CDBER54

Overview

The CDBER54 is a silicon Schottky barrier rectifier diode manufactured by Comchip Technology. It features a single-element, one-phase configuration housed in an SOD-723F (0503) surface-mount package. The device is rated for a maximum repetitive reverse voltage of 30V and an average forward rectified current of 200mA. Key electrical characteristics include a low forward voltage drop and fast switching capabilities, making it suitable for high-frequency applications.

Feature Summary

• Schottky barrier construction for low forward voltage and fast switching
• Guard ring design provides protection against transient voltages and ESD
• Utilizes gold termination technology to ensure zero tin-whisker potential

Applications

• High-frequency rectification in power supplies
• DC-DC converter circuits
• Polarity protection in electronic systems

Procurement Notes

Verify the specific ordering suffix when sourcing components. Confirm that the received part matches the exact model designation and package type specified in the design requirements. Ensure compliance with RoHS standards if required by the application specifications.

Selection Notes

Select this component for applications requiring low forward voltage drop and rapid switching speeds within a compact surface-mount footprint. Consider the 30V reverse voltage rating and 200mA current capacity to ensure adequate headroom for the target circuit operation.

Part Context

Comchip Technology specializes in surface-mount discrete semiconductors, including Schottky diodes and rectifiers. The company utilizes patented flat chip manufacturing processes and gold termination techniques to enhance reliability and solderability while eliminating tin whisker risks in their DFN and small outline packages.

Replacement Considerations

BAS54 is a documented alternative from Comchip Technology offering similar 30V and 200mA ratings. Verify pinout compatibility and thermal performance before substituting.
