Single Zener Diodes Procurement Notes

Verify the specific suffix CUR-1 against official Microchip documentation to confirm the exact reel or bulk packaging configuration. Ensure that the procurement channel provides valid traceability records required for components certified to MIL-PRF-19500/437 standards. Confirm RoHS exemption status as these parts are typically non-compliant with standard RoHS directives due to their military qualification.

Single Zener Diodes Selection Notes

Select this component when a precise 14V reference is required in space-constrained surface-mount designs. The DO-213AA package offers a compact footprint suitable for automated assembly. Consider the high thermal limit and hermetic seal if the application involves extreme temperatures or corrosive atmospheres where standard plastic packages would fail.

Single Zener Diodes Part Context

This part belongs to the 1N5534 series of Zener diodes produced under military quality controls. It shares the same electrical characteristics as commercial variants but differs in manufacturing processes, testing rigor, and physical sealing methods. The 'JANTX' prefix indicates a specific grade within the Microchip military product line.

Single Zener Diodes Replacement Considerations

Direct substitutes include JAN1N5534CUR-1 for standard military grade or 1N5534B for through-hole equivalents. Verify pinout compatibility and package dimensions before replacing with non-Microchip manufacturers to ensure mechanical fit.
