TA or IO to obtain a minimum TJ of +150°C (see 4.5.1).
4.4.4 Group E inspection. Group E inspection shall be conducted in accordance with the tests and conditions
specified for subgroup testing in table E-IX of MIL-PRF-19500, and table II herein. Electrical measurements (end-
points) shall be in accordance with table I, subgroup 2 herein.
4.5 Methods of inspection. Methods of inspection shall be as specified in the appropriate tables and as follows.
4.5.1 Free air power burn-in and life tests. The use of a current limiting or ballast resistor is permitted provided
that each device under test still sees the full Pt (minimum) and that the minimum applied voltage, where applicable, is
maintained throughout the burn-in period. Method 3100 of MIL-STD-750 shall be used to measure TJ.
4.5.2 Pulse measurements. Conditions for pulse measurements shall be as specified in section 4 of
MIL-STD-750.
