Single Zener Diodes Procurement Notes

Verify the specific ordering suffix required for your manufacturing process. The PBFREE designation indicates lead-free plating compliance. Confirm that the DO-35 through-hole package aligns with your PCB footprint requirements. Ensure the 250mW power rating is sufficient for your circuit's thermal conditions. Cross-reference the marking code C4619 for quality assurance during incoming inspection.

Single Zener Diodes Selection Notes

Select this component when low noise density is critical for the application. The 3.0V nominal voltage makes it suitable for specific reference needs within the series. Consider the DO-35 package constraints for board space. Evaluate the maximum reverse current specifications against your leakage requirements. Compare the impedance characteristics with other series members if different voltage levels are needed.

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 covers voltages from 1.8V to 6.2V, all sharing similar low-noise and low-leakage design goals. These devices are intended for applications requiring stable performance under low current conditions.

Single Zener Diodes Replacement Considerations

Direct substitutes include other 1N4619 equivalents from different manufacturers meeting the same DO-35 and electrical specifications. Verify that any replacement maintains the 5% tolerance and low noise density requirements. Check for compatibility with the existing PCB mounting style.
