MIL-PRF-19500-453 Semiconductor Device, Transistor, Npn, Silicon, High-Frequency Type 2N5109 And 2N5109Ub, Jan, Jantx, Jantxv, Jans, Janhc, Jankc Jasm, Jansd, Jansp, Jansl, Jansr, Jansf, Jansg, And JanshThis specification covers the performance requirements for NPN silicon, VHF-UHF amplifier transistors. Four levels of product assurance are provided for each device type as specified in MIL-PRF-19500. Two levels of product assurance are provided for die. Provisions for radiation hardness assurance \(RHA\) to eight radiation levels is provided for JANS 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.
