• Reference voltage sources

Single Zener Diodes Procurement Notes

Verify the specific suffix requirements against the official datasheet, as variations such as TR indicate tape-and-reel packaging while other suffixes may denote bulk or different environmental qualifications. Confirm that the selected variant meets all necessary military or industrial standards required for the intended deployment environment before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a robust surface-mount Zener diode is required for high-temperature environments. The DO-213AB package offers a compact footprint suitable for space-constrained designs. Ensure the 1.5W power rating and 8.2V breakdown voltage align with the circuit's thermal and electrical constraints.

Single Zener Diodes Part Context

This part belongs to the JAN series of Zener diodes produced by Microchip Technology, formerly Microsemi. The JAN designation typically indicates parts qualified for military or aerospace standards. The UR-1 suffix specifies the surface-mount MELF package format within this product line.

Single Zener Diodes Replacement Considerations

JAN1N3018UR-1/TR is a verified substitute offering identical electrical specifications but supplied in tape-and-reel packaging for automated assembly processes.
