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/
See 6.2.e herein.
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 that [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.
