• Defense electronics operating in extreme thermal environments

Single Zener Diodes Procurement Notes

Verify JANS qualification status and specific datasheet revisions prior to procurement. Confirm that the DO-213AA footprint matches the target PCB design. Ensure supply chain sources are authorized to prevent counterfeit components in critical aerospace applications.

Single Zener Diodes Selection Notes

Select this component when radiation hardness and wide temperature operation are required. Compare against JANTX variants if space constraints allow through-hole mounting. Verify that the 500 mW power rating meets circuit dissipation requirements at maximum ambient temperatures.

Single Zener Diodes Part Context

This part belongs to the 1N4624 series of Zener diodes produced by Microchip's Microsemi division. The JANS suffix indicates it meets strict military and aerospace quality standards, distinguishing it from commercial or industrial grade equivalents in the same voltage class.

Single Zener Diodes Replacement Considerations

Public confirmed substitutes include JANTX1N4624DUR-1 for similar performance without JANS qualification. Cross-reference with other manufacturers' 4.7V SMD Zener diodes only if electrical parameters and radiation tolerance requirements are relaxed.
