Procurement Notes
Verify component authenticity through authorized Bourns distributors or official channels. Confirm that the received parts match the specified DO-214AB package dimensions and marking codes. Ensure storage conditions comply with moisture sensitivity level requirements prior to surface mount assembly processes.
Selection Notes
Select this component for applications requiring compact SMC packaging with a 3 A continuous current rating. The 20 V reverse voltage specification suits low-voltage rectification tasks. Evaluate thermal resistance parameters against system heat dissipation capabilities to ensure reliable operation within the specified temperature limits.
Part Context
This part belongs to the CD214C-B3xR series of Schottky Barrier Rectifier Chip Diodes designed for portable communications, computing, and video equipment. The series addresses industry demands for smaller electronic components by offering silicon diodes in minimal packaging overhead formats compatible with standard surface mount equipment.
Replacement Considerations
Cross-reference with other Bourns CD214C-B3xR variants sharing identical 3 A ratings but differing reverse voltages. Verify pinout compatibility and physical footprint alignment before substituting.
