- Voltage reference applications
Procurement Notes
Verify authenticity by purchasing directly from Micro Commercial Components or authorized distributors to avoid counterfeit parts. Confirm the specific suffix requirements, such as adding '-HF' for halogen-free versions if needed. Ensure the component meets quality standards for handling and storage as defined by the manufacturer.
Selection Notes
Select this component when a 20 V Zener voltage is required in a compact surface-mount form factor. Consider the 1 W power dissipation capability and the thermal resistance characteristics for heat management. Verify that the operating temperature range aligns with the intended environmental conditions.
Part Context
This part belongs to the 1N4729AW through 1N4761AW series of silicon planar power Zener diodes manufactured by Micro Commercial Components. The series covers a wide voltage range from 3.6 V to 75 V, all sharing similar packaging and general performance characteristics suitable for various electronic circuit designs.
Replacement Considerations
Cross-reference with other manufacturers offering 20 V, 1 W Zener diodes in the SOD-123 package. Ensure equivalent electrical parameters, particularly Zener voltage tolerance and dynamic impedance, are met before substitution.
