Procurement Notes
This component is officially marked as obsolete by the manufacturer and is not recommended for new designs. Verify availability through secondary market channels or distributors holding existing stock. Confirm that the specific lot date code meets project requirements before procurement. Evaluate alternative replacement products provided by the manufacturer to ensure long-term supply chain stability and compliance with current design standards.
Selection Notes
Select this component only for legacy system maintenance or repair where original specifications must be strictly maintained. Ensure the PCB footprint matches the DO-214AA (SMB) dimensions. Verify that the circuit can accommodate the 1000 V reverse voltage rating and 3.0 A continuous current limits. Consider derating curves for ambient temperature conditions exceeding standard ratings during operation.
Part Context
The CD214B-R3100 belongs to the CD214B-R350~R31000 series of glass passivated rectifiers manufactured by Bourns Inc. This series offers various voltage ratings from 50 V to 1000 V within the compact SMB package format. The components conform to JEDEC standards and are designed for automated placement on standard pick-and-place equipment due to their flat configuration.
Replacement Considerations
The datasheet states the series is obsolete and recommends replacement products are available. Consult official Bourns documentation for specific cross-reference part numbers suitable for redesigning out this obsolete component.
