- Video equipment power management
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required termination type, as variations exist within the series. Ensure that the procurement documentation explicitly states compliance with relevant environmental standards. Cross-reference the part number against official discontinuation notices to confirm availability status before finalizing orders.
Selection Notes
Select this component for applications requiring efficient rectification in space-constrained designs. The SMC package offers significant size reduction compared to competitive parts. Evaluate thermal management requirements based on the specified junction-to-lead thermal resistance. Consider the 50 V reverse voltage rating to ensure adequate margin for the target circuit's operating conditions.
Part Context
This component belongs to the CD214C-B3x series of Schottky Barrier Rectifiers designed for general-purpose rectification. The series covers reverse voltages from 20 V to 60 V while maintaining a consistent 3 A forward current rating across all variants. These devices are engineered to meet JEDEC standards for handling and reliability.
Replacement Considerations
The datasheet identifies the CD214C-B3xR Series as the recommended replacement for new designs. Verify pinout compatibility and electrical parameter alignment when substituting this component with the R-series variant.
