Single Zener Diodes Procurement Notes

Verify the specific suffix TR indicates tape and reel packaging when sourcing. Confirm RoHS compliance status as documentation may vary by production batch. Ensure the DO-213AA footprint matches the target PCB layout. Cross-reference the manufacturer part number with authorized distributors to confirm current availability and lead times.

Single Zener Diodes Selection Notes

Select this component for designs requiring a 12 V Zener voltage in a small surface-mount form factor. The 500 mW power rating suits moderate current applications. Verify that the 5% voltage tolerance meets circuit precision requirements. Consider the wide temperature range for harsh environment deployments.

Single Zener Diodes Part Context

This part belongs to the Microchip Technology Zener Diodes category under Diodes & Rectifiers. It is a variant of the standard 1N4699 series, adapted for surface-mount technology. The DO-213AA package offers a smaller profile compared to through-hole alternatives like DO-35.

Single Zener Diodes Replacement Considerations

Direct substitutes include other 12 V Zener diodes in the DO-213AA package with matching 500 mW ratings. Verify pinout compatibility and thermal characteristics before substitution.
