Figure 3. Maximum Reference Temperature
The temperature of the lead should be measured using a ther‐
mocouple 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
