This specification covers the performance requirements for PNP silicon transistors designed for use in high speed switching and driver applications. Four levels of product assurance are provided for each encapsulated device type and two levels of product assurance for each unencapsulated specified as in MIL-PRF-19500. Provisions for radiation hardness assurance (RHA) to eight radiation levels is provided for JANS product assurance levels. 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.
