Procurement Notes
Verify the specific suffix 'R0G' against official manufacturer documentation to confirm reel packaging specifications. Ensure compatibility with standard axial leaded handling procedures. Confirm RoHS compliance status as indicated in the datasheet. Validate that the DO-41 package dimensions match the target PCB layout requirements before finalizing procurement orders.
Selection Notes
Select this component when a stable 24 V reference is required in high-temperature environments up to 175°C. The DO-41 package suits applications needing robust through-hole mounting. Verify that the 1 W power rating accommodates the expected thermal load. Consider the 25 Ohm impedance for circuit stability requirements.
Part Context
This part belongs to the 1N47XXG series of Zener diodes from Taiwan Semiconductor. The series covers a wide voltage range from 3.3 V to 56 V. These devices are characterized by their hermetically sealed glass packages and compression bonded construction, ensuring reliability in various industrial and commercial applications.
Replacement Considerations
Cross-reference with other manufacturers' 1N4749A or 1N4749 variants. Ensure equivalent Zener voltage, power dissipation, and package type. Verify that replacement parts meet the same temperature and leakage current specifications.
