Procurement Notes
Verify the specific suffix 'ATR' against the manufacturer's official documentation to confirm packaging details and availability status. Ensure the component meets RoHS and REACH compliance requirements for your target market. Cross-reference the datasheet revision date to validate electrical parameters before integration into design specifications.
Selection Notes
Select this component when a 13 V regulation point is required in a through-hole assembly. The DO-41 package offers robust mechanical stability for standard PCB layouts. Consider the 1 W power rating and wide operating temperature range for applications involving significant thermal loads or harsh environmental conditions.
Part Context
This part belongs to the 1N47 series of Zener diodes manufactured by onsemi. The series is widely recognized for providing reliable voltage regulation in various electronic circuits. The 1N4743ATR variant specifically utilizes tape-and-reel packaging, facilitating automated surface-mount or through-hole insertion processes in high-volume manufacturing environments.
Replacement Considerations
Compatible substitutes include the 1N4743A from Rectron and the 1N4743AHA0G from Taiwan Semiconductor. Verify that alternative sources match the 13 V Zener voltage, 1 W power rating, and DO-41 package dimensions to ensure functional equivalence.
