- Voltage regulation in industrial control equipment
Procurement Notes
Verify the specific suffix requirements against the official datasheet to ensure compatibility with your design specifications. Confirm that the component meets all necessary environmental and reliability standards for your intended application before finalizing procurement decisions.
Selection Notes
Select this component when high stability over temperature is critical. The 500 mW power rating and axial package make it suitable for general-purpose regulation where space allows for through-hole implementation. Ensure the circuit design accounts for the specified test current conditions.
Part Context
This part belongs to the 1N47xx series of Zener diodes manufactured by Microchip Technology. The series offers various voltage options within the 0.5 W power class, utilizing standard DO-35 glass encapsulation. The 'TR' suffix indicates reel packaging for automated assembly processes.
Replacement Considerations
Direct substitutes include other 1N4767 variants from different manufacturers that match the 22 V, 500 mW, and DO-35 package specifications. Verify electrical parameters such as impedance and leakage current to ensure functional equivalence.
