4.5.4 Thermal resistance. Thermal resistance measurements shall be conducted in accordance with test
method 3101 or 4081 of MIL-STD-750. Read and record data in accordance with group E herein and shall be
included in the qualification report. Forced moving air or draft shall not be permitted across the devices during
test. The maximum limit under these test condition shall be R

4.5.5 Peak reverse power test. A 20 microsecond half-sine waveform of current shall be used and peak reverse
power shall be determined by the product of peak reverse voltage and peak reverse current. A 20 microsecond
square waveform may also be used with the approval of the qualifying activity (see figure 9).
