Single Zener Diodes Procurement Notes

Verify the specific suffix 'D' against official Microchip documentation to confirm exact tolerance and testing parameters, as suffixes often denote specific quality grades or binning criteria. Ensure the procurement channel provides valid traceability records, particularly if the application requires compliance with specific military or industrial standards associated with this part number series.

Single Zener Diodes Selection Notes

Select the 1N4626D when a 5.6 V regulation point is required with moderate power handling capabilities. Consider the DO-35 package constraints regarding thermal management and board space. Compare against alternative Zener diodes with tighter voltage tolerances or higher power ratings if the circuit demands exceed the specified 0.4 W dissipation limit or require stricter voltage stability under varying load conditions.

Single Zener Diodes Part Context

This component belongs to the broader family of axial-leaded Zener diodes manufactured by Microchip Technology. These devices are commonly used in general-purpose electronics for simple voltage regulation tasks. The 1N4626D specifically addresses the need for a reliable 5.6 V reference in through-hole designs, offering a balance between performance and cost-effectiveness for standard industrial and commercial applications.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other 5.6 V Zener diodes in the DO-35 package with similar power ratings, such as the 1N4626B or 1N4626C, provided their tolerance specifications meet the design requirements. Verify pinout compatibility and thermal characteristics before substitution.
