Procurement Notes
Verify the specific suffix UR-1/TR against official Microchip documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the DO-213AA case. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement decisions.
Selection Notes
Select this component when a 33 V regulation point is required in a compact surface-mount form factor. The wide operating temperature range makes it suitable for applications exceeding standard commercial limits. Verify that the 500 mW power rating aligns with the expected thermal load in the target design environment.
Part Context
This part belongs to the 1N47xx series of Zener diodes manufactured by Microchip Technology. The UR-1 designation typically indicates a specific surface-mount variant, often corresponding to the DO-213AA package. This series is widely used for voltage regulation and protection in various electronic assemblies.
Replacement Considerations
Cross-reference with other manufacturers offering 33V 500mW SMD Zener diodes in DO-213AA packages. Ensure equivalent electrical parameters such as voltage tolerance and leakage current are met. Verify pinout compatibility if substituting with non-Microchip equivalents.
