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 silicon, general purpose, semiconductor
diodes. 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.

1.2 Physical dimensions. See figure 1 (similar to DO-41) for 1N5550 through 1N5554, figure 2 for 1N5550US
through 1N5554US, and figures 3, 4, 5, 6, and 7 for JANHC and JANKC die.

1.3 Maximum ratings. Unless otherwise specified, T
C
= +25°C and ratings apply to all case outlines.
