be determined by:
TJ
= T

TJC
where TJC
is the increase in junction temperature above the case
temperature, it may be determined by:
