adjust 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,
maintained through-out the burn-in period. Method 3100 of MIL-STD-750 shall be used to measure TJ.
