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 and as specified herein. Electrical measurements (end-points)
shall be in accordance with table I, subgroup 2 herein.

4.4.4 Group E inspection. Group E inspection shall be conducted in accordance with the tests and conditions
specified for subgroup testing in table E-IX of MIL-PRF-19500, and table II herein. Electrical measurements (end-
points) shall be in accordance with table I, subgroup 2 herein.
4.5 Methods of inspection. Methods of inspection shall be as specified in the appropriate tables and as follows.
4.5.1 Measurement of reverse current for 1N5772, 1N5774, 1N6496 1N6508, and 1N6509. For 1N5772,
1N5774, 1N6496, 1N6508, and 1N6509, the reverse current shall be measured using a circuit which bypasses the
shunt resistance through the other diodes not under test, around the current meter. Care should be taken to assure
that the voltage drop across the current meter is less than 10 millivolts.
4.5.2 Forward voltage. This parameter shall be measured 90 microseconds after the leading edge of the pulse.
4.5.3 Peak forward voltage. During this test, the maximum shunt capacitance across the diode shall be 19 pF
and the equipment bandwidth shall be 80 MHz minimum.
4.5.4 Pin-to-pin capacitance. This parameter is the total pin-to-pin capacitance across each individual diode and
may not necessarily represent actual diode capacitance since they are all connected together at either the anode or
cathode and these connections represent additional capacitance.
4.5.5 Reverse current (IRX) and forward voltage (VFX). Each common anode section and each common cathode
section shall be tested separately. Each diode in the test section shall be measured individually after the array
has reached thermal equilibrium.
