Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required tape-and-reel configuration, as packaging variations exist within the product family. Confirm RoHS compliance status, as military variants may differ from commercial equivalents. Ensure the supplier provides traceability documentation consistent with JANS procurement requirements. Cross-reference the specific datasheet revision to validate electrical parameters against design specifications before finalizing orders.

Single Zener Diodes Selection Notes

Select this component when a precise 6.8 V reference is required in a surface-mount form factor. The ±2% tolerance offers tighter accuracy than standard commercial Zener diodes. Consider the 500 mW power rating for thermal management in dense PCB layouts. The wide temperature range suitability makes it appropriate for harsh environment deployments where standard silicon devices would fail.

Single Zener Diodes Part Context

This part belongs to the JANS series of Zener diodes produced by Microchip Technology. The JANS designation indicates a specific level of quality assurance and screening intended for space and military applications. It is distinct from commercial counterparts by its rigorous testing protocols and material controls designed to prevent failure modes common in extreme conditions.

Single Zener Diodes Replacement Considerations

Direct replacements must match the DO-213AA footprint and 6.8 V Zener voltage. Verify that substitute components meet the same military qualification standards if the application requires JANS-level reliability. Check pinout compatibility and ensure the replacement supports the required 500 mW power dissipation.
