CDBC220LR-HF

Overview

The CDBC220LR-HF is a surface-mount Schottky barrier rectifier manufactured by Comchip Technology. It features a 20V maximum repetitive reverse voltage and a 2A average forward current rating. The device utilizes an SMC (DO-214AB) package for efficient thermal dissipation. Key electrical characteristics include low forward voltage drop and low reverse leakage current, optimized for high-efficiency power conversion applications.

Feature Summary

• Low forward voltage drop for enhanced efficiency
• Low reverse leakage current
• High surge current capability
• Ultra-fast switching performance

Applications

• DC-DC converters
• Power supply circuits
• Free-wheeling diodes in inductive loads
• Polarity protection circuits

Procurement Notes

Verify the specific suffix 'LR' against official Comchip documentation to confirm it denotes Low Forward Voltage and Low Leakage variants, as standard part numbers may differ. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to ordering.

Selection Notes

Select this component when a compact SMC package is required for 2A applications with strict voltage limits of 20V. Ensure the design accounts for the thermal resistance of the SMC footprint. Compare forward voltage specifications against standard CDBC series parts if lower loss is critical.

Part Context

This part belongs to Comchip's SMD Schottky Barrier Rectifier lineup. It is designed for general-purpose rectification in low-voltage, high-current environments. The SMC package offers superior heat dissipation compared to smaller packages like SMA or SMB, supporting higher continuous current ratings.

Replacement Considerations

Check datasheets for equivalent 20V 2A SMC Schottky diodes from other manufacturers. Verify pinout compatibility and thermal characteristics before substituting.
