* 4.4.2.1 Group B inspection, (JAN and JANTXV). Separate samples may be used for each step. In the event of a
lot failure, the resubmission requirements of MIL-PRF-19500 shall apply. In addition, all catastrophic failures during
CI shall be analyzed to the extent possible to identify root cause and corrective action.

Steady-state life: 1,000 hours minimum, VCB = 10 V dc, power shall be applied to achieve
TJ = +150°C minimum using a minimum of PD = 75 percent of maximum rated PT as defined
in 1.3. n = 45 devices, c = 0. The sample size may be increased and the test time
decreased as long as the devices are stressed for a total of 45,000 device hours minimum,
and the actual time of test is at least 340 hours.
Blocking life, TA = +150°C, VCB = 80 percent of rated voltage, 48 hours minimum.

* 4.4.2.3 Group B sample selection. Samples selected from group B inspection shall meet all of the following
requirements:
a. For JAN and JANTX samples shall be selected randomly from a minimum of three wafers (or from each wafer
in the lot) from each wafer lot. See MIL-PRF-19500.
b. Shall be chosen from an inspection lot that has been submitted to and passed table I, subgroup 2,
conformance inspection. When the final lead finish is solder or any plating prone to oxidation at high
temperature, the samples for life test (group B for JAN and JANTX) may be pulled prior to the application of
final lead finish.
* 4.4.3 Group C inspection, Group C inspection shall be conducted in accordance with the test and conditions
specified for subgroup testing in table VII of MIL-PRF-19500, and in 4.4.3.1 (JAN and JANTX) herein for group C
testing. Electrical measurements (end-points) and delta requirements shall be in accordance with table I, subgroup 2,
and table II.
