CGRB203-G

Single Diodes Overview

The CGRB203-G is a surface-mount general-purpose rectifier manufactured by Comchip Technology. It utilizes a glass-passivated silicon junction within an SMB (DO-214AA) package. The device supports a maximum repetitive peak reverse voltage of 200 V and an average forward current of 2 A. Key electrical characteristics include a maximum non-repetitive surge forward current of 60 A, a maximum DC reverse current of 5 uA at rated voltage, and a maximum instantaneous forward voltage of 1.1 V. The component operates reliably across a temperature range from -55 °C to +150 °C.

Single Diodes Feature Summary

• Glass-passivated silicon junction for enhanced stability and reliability
• SMB (DO-214AA) surface-mount package designed for automated pick-and-place assembly
• High surge current capability with built-in strain relief in the plastic molding

Single Diodes Applications

• General-purpose rectification in surface-mount power supply circuits
• Reverse polarity protection in electronic assemblies
• DC output rectification in consumer electronics

Single Diodes Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm compliance status and exact electrical tolerances. Ensure the ordering part number matches the required voltage and current ratings for the target application. Confirm RoHS directive adherence through the supplier's declaration of conformity prior to procurement.

Single Diodes Selection Notes

Select this component when a standard recovery rectifier is required in an SMB package. The 200 V rating suits low-voltage AC-to-DC conversion applications. Verify that the PCB footprint aligns with JEDEC DO-214AA dimensions. Consider the thermal resistance and ambient operating conditions to ensure the junction temperature remains within the specified limits during operation.

Single Diodes Part Context

This component belongs to the CGRB series of surface-mount general-purpose rectifiers produced by Comchip Technology. The series offers various voltage ratings while maintaining a consistent 2 A forward current capacity and SMB package form factor. This family is designed to replace bulkier axial-leaded equivalents in modern compact electronic designs.

Single Diodes Replacement Considerations

Direct substitutes include other SMB-packaged 200 V, 2 A general-purpose rectifiers such as the MBR20100 or equivalent parts from other manufacturers. Verify pinout compatibility and thermal performance before substitution.
