MIL-PRF-19500/503H
* 4.3 Screening (JANTX and JANTXV levels). Screening shall be in accordance with appendix E, table E-IV of
MIL-PRF-19500, and as specified herein. The following measurements shall be made in accordance with table I
herein. Devices that exceed the limits of table I herein shall not be acceptable.

1N6076 through 1N6078 = +1.0 µA dc.
1N6079 through 1N6081 = +5.0 µA dc.
4.3.1 Thermal impedance. The thermal impedance measurements shall be performed in accordance with method
3131 of MIL-STD-750 using the guidelines in that method for determining IM, IH, tH, tSW (VC and VH where
4.3.1.1 For initial qualification and re-qualification. Read and record data (ZθJX) shall be supplied to the qualifying
activity on one lot (random sample of 500 devices minimum) prior to shipment. Twenty-two samples shall be
serialized and provided to the qualifying activity for test correlation.
4.3.2 Power burn-in conditions. Power burn-in conditions are as follows (see 4.5.6.1): IO(min) = IO(rated). TA =
55°C maximum. Test conditions in accordance with method 1038 of MIL-STD-750, condition B. Adjust IO or TA to
achieve the required TJ. TJ = 135°C minimum. With approval of the qualifying activity and preparing activity,
alternate burn-in criteria (hours, bias conditions, TJ, mounting conditions) may be used for JANTX and JANTXV
quality levels. A justification demonstrating equivalence is required. In addition, the manufacturing site's burn-in data
and performance history will be essential criteria for burn-in modification approval.
4.3.3 Screening (JANHC). Screening of die shall be in accordance with appendix G of MIL-PRF-19500. As a
minimum, die shall be 100-percent probed to ensure compliance with table I, subgroup 2. Burn-in duration for the
JANHC follows JANTX requirements.
