RBQ20BGE45ATL

Overview

The RBQ20BGE45ATL is a silicon Schottky barrier diode manufactured by ROHM Semiconductor, housed in a TO-252 (D-Pak) surface-mount package. It features a dual anode common cathode configuration with a maximum repetitive reverse voltage of 45 V and an average rectified forward current rating of 20 A. The device exhibits a low forward voltage of 0.59 V at 10 A and a maximum reverse current of 0.2 mA at 45 V. It supports a forward surge current of 100 A and operates at junction temperatures up to +150 °C.

Feature Summary

• Dual anode common cathode configuration for efficient circuit design
• Low reverse leakage current characteristics
• High reliability power mold construction
• Surface mount compatibility via TO-252 package

Applications

• General purpose rectification in electronic circuits
• Power supply output stages
• Freewheeling diodes in switching applications

Procurement Notes

Verify the specific ordering suffix 'TL' against the manufacturer's official documentation to confirm tape and reel packaging specifications. Ensure the component meets RoHS compliance requirements for your target assembly process. Cross-reference the part number with the latest datasheet revision to confirm pinout and thermal characteristics match your PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when a compact surface-mount solution is required for 45 V applications needing 20 A continuous current. The TO-252 package offers a balance between thermal performance and board space efficiency compared to through-hole alternatives. Consider the low forward voltage drop for improved system efficiency in low-voltage power conversion designs where heat dissipation is a primary concern.

Part Context

This component belongs to the RBQ series of Schottky barrier diodes from ROHM Semiconductor, designed for high-reliability applications. The series includes variants with different voltage ratings and packages, such as the TO-220FN and D2PAK formats. The RBQ20BGE45ATL specifically targets general-purpose rectification needs within automotive and industrial electronics sectors requiring robust performance in a small footprint.

Replacement Considerations

Direct substitutes include the RBQ20NS45ATL (TO-263S package) and RBQ20BM45AFH (TO-252M package). Verify pinout compatibility and thermal resistance differences when replacing the TO-252 package with these alternatives. Ensure the replacement part maintains the same 45 V reverse voltage and 20 A current ratings for functional equivalence.
