Procurement Notes

Verify the specific suffix configuration against official Microchip documentation to ensure compatibility with required packaging and compliance standards. Confirm that the component meets all necessary regulatory requirements for the intended deployment environment before finalizing procurement decisions.

Selection Notes

Select this component when a robust 33 V regulation point is needed in high-temperature environments. Ensure the circuit design accommodates the specified 1 W power dissipation and verify that the 45 Ohm impedance aligns with the noise and stability requirements of the application.

Part Context

This part belongs to the standard 1N47xx series of glass-passivated Zener diodes manufactured by Microchip Technology. These components are widely utilized in industrial and commercial electronics where reliable voltage clamping and reference capabilities are essential under varying thermal conditions.

Replacement Considerations

Cross-reference with other manufacturers' 1N4752A equivalents ensuring identical 33 V rating, 1 W power dissipation, and DO-41 package dimensions. Verify that substitute parts meet the same ±5% tolerance and temperature range specifications.
