4.4.5 Group E inspection. Group E inspection shall be conducted in accordance with the conditions specified for
subgroup testing in table E-IX of MIL-PRF-19500 and as specified in table IV herein. Electrical measurements (end-
points) shall be in accordance with table I, subgroup 2 herein; delta measurements shall be in accordance with the
applicable steps of table II.
4.5 Methods of inspection. Methods of inspection shall be as specified in the appropriate tables and as follows.
4.5.1 Pulse measurements. Conditions for pulse measurement shall be as specified in section 4 of
4.5.2 Inspection conditions. Unless otherwise specified herein, all inspections shall be conducted at a case
temperature (TC) of +25°C.
4.5.3 Group B accelerated life test. This test shall be conducted using one of the four options listed herein (a, b, c,
or d) with the following conditions applying to all options: VCB = 30 V dc.
a. TA = +150°C, maximum, t = 96 hours minimum, TJ = +275°C.
b. PT = 2.5 W (TO-66); PT = 1.2 W (TO-5, U3 suffix), TA = +112°C or PT adjusted to give a lot average of
TJ = +275°C, t = 96 hours minimum, TJ = +275°C.
c. TA = +25°C +3 °C with PT adjusted to give a lot average of TJ = +275°C, t = 96 hours minimum, TJ = +275°C.
d. Adjust TA or PD to achieve a TJ = +225°C minimum. t = 216 hours, n = 45, c = 0.
