CDBB280-G

Overview

The CDBB280-G is a single-phase full-wave Schottky bridge rectifier manufactured by Comchip Technology. It features a silicon epitaxial planar chip construction with a metal-silicon junction, designed for low power loss and high efficiency. The device operates with a maximum repetitive reverse voltage of 100V and provides a continuous output current of 2A. It exhibits a low forward voltage drop of 0.85V and supports a non-repetitive peak forward surge current of 50A. The component is housed in an SO-4 surface-mount package (R-PDSO-G4) and functions reliably within a temperature range of -55°C to 125°C.

Feature Summary

• Utilizes batch process design for excellent power dissipation and thermal resistance

• Includes free-wheeling diode capability for overvoltage protection
• Constructed with silicon epitaxial planar chips for robust performance

Applications

• Low profile surface mounted applications optimizing board space
• General purpose rectification in electronic circuits
• Free-wheeling diode configurations
• Overvoltage protection guarding

Procurement Notes

Verify the specific ordering suffix against official Comchip Technology documentation to ensure correct configuration. Confirm RoHS compliance status and lead-free manufacturing standards as required by project specifications. Cross-reference the package marking code with datasheet images to prevent substitution errors during assembly.

Selection Notes

Select this component for designs requiring a compact Schottky bridge rectifier with low forward voltage characteristics. Ensure the application current remains within the 2A continuous limit and that peak surge currents do not exceed 50A. Verify that the operating environment stays within the specified -55°C to 125°C temperature range for reliable operation.

Part Context

This part belongs to the CDBB series of Schottky barrier rectifiers from Comchip Technology. The series is characterized by its low profile package, which is significantly thinner than standard alternatives, making it suitable for space-constrained surface mount designs. The technology leverages silicon epitaxial planar chips to deliver high current capability and fast switching speeds.

Replacement Considerations

Consult official manufacturer cross-reference lists for verified substitutes. Ensure any replacement maintains the same 100V reverse voltage rating, 2A current capacity, and SO-4 package footprint to guarantee mechanical and electrical compatibility.
