1N4622 BK TIN/LEAD

Single Zener Diodes Overview

The Central Semiconductor Corp 1N4622 BK TIN/LEAD is a silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 3.9 V with a standard tolerance of 5%. The component operates in a DO-35 glass axial-lead package, supporting through-hole mounting. It dissipates up to 500 mW of power and maintains functionality across an extended temperature range from -65 °C to +175 °C. The device utilizes tin/lead terminations and is configured as a single unidirectional unit.

Single Zener Diodes Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm termination composition and compliance status. Ensure the procurement channel sources directly from authorized distributors or the manufacturer to guarantee authenticity. Cross-reference the part number with current datasheets to validate electrical parameters before integration into designs.

Single Zener Diodes Selection Notes

Select this component when a 3.9 V regulation point is required in a compact axial-lead form factor. Consider the 500 mW power dissipation limit and the -65 °C to +175 °C operating range during thermal design. Verify that the DO-35 package dimensions align with the target PCB layout constraints.

Single Zener Diodes Part Context

This component belongs to the widely recognized 1N4614 through 1N4627 series of low-power Zener diodes. These devices are standard JEDEC registered parts commonly used in general electronics. The 1N4622 variant specifically targets the 3.9 V segment of this extensive voltage selection lineup.

Single Zener Diodes Replacement Considerations

Equivalent replacements include other manufacturers' 1N4622 variants or the JAN1N4622C military-grade version. Surface mount equivalents such as the MLL4622 series may be considered if package adaptation is feasible.
