This specification covers the performance requirements for PNP, silicon, power transistors for use in high-speed power-switching applications. Four levels of product assurance (JAN, JANTX, JANTXV, and JANS) are provided for each encapsulated device type as specified in MIL-PRF-19500. Provisions for radiation hardness assurance (RHA) to eight radiation levels ("M", "D", "P", "L", "R", "F", "G", and "H") are provided for JANTXV and JANS product assurance levels.
