Procurement Notes
Verify the specific part number against official manufacturer documentation to confirm availability status and compliance with current environmental directives. Ensure that the selected component meets the required electrical ratings for the intended application environment. Cross-reference datasheet specifications with actual operating conditions before procurement.
Selection Notes
Select this component based on its 20 V reverse voltage rating and 3 A forward current capacity. Consider the low forward voltage drop for efficiency in high-frequency applications. Verify compatibility with standard pick-and-place equipment due to the flat SMB package configuration. Evaluate thermal management requirements relative to the specified junction-to-ambient thermal resistance.
Part Context
This component belongs to the CD214B-B3xR series of Schottky Barrier Rectifier Chip Diodes from Bourns. The series provides silicon diodes with minimal packaging overhead, designed for compact chip packages compatible with DO-214AA formats. These devices are engineered to support the miniaturization trends in portable communications, computing, and video equipment manufacturing.
Replacement Considerations
Consult the official Bourns selector guide for alternative part numbers within the CD214B-B3xR series or other compatible Schottky rectifier families. Verify pinout compatibility and electrical parameter equivalence before substituting.
