• General-purpose rectification and clamping

Single Zener Diodes Procurement Notes

Verify the specific suffix 'A0G' against the manufacturer's official documentation to confirm packaging details and compliance status. Ensure the ordering information matches the exact part number to avoid discrepancies in package type or testing conditions. Cross-reference the datasheet revision date to validate parameter accuracy before integration into production designs.

Single Zener Diodes Selection Notes

Select this component when a precise 4.3 V reference is required in a standard axial leaded form factor. The 5% tolerance suits applications where tight voltage regulation is not critical. Consider the 500 mW power rating and DO-35 package dimensions for board space constraints. Verify that the 58 ohm impedance aligns with the dynamic load requirements of the target circuit design.

Single Zener Diodes Part Context

This component belongs to the 1N5229B series of silicon planar Zener diodes. The series covers a wide voltage range from 2.4 V to 200 V in the DO-35 package. The 1N5229B specifically targets the 4.3 V segment, offering a balance of performance and cost for general electronic applications requiring reliable voltage regulation.

Single Zener Diodes Replacement Considerations

Compatible substitutes include the Microsemi MQ1N5229BUR-1 and MLL5229C-1. Note that these alternatives utilize a MELF (DO-213AA) surface mount package rather than the axial DO-35 configuration. Verify mechanical fit and soldering process compatibility before substitution.
