scope:

This specification covers the general requirements for hermetically sealed or encapsulated solid state relays (SSR)(see 6.1), incorporating semiconductor, microelectronic, and passive circuit devices.

(Shall appear on individual specification sheets.)

Class I (discrete) construction: SSR utilizing this type of construction, employs only discrete type components, which can be nonhermetically sealed. The completed SSR is hermetically sealed.

Class II (hybrid) construction: SSR utilizing this type of construction, employs chip (die) and wire bond construction. The completed SSR is hermetically sealed.

The term Part of Identifying Number (PIN) is equivalent to the term part number which was previously used in this specification. The military PIN shall consist of the letter "M", the basic number of the specification sheet, an assigned dash number (see 3.1), and a screening level. The screening level indicates the level of quality and reliability. This specification currently provides only one level (see 3.7 and 6.8). Beneficial comments (recommendations, additions, deletions) and any pertinent data which may be of use in improving this document should be addressed to: Defense Electronics Supply Center, ATTN: EMM, Dayton, OH, 45444-5270 using the self addressed Standardization Document Improvement Proposal (DD Form 1426) appearing at the end of this document or by letter.

This appendix establishes the procedures for the testing of the elements used in the construction of Class II solid state relays to assist in achieving a level of quality and reliability commensurate with the intended application. It shall be used in conjunction with other documentation such as MIL-STD-883, the solid state relay specification sheet (see 3.2) and an applicable element detail specification to establish the design, material, performance, control, and documentation requirements which are needed to achieve prescribed levels of quality and reliability. This appendix is a mandatory part of the specification. The information contained herein is intended for compliance.

intended Use:
