MIL-PRF-19500/474G
4.5.6 Isolation current (IR ); bridging current(IRbr). These devices shall be subjected to the isolation
current/bridging current tests as specified:
a. For types 1N5772, 1N5774, 1N6496, 1N6508, and 1N6509, the bridging current shall be measured by
supplying the forcing function to every other interconnect pin and measuring the remaining interconnect
pins (excluding common anode and common cathode pins), IRbr. Repeat the test, reversing the polarity
of the forcing function.
b. For types 1N6100, 1N6101, 1N6511, and 1N6510, the bridging current shall be measured by applying the
forcing function to every other diode (anode and cathode simultaneously) and measuring the remaining
diodes (anode and cathode simultaneously), IRbr. Repeat the test, reversing the polarity of the forcing
function.
c. For types 1N5774, 1N6496, and 1N6509, the isolation current shall be measured between the individual
circuits by applying the forcing function to the anode and cathode of one circuit and measuring to the
anode and cathode of other circuit, IRi. Repeat the test, reversing the polarity of the forcing function.
d. For types 1N5768 and 1N6506, the forcing function shall be applied to every other anode and measured
on the remaining anodes, IRbr. Repeat the test, reversing the polarity of the forcing function.
e. For types 1N5770 and 1N6507, the forcing function shall be applied to every other cathode and measured
on the remaining cathodes, IRbr. Repeat the test, reversing the polarity of the forcing function.
4.5.7 Free air power burn-in and life tests. The use of a current limiting or ballast resistor is permitted provided
that each device under test still sees the full Pt (minimum) and that the minimum applied voltage, where applicable,
is maintained throughout the burn-in period.
