1/
Tests to be performed on all devices receiving radiation exposure.
2/
For sampling plan, see MIL-PRF-19500.
3/
Electrical characteristics apply to all device types unless otherwise noted.
4/
Subgroup 1 is an optional test and must be specified on the purchasing contract when required.
5/
See method 1019 of MIL-STD-750 for how to determine [hFE] by first calculating the delta (1/hFE) from the pre-
and Post-radiation hFE. Notice the [hFE] is not the same as hFE and cannot be measured directly. The [hFE]
value can never exceed the pre-radiation minimum hFE that it is based upon.
