scope:
This specification covers the detail requirements for NPN, silicon, switching transistors. Four levels of product assurance are provided for each device type as specified in MIL-S-19500. Provisions for radiation hardness assurance (RHA) to four radiation levels is provided for JANTXV and JANS product assurance levels. RHA level designators "M", "D", "R", and "H" are appended to the device prefix to identify devices which have passed RHA requirements.
See figures 1 and 2 (similar to a TO-18), figures 3 and 4 (surface mount case outlines UA and UB), and figure 5 (JANC).
