APPLICATION NOTE
The Data of Figure4 applies for typical wire terminal or printed
circuit board mounting conditions in still air. Under these or simi· lar conditions, the thermal resistance between the diode junctions and the leads at the edge of the case is a small fraction of the thermal resistance from junction to ambient. Consequently. the lead
temperature is very close to the"junction.
