This specification covers the performance requirements for low-power, PNP, silicon transistors for use in high-speed, switching and general purpose amplifier applications. A \'M\' and UB \'M\' suffix will indicate a matched pair. Four levels of product assurance are provided for each encapsulated device type as specified in MIL-PRF-19500, and two levels of product assurance are provided for each unencapsulated device type. Provisions for radiation hardness assurance (RHA) to eight radiation levels is provided for quality levels JANTX, JANS, JANHC, and JANKC. 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.
