Procurement Notes
Verify the specific datasheet revision and RoHS compliance status prior to procurement, as specifications are subject to change without notice. Confirm that the ordering suffix matches the required voltage rating and packaging format. Ensure the component meets all safety-related requirements applicable to the target device or application environment before finalizing orders.
Selection Notes
Select this component for applications requiring high efficiency and low power loss in compact designs. The 3 A current rating and 40 V reverse voltage make it suitable for general-purpose rectification in portable electronics. Consider the operating junction temperature limits when designing thermal management solutions for enclosed environments.
Part Context
This part belongs to the CD214B-B3xR Series of Schottky Barrier Rectifier Chip Diodes. The series offers forward currents of 3 A with repetitive peak reverse voltages ranging from 20 V to 100 V. These diodes are designed for rectification applications in compact chip packages compatible with the DO-214AA (SMB) size format, addressing the industry demand for smaller electronic components.
Replacement Considerations
Compatible substitutes within the same series include CD214B-B320R, CD214B-B360R, and CD214B-B3100R. Verify that the alternative part number provides the appropriate voltage rating for the specific circuit requirements.
