Single Diodes Procurement Notes

Verify the specific suffix UR-1 against official Microchip documentation to confirm the exact reel packaging configuration and lead finish specifications. Ensure procurement channels provide valid traceability records required for defense or aerospace contracts. Confirm that the component meets the specific lot acceptance testing requirements defined in the applicable MIL-PRF-19500 revision.

Single Diodes Selection Notes

Select this component when a surface-mount switching diode with hermetic sealing is required for high-reliability environments. It serves as a direct replacement for through-hole axial variants like the JAN1N5195 when board space constraints necessitate the DO-213AA footprint. Verify thermal management capabilities align with the 500 mW dissipation limit in the final assembly.

Single Diodes Part Context

This part belongs to the JAN series of radiation-hardened and high-reliability semiconductors produced by Microchip's Microsemi division. These components are designed to meet stringent military quality standards, offering superior performance compared to commercial grade equivalents in terms of leakage current stability and long-term durability under extreme conditions.

Single Diodes Replacement Considerations

Direct pin-compatible replacements include the JAN1N5195 (through-hole variant) for prototyping. For surface-mount needs, verify equivalent MIL-spec diodes from other qualified manufacturers such as BAE Systems or L3Harris, ensuring identical voltage ratings and package dimensions.
