This specification covers the performance requirements for PNP, silicon, power, 2N5151 and 2N5153 transistors, complimentary to the 2N5152 and 2N5154 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-19500/545 and Two levels of product assurance (JANHC and JANKC) are provided for each unencapsulated device type as specified in MIL-PRF-19500/545. 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.
