Single Zener Diodes Procurement Notes

Verify the specific suffix 'E3' confirms RoHS compliance status as per manufacturer documentation. Confirm package type matches DO-204AH requirements for your assembly process. Check for any military or aerospace qualification markings if required for your application. Ensure ordering quantities align with distributor availability constraints.

Single Zener Diodes Selection Notes

Select this component when precise voltage referencing is critical over a broad temperature spectrum. The temperature compensation feature distinguishes it from standard Zener diodes, making it ideal for high-stability analog circuits. Consider the 500 mW power rating for thermal management planning. Verify that the axial leaded package fits your mechanical constraints compared to surface-mount alternatives.

Single Zener Diodes Part Context

This part belongs to Microchip's legacy 1N825 series of temperature-compensated Zener diodes. The 'E3' suffix typically denotes lead-free and RoHS-compliant manufacturing. These diodes are engineered for applications where standard Zener drift would compromise system accuracy. They serve as direct replacements for older non-RoHS versions in modern compliant designs.

Single Zener Diodes Replacement Considerations

The 1N825A-1E3 serves as a parameter-equivalent alternative. Verify pinout compatibility and ensure the replacement meets the same temperature coefficient specifications. Cross-reference datasheets to confirm identical voltage tolerance and power dissipation ratings before substitution.
