This specification is approved for use by all Departments
and Agencies of the Department of Defense.
The requirements for acquiring the product described herein shall consist of
this specification sheet and MIL-PRF-19500.
1. SCOPE
1.1 Scope. This specification covers the performance requirements for NPN, silicon, switching transistors. Five
levels of product assurance are provided for each encapsulated device type as specified in MIL-PRF-19500, and 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.
* 1.2 Physical dimensions. See figure 1 (similar to TO-18), figure 2 (surface mount case outline UA), figure 3
(surface mount case outlines UB, UBC, UBN, and UBCN), and figures 4, 5, and 6 (JANHC and JANKC).
* 1.3 Maximum ratings. Unless otherwise specified T = +25 C.
