CDBA220-G

Overview

The CDBA220-G is a surface-mount Schottky Barrier Rectifier manufactured by Comchip Technology. It features a DO-214AC (SMA) package and is constructed using silicon epitaxial planar chips. The device is rated for a repetitive peak reverse voltage of 20V and an average forward rectified current of 2A. Key electrical characteristics include a low maximum DC forward voltage drop of 0.53V at 2A and a maximum reverse leakage current of 10µA at 20V. The component supports a non-repetitive peak forward surge current of 30A and operates within a junction temperature range of -65°C to +175°C.

Feature Summary

• Low forward voltage drop for improved efficiency in low-voltage applications
• High switching speed with minimal reverse recovery time
• ESD protection capability exceeding 15kV air discharge and 8kV contact discharge per IEC standards
• Lead-free construction compliant with RoHS directives

Applications

• Low voltage, high frequency inverters
• Free wheeling diode circuits
• Polarity protection systems

Procurement Notes

Verify the specific suffix and marking code on the physical component to ensure it matches the CDBA220-G designation exactly. Confirm that the datasheet revision aligns with the manufacturer's current documentation to avoid discrepancies in thermal or electrical ratings. Ensure the supplier provides traceability documentation for RoHS compliance and lead-free manufacturing processes as specified in the official product specifications.

Selection Notes

Select this component when a surface-mount Schottky rectifier is required for compact designs involving low input voltages. The 2A current rating and 20V breakdown voltage make it suitable for power management stages where minimizing conduction losses is critical. Consider the DO-214AC footprint constraints and the need for high-speed switching performance in digital signal or RF-related power circuits.

Part Context

This part belongs to the CDBA series of SMD Schottky Barrier Rectifiers from Comchip Technology. These devices are engineered for general-purpose rectification in space-constrained PCB layouts. The series utilizes silicon epitaxial planar technology to deliver consistent performance across varying thermal conditions while maintaining small form factors compatible with automated pick-and-place assembly processes.

Replacement Considerations

Cross-reference with other SMA-packaged Schottky diodes rated for 20V and 2A if sourcing constraints exist. Verify that any substitute maintains equivalent forward voltage and reverse leakage specifications to ensure circuit compatibility.
