Single Zener Diodes Procurement Notes

Verify the specific suffix /TR indicates tape and reel packaging configuration against official Microchip documentation. Confirm that the JANS prefix denotes full military qualification standards required for your application. Ensure the DO-204AH package dimensions match your PCB footprint requirements before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when high accuracy and military reliability are mandatory. The ±1% tolerance suits critical regulation tasks. Compare against standard commercial variants if cost reduction is prioritized over radiation hardness or extended temperature ranges. Verify lead availability due to specialized manufacturing processes.

Single Zener Diodes Part Context

This part belongs to the JANS series of qualified Zener diodes from Microchip Technology. It shares functional similarities with the 1N4123 family but offers enhanced quality control and traceability for defense applications. The device serves as a robust voltage regulator in harsh operational conditions where standard components may fail.

Single Zener Diodes Replacement Considerations

JANS1N4123D-1 is a compatible non-reel variant. Standard 1N4123D-1 lacks military qualification. Verify electrical equivalence and package compatibility before substitution.

Single Zener Diodes FAQ

What is the Zener impedance of the JANS1N4123D-1/TR?

Specific Zener impedance values are defined in the official Microchip datasheet for this component.
