Single Zener Diodes Procurement Notes

This component is officially marked as obsolete and discontinued by the manufacturer. Verify availability through authorized distributors or secondary markets, noting that supply may be limited. Confirm that the specific lot meets all required environmental and quality standards before integration into new designs.

Single Zener Diodes Selection Notes

Select this part only if legacy compatibility is required, as it has been replaced by surface mount equivalents. Evaluate thermal derating requirements carefully, as power dissipation must be reduced above 75°C lead temperature. Ensure the DO-35 form factor fits the existing board layout constraints.

Single Zener Diodes Part Context

The 1N5231B belongs to the 1N5221B through 1N5267B series of 500mW Zener diodes manufactured by Diodes Incorporated. This series covers a wide range of voltage ratings from 2.4V to 75V. The product line has been superseded by the MMSZ52xxB surface mount family.

Single Zener Diodes Replacement Considerations

Use MMSZ52xxB series parts as direct replacements. Verify that the selected surface mount equivalent matches the required voltage, power rating, and tolerance specifications.
