Single Zener Diodes Procurement Notes

Verify the specific suffix UR-1/TR against official Microchip documentation to confirm the round-end lead configuration and tape-and-reel packaging format. Ensure the component meets required RoHS compliance standards for your manufacturing process. Cross-reference the datasheet for exact mechanical dimensions and thermal characteristics before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when a 7.5 V Zener reference is required in a surface-mount design. The DO-213AA-2 package offers space efficiency compared to through-hole alternatives. Verify that the 500 mW power dissipation rating and 200 Ohm impedance align with the specific load and thermal requirements of the target application circuit.

Single Zener Diodes Part Context

This part belongs to the 1N4100 series of Zener diodes manufactured by Microchip Technology. The series includes various voltage ratings within the same physical footprint family. The UR-1 designation typically indicates a specific lead form factor, while /TR denotes reel packaging for automated assembly processes.

Single Zener Diodes Replacement Considerations

Direct replacements include the non-tape version JANTX1N4100UR-1 or standard 1N4100 variants if through-hole mounting is acceptable. Verify pinout compatibility and ensure equivalent voltage and power ratings are maintained during substitution.
