Procurement Notes
Verify the specific part number against official manufacturer documentation to ensure correct voltage and current ratings. Confirm that the RoHS compliance status matches current regulatory requirements for your region. Check for any updates to the datasheet regarding absolute maximum ratings or thermal resistance values before finalizing procurement specifications.
Selection Notes
Select this component when a 3 A forward current capacity and 40 V reverse voltage rating are required in a surface-mount format. Consider the DO-214AB compatible footprint for PCB layout compatibility. Evaluate the thermal performance based on the specified junction-to-ambient thermal resistance under your specific mounting conditions.
Part Context
This component belongs to the CD214C-B3xR series of Schottky Barrier Rectifiers from Bourns. The series offers various voltage options ranging from 20 V to 100 V while maintaining a consistent 3 A current rating. These diodes are designed for miniaturization trends in portable communications, computing, and video equipment markets.
Replacement Considerations
Compatible substitutes within the same series include CD214C-B320R (20 V), CD214C-B360R (60 V), and CD214C-B3100R (100 V). Ensure the replacement maintains the required reverse voltage margin for the specific application circuit.
