MIL-PRF-19500-441 Semiconductor Device, Transistor, Pnp, Silicon, Power Types 2N3740, 2N3740U4, 2N3741, And 2N3741U4, Jan, Jantx, Jantxv, Jans, Jansm, Jansd, Jansp, Jansl, Jansr, Jansf, Jansg, Jansh, Janhcc, Jankcc, Jankccm, Jankccd, Jankccp, Jankccl, Jankccr, Jankccf, Jankccg, And JankcchThis specification covers the performance requirements for PNP, silicon, power transistors. Four levels of product assurance are provided for each encapsulated device type as specified in MIL-PRF-19500. 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 JANTXV, JANS, JANHC, and JANKC 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.
