RBR10BGE40ATL

Overview

The RBR10BGE40ATL is a standard-grade Schottky barrier diode manufactured by ROHM Semiconductor. It features a common cathode configuration within a TO-252AA (D-Pak) surface-mount package. Key electrical parameters include a maximum repetitive reverse voltage of 40V and an average rectified forward current rating of 10A. The device exhibits a low forward voltage drop, with a maximum value of 0.62V at 5A. It supports a maximum junction temperature of 150°C and operates within a storage temperature range of -55°C to 150°C. The component is RoHS compliant and supplied in tape-and-reel packaging.

Feature Summary

• Low forward voltage characteristic for improved efficiency
• Common cathode dual-diode configuration
• High thermal stability with 150°C junction temperature rating

Applications

• Switching power supply circuits
• DC-DC converter freewheeling applications
• General-purpose rectification in consumer electronics

Procurement Notes

Verify the specific suffix 'TL' against official ROHM documentation to confirm tape-and-reel quantity and orientation. Confirm that the application does not require automotive qualification, as this standard-grade part is explicitly noted as unsuitable for vehicle equipment. Ensure the design accounts for the 10A continuous current limit and thermal dissipation requirements inherent to the D-Pak package.

Selection Notes

Select this component when a high-current, low-voltage drop solution is required for non-automotive power management. The common cathode arrangement allows for use in full-wave rectification or synchronous rectification topologies without requiring separate components. Consider the TO-252AA footprint compatibility during PCB layout. Evaluate thermal performance under peak load conditions to ensure the junction temperature remains within the specified 150°C limit.

Part Context

This device belongs to the RBR10 series of Schottky barrier diodes from ROHM Semiconductor. The series is designed for general-purpose power applications where low forward voltage and high current handling are prioritized. Unlike the AEC-Q101 qualified variants in the same family, this standard-grade version focuses on cost-effective performance for industrial and consumer markets rather than automotive reliability standards.

Replacement Considerations

Direct substitutes must match the 40V/10A rating, common cathode configuration, and TO-252AA package. Verify equivalent forward voltage and reverse leakage characteristics. Note that automotive-grade equivalents like the RBR10LAM series require additional qualification verification.
