The requirements for acquiring the product described herein shall consist of
this specification sheet and MIL-PRF-19500.
1. SCOPE
1.1 Scope. This specification covers the performance requirements for PNP silicon, VHF-UHF amplifier
transistors. Four levels of product assurance are provided for each device type as specified in MIL-PRF-19500. Two
levels of product assurance are provided for each unencapsulated device type. Radiation hardness assurance (RHA)
level designators "M", "D", "P", "L", "R", "F", "G", and "H" are appended to the device prefix to identify devices which
have passed RHA requirements.
1.2 Physical dimensions. See figure 1 (TO-72) and figure 2 (surface mount) and figure 3 (JANHC and JANKC die).
