Procurement Notes

Verify the specific part number against official Micro Commercial Components documentation to confirm exact electrical tolerances and packaging options. Ensure compatibility with design requirements regarding power dissipation and thermal management. Cross-reference datasheets for any updates on material compliance or mechanical dimensions prior to final procurement decisions.

Selection Notes

Select this component when a 39V reference is required in an axial through-hole configuration. Consider the 45 Ohm impedance and 1W power rating for thermal constraints. Verify that the ±5% voltage tolerance meets circuit precision needs. Compare against alternative series if lower impedance or different package styles are necessary for the specific application environment.

Part Context

This component belongs to the 1EZ series of 1W silicon Zener diodes manufactured by Micro Commercial Components. The series covers a voltage range from 5.6V to 39V in the DO-41 package. The 'TP' suffix indicates tape and reel packaging availability, while the base model denotes the specific voltage rating and standard axial form factor.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include the 1N4752AP-TP from the same manufacturer.
