Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm plating options. The PBFREE designation indicates lead-free compliance, while alternative TIN/LEAD variants require explicit suffix addition. Confirm package type and marking codes match design requirements before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when low noise density and minimal reverse leakage are critical design constraints. Ensure the required Zener voltage falls within the 1.8 V to 6.2 V range covered by the series. Verify that the 250 mW power dissipation rating meets the thermal management capabilities of the target application environment.

Single Zener Diodes Part Context

This part belongs to the 1N4614 through 1N4627 series of silicon Zener diodes manufactured by Central Semiconductor Corp. The series is characterized by its focus on low noise and low current operation, utilizing a DO-35 axial leaded case. Higher voltage alternatives in the same product family are available in the 1N4099 series.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering DO-35 packaged Zener diodes with similar 2.2 V nominal voltage and 250 mW power ratings. Verify compatibility regarding maximum reverse current, Zener impedance, and noise density specifications to ensure equivalent circuit performance.
