Single Zener Diodes Procurement Notes

Verify the specific suffix 'C' indicates the required 2% tolerance level against project specifications. Confirm that the DO-204AH axial leaded package aligns with the target PCB footprint and assembly process requirements. Ensure the 0.5 W power rating is sufficient for the expected thermal conditions in the final application environment.

Single Zener Diodes Selection Notes

Select this component when a stable 4.3 V reference is needed with strict tolerance limits. The low leakage current of 500 nA makes it suitable for sensitive analog interfaces. Consider the axial package geometry for manual assembly or legacy board designs requiring through-hole mounting technology.

Single Zener Diodes Part Context

This part belongs to the standard 1N52xx series of Zener diodes manufactured by Microchip Technology.
