MIL-PRF-19500/434E
4.4.2.2 Group B inspection, table E-VIB (JAN, JANTX, and JANTXV of MIL-PRF-19500. Subgroup 3: Condition
4.4.3 Group C inspection. Group C inspection shall be conducted in accordance with the conditions specified for
subgroup testing in table E-VII of MIL-PRF-19500. Electrical measurements (end-points) and delta requirements
shall be in accordance with the applicable steps of table II herein.
a. Subgroup 2: The conditions for terminal strength are as follows: Lead tension: Test condition A;
weight = 5 pounds; t = 15 �3 s.
Lead fatigue: Test condition E; weight = 8 ounces.
b. Subgroup 6: The condition for steady-state operation life is as follows: See 4.5.1, 1 ms pulse only (see
4.5.3.b).
c. Subgroup 8: The conditions for temperature coefficient of breakdown voltage are as follows: I(BR) =
d. Subgroup 8: The conditions for maximum peak pulse current are as follows: See 4.5.3.a (20 �s pulse only)
ten pulses, sample size n = 22, c = 0.
* 4.4.4 Group E inspection. Group E inspection shall be conducted in accordance with the conditions specified for
subgroup testing in appendix E, table E-IX of MIL-PRF-19500 and as specified in table IV herein. Electrical
4.5 Methods of inspection. Methods of inspection shall be as specified in the appropriate tables as follows.
4.5.1 Power burn-in (HTRB) and steady-state operation life test conditions. The test conditions and order of
events shall be as follows:
a. Pulse in accordance with 4.5.3.b, 20 times (screening and group B) and 100 times (group C) at TA = +25�C.
b. Read ID and V(BR) at TA = +25�C, remove defective devices and record the number of failures.
(1) For 96 hours (JANTX and JANTXV) and 240 hours (JANS) for the screening test.
(2) For 340 hours (JANTX, and JANTXV) for group B steady-state operation life test.
(3) For 1,000 hours for group C steady-state operation life test.
d. Read and record ID and V(BR) at TA = +25�C. Devices with ĆID > 50 percent (100 percent for steady-state
operation life) of the initial reading or 1 �A dc, whichever is greater, or ĆV(BR) > �2 percent (�5 percent for
steady-state operation life) initial value shall be considered defective. Remove defective devices and record
the number of failures.
4.5.1.1 Group C steady-state operation life test (alternate procedure). When the group B 340 hour life test is
continued on test to 1,000 hours to satisfy the group C life test requirements, the test shall be performed as given in
4.5.1 herein with the following exceptions:
a. See 4.5.1 herein, step b shall be moved and performed following step e.
b. See 4.5.1 herein, step e shall be repeated after step b is performed.
