Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix corresponds to the tin/lead plating and tape-and-reel packaging format required for your assembly process. Confirm RoHS compliance status as the base part may be non-compliant depending on the specific manufacturer variant. Ensure the supplier provides official datasheets matching the exact part number to validate electrical parameters before procurement.

Single Zener Diodes Selection Notes

Select this component when a 6.2V regulation point is required in a through-hole axial package. Consider the 0.5W power rating and 175°C maximum operating temperature for thermal management. Verify compatibility with existing circuit designs requiring low-level Zener regulation in standard DO-35 footprints.

Single Zener Diodes Part Context

This part belongs to the 1N4678-1 through 1N4717-1 series of 0.5-watt Zener voltage regulators. These devices offer a selection of voltages from 1.8 to 43 volts with standard 5% tolerances. The series is characterized by axial-leaded glass construction and internal metallurgical bonding, originally developed for commercial versions of military-specified components.

Single Zener Diodes Replacement Considerations

Equivalent parts include other manufacturers' 1N4691 variants in DO-35 packages. Verify pinout orientation and voltage tolerance matches the original design requirements.
