MIL-PRF-19500/550C
* 4.3.1 Screening (JANHC and JANKC). Screening of die shall be in accordance with appendix G of
MIL-PRF-19500, as a minimum die shall be 100 percent probed in accordance with group A, subgroup 2, except test
current shall not exceed 20 A.
4.3.2 Burn-in conditions. Burn-in conditions for all levels are as follows: Method 1038 of MIL-STD-750, test
condition A; TC = +125°C, VR = 0.8 to 0.85 rated dc (see 1.3), t = 48 hours.
4.3.2.1 Alternate burn-in conditions. TC = +150°C, VR = rated VR (see 1.3), IO = 0, f = 50 to 60 Hz, t = 48 hours.
4.3.3 Surge current. Surge current, see method 4066 of MIL-STD-750. IO = 0; VRWM = 0; IFSM = 800 A; six
surges; TA = +25°C; tp = 8.3 ms.
4.3.4 Thermal response ZθJX measurements. The ZθJX measurements shall be performed in accordance with
method 3101 of MIL-STD-750. The ZθJX conditions and maximum ZθJX limit shall be derived by each vendor and
shall not exceed the RθJC (see 1.3). The chosen ZθJX measurement and conditions for each device in the
qualification lot shall be submitted in the qualification report and a thermal response curve shall be plotted. The
chosen ΔVF value shall be considered final after the manufacturer has had the opportunity to test five consecutive
lots. tH = 100 to 250 ms; heating current IH = 30 A. Measurement current: 50 ≤ IM ≤ 250 mA; tMD ≤ 250 µs.
4.4 Conformance inspection. Conformance inspection shall be in accordance with MIL-PRF-19500.
4.4.1 Group A inspection. Group A inspection shall be conducted in accordance with appendix E, table E-V of
MIL-PRF-19500, and table I herein.
4.4.2 Group B inspection. Group B inspection shall be conducted in accordance with the conditions specified for
subgroup testing in appendix E, table E-VIb (JANTX and JANTXV) of MIL-PRF-19500 and as follows. Electrical
measurements (end-points) shall be in accordance with the applicable steps of table I, group A, subgroup 2 (VFM1
and IR1 only) herein.
* 4.4.2.1 Group B inspection, appendix E, table E-VIb (JANTX and JANTXV) of MIL-PRF-19500.
