MIL-PRF-19500M, PERFORMANCE SPECIFICATION: SEMICONDUCTOR DEVICES, GENERAL SPECIFICATION FOR (22 OCT 1999)., This specification establishes the general performance requirements for semiconductor devices. Detail requirements and characteristics are specified in the performance specification sheet. Revisions to this and performance specification sheets are structured to assure the interchangeability of devices of the same part type regardless of manufacturing date code or conformance inspection (CI) completion date. Five quality levels for encapsulated devices are provided for in this specification, differentiated by the prefixes JAN, JANTX, JANTXV, JANJ, and JANS. Seven radiation hardness assurance (RHA) levels are provided for the JANTXV and JANS quality levels. These are designated by the letters M, D, L, R, F, G, and H following the quality level portion of the prefix. Two quality levels for unencapsulated devices are provided for in this specification, differentiated by the prefixes JANHC and JANKC.MIL-PRF-32140, PERFORMANCE SPECIFICATION, RELAYS, ELECTROMAGNETIC, RADIO FREQUENCY, ESTABLISHED RELIABILITY, GENERAL SPECIFICATION FOR (14 JAN 2004)., This specification covers the general requirements for electromagnetic, RF hermetically sealed relays for use in electronic and communication-type equipment (see 6.1). These relays are designed to operate over the full range from low level to power switching with contact ratings up to 1 ampere direct current (dc). The failure rate level is established at a confidence level of 95 percent based on 1 million to 20 million cycles (see 1.3) at maximum ambient temperature (see 3.1).
