MIL-PRF-19500/507F
4.3.1 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 4.5.2.a, in polarity A 10 times (screening and group B) and 50 times
(group C) at TA = +25°C.
b. Pulse in accordance with 4.5.2.a, in polarity B 10 times (screening and group B) and 50 times
(group C) at TA = +25°C.
c. Read ID and VBR in polarities A and B at TA = +25°C, remove defective devices and record the
number of failures.
d. Apply the working peak reverse voltage (VWM) (column 4 of table II) in polarity A at TA = +125°C
as follows:
(1) For 48 hours (JANTX and JANTXV).
(2) For 170 hours (JAN, JANTX, and JANTXV) for group B steady-state operation life test.
(3) For 500 hours for group C steady-state operation life test.
e. Read ID in polarity A at TA = +25°C. Devices with ĆID > 50 percent (100 percent for steady-state operation
life) of the initial reading or 1 µA dc, whichever is greater shall be considered defective. Remove defective
devices and record the number of failures (see NOTE).
f. Apply the working peak reverse voltage (VWM column 4 of table II) in polarity B at TA = +125°C as follows:
(1) 48 hours (JANTX and JANTXV).
(2) 170 hours (JAN, JANTX, and JANTXV) for group B steady-state operation life test.
(3) 500 hours for group C steady-state operation life test.
g. Read ID in polarity B at TA = +25°C. Devices with Ć ID > 50 percent (100 percent for steady-state operation
life) of the initial reading or 1 µA dc, whichever is greater shall be considered defective. Remove defective
devices and record the number of failures (see NOTE).
h. Read VBR in polarities A and B at TA = +25°C. Devices with ĆVBR > 2 percent (±5 percent for steady-state
operation life) of the initial reading shall be considered defective. Remove defective devices and record the
number of failures (see NOTE).
i. Read ID in polarity A at TA = +25°C, remove defective devices and record the number of failures.
NOTE: For the purpose of this test, the direction in which the device is first pulsed shall be considered polarity A and
the reverse direction polarity B.
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 MIL-PRF-19500 and table I
herein. End-point electrical measurements shall be in accordance with table I, subgroup 2 herein.
