Single Zener Diodes Procurement Notes

Verify the specific manufacturer lot and date code upon receipt to ensure compliance with project timelines. Confirm that the received components match the 1N4464C designation exactly, as variations may exist between original Microchip production and other authorized distributors. Inspect leads for straightness and solderability before assembly to prevent mechanical stress during PCB insertion.

Single Zener Diodes Selection Notes

Select this component when a fixed 9.1 V reference is required with minimal drift. The DO-41 package offers superior heat dissipation compared to smaller surface-mount alternatives, making it ideal for environments where thermal management is critical. Ensure the circuit design accounts for the 1.5 W power rating to maintain operation within safe thermal limits under continuous load conditions.

Single Zener Diodes Part Context

This part belongs to the standard Zener diode family produced by Microchip Technology. It utilizes glass-passivated junction technology typical of the 1N series, ensuring long-term reliability. The DO-41 package is a legacy axial form factor widely used in industrial and commercial electronics, providing a balance between performance and ease of manual or automated assembly.

Single Zener Diodes Replacement Considerations

Direct substitutes include parts from the same 1N44xx series with identical voltage and power ratings. Verify pinout compatibility and thermal resistance characteristics when considering cross-brand equivalents to ensure seamless integration without redesigning the host circuit board.
