MIL-PRF-19500-495 Semiconductor Device, Unitized, Dual-Transistor, Npn, Silicon Types 2N5793, 2N5794, And 2N5793A, 2N5794A, 2N5794U, 2N5794Uc, 2N5794Au, 2N5794Auc, Jan, Jantx, Jantxv, Jans, Jansm, Jansd, Jansp, Jansl, Jansr, Jansf, Jansg, And JanshScope. This specification covers the performance requirements for unitized, dual transistors which contains a pair of electrically isolated matched and unmatched NPN, silicon transistors in one package. Four levels of product assurance are provided for each device type as specified in MIL-PRF-19500. 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.
