Procurement Notes

Verify that the specific part number includes the 'PBFREE' suffix to ensure compliance with lead-free plating requirements as defined by the manufacturer. Confirm the presence of the 'C4627' marking code on the component body to validate authenticity against the official datasheet specifications. Ensure the procurement documentation explicitly references the Central Semiconductor Corp datasheet for the 1N4614 through 1N4627 series to guarantee correct electrical characteristics and mechanical dimensions are met.

Selection Notes

Select this component when designing circuits requiring stable voltage regulation with minimal noise interference. The 6.2 V nominal voltage and 5% tolerance make it suitable for precision analog applications. Consider the 250 mW power dissipation limit and the extensive thermal operating range when determining placement within high-density or thermally constrained environments.

Part Context

This component belongs to the 1N4614 series of silicon Zener diodes manufactured by Central Semiconductor Corp. The series covers voltages from 1.8 V to 6.2 V, all sharing similar low-noise design characteristics and the standard DO-35 package form factor. This specific model represents the highest voltage option within this particular low-power series.

Replacement Considerations

Cross-reference with other manufacturers offering 1N4627 equivalents in the DO-35 package. Verify that substitute parts maintain the 6.2 V nominal Zener voltage, 250 mW power rating, and comparable low noise density specifications to ensure circuit compatibility.
