MIL-PRF-19500/608D
4.3.2 Thermal impedance. The thermal impedance measurements shall be performed in accordance with method
4081 of MIL-STD-750 using the guidelines in that method for determining IM, IH, tH, and tMD. Measurement delay
time (tMD) = 70 µs max. See table III, subgroup 4 herein.
4.3.3 Avalanche energy test. The avalanche energy test is to be performed using the circuit as shown on figure 6
or equivalent. The Schottky rectifier under test shall be capable of absorbing the reverse energy, as follows: IRM =
2 A minimum, L = 260 µH.
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 table E-V of
MIL-PRF-19500, and table I herein. Electrical measurements (end-points) and delta requirements shall be in
accordance with the applicable steps of table II herein.
4.4.2 Group B inspection. Group B inspection shall be conducted in accordance with the conditions specified for
subgroup testing in tables E-VIa (JANS) and E-VIb (JAN, JANTX, and JANTXV) of MIL-PRF-19500 and as follows.
Electrical measurements (end-points) shall be in accordance with table I, subgroup 2, forward voltage test (VF1) and
reverse leakage test (IR1) herein. Delta measurements shall be in accordance with table II herein.
