Overview
The RBQ10BM45ATL is a surface-mount Schottky barrier diode manufactured by ROHM Semiconductor. It features a dual anode common cathode configuration within a TO-252 (DPAK) package. The device supports a maximum repetitive reverse voltage of 45 V and an average rectified forward current of 10 A. Key electrical parameters include a maximum forward voltage of 650 mV at 5 A, a peak forward surge current capability of 50 A, and a maximum reverse current of 70 µA at 45 V. The component operates with a maximum junction temperature of +150 °C and complies with the AEC-Q101 automotive reliability standard.
Feature Summary
- Dual anode common cathode configuration for flexible circuit integration
- Automotive-grade reliability compliant with AEC-Q101 standards
- Low forward voltage characteristic to minimize conduction losses
- High thermal stability supporting operation up to 150 °C junction temperature
Applications
- General purpose rectification in automotive electronic systems
- DC-DC converter output stages
- Free-wheeling diodes in power supply circuits
Procurement Notes
Verify the specific suffix 'ATL' against the official ROHM datasheet to confirm tape-and-reel packaging details and quantity per reel. Ensure the ordering code matches the required automotive grade specifications. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability and lead times prior to finalizing procurement orders.
Selection Notes
Select this component when a compact surface-mount solution is required for 45 V applications. The TO-252 package offers a balance between current handling capacity and board space efficiency. Consider the AEC-Q101 qualification if the design targets automotive environments. Evaluate the thermal resistance characteristics of the PCB layout to ensure the junction temperature remains within the specified 150 °C limit under continuous load conditions.
Part Context
This device belongs to the RBQ series of high-reliability Schottky barrier diodes designed by ROHM Semiconductor. The series utilizes silicon technology to provide low leakage current and fast switching performance. The RBQ10BM45 variant specifically addresses the needs for efficient power conversion in constrained spaces, offering a robust alternative to traditional rectifiers in modern electronic designs.
Replacement Considerations
Direct substitutes include the RBQ10BM45AFH and RBQ10BGE45A. Verify that replacement parts maintain the same TO-252 footprint and pinout compatibility. Confirm that the alternative device meets or exceeds the 45 V reverse voltage and 10 A current ratings. Ensure any substitute also satisfies the specific AEC-Q101 requirements if automotive compliance is mandatory.
