Procurement Notes
Verify component authenticity through authorized Bourns distributors or direct channels. Confirm RoHS compliance status against the latest datasheet revision. Ensure storage conditions adhere to moisture sensitivity level requirements prior to soldering. Validate that the specific ordering suffix matches the required electrical parameters for the target application design.
Selection Notes
Select this component for applications requiring compact SOD-123 footprint integration. Consider the 1 A current rating and 40 V reverse voltage limits during circuit design. Evaluate thermal management needs based on the specified junction-to-ambient resistance. Compare forward voltage specifications against alternative Schottky diodes to ensure optimal system efficiency.
Part Context
This part belongs to the CD123D-B1xR Schottky Barrier Chip Diode Series. The series provides silicon rectification in a compact package designed for portable communications, computing, and video equipment. It addresses industry demands for smaller electronic components and minimal PCB real estate usage while maintaining high current capability.
Replacement Considerations
Consult official Bourns documentation for verified substitute part numbers within the CD123D-B series. Cross-reference electrical parameters such as forward voltage and reverse leakage current when evaluating alternatives.
