Overview
The RBQ10BM45AFHTL is a silicon Schottky barrier diode manufactured by ROHM Semiconductor, designed for high-reliability applications. It features a dual anode common cathode configuration housed in a TO-252-3 (DPAK) surface-mount 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 of 50 A, and a maximum reverse current of 150 uA at 45 V. It operates within a junction temperature range up to +150 °C and holds AEC-Q101 qualification.
Feature Summary
- Dual anode common cathode configuration enables efficient bridge rectification in compact designs
- AEC-Q101 qualified for automotive-grade reliability and durability
- Low forward voltage drop contributes to reduced power loss and improved efficiency
- Surface-mount TO-252-3 package facilitates automated assembly and thermal management
Applications
- Automotive general-purpose rectification circuits
- DC-DC converter output rectification
- Free-wheeling diodes in inductive load switching
Procurement Notes
Verify the complete part number including the suffix to ensure correct packaging and tape-and-reel specifications. Confirm AEC-Q101 compliance requirements match the target application standards. Check for any specific handling instructions related to the surface-mount package during soldering processes. Ensure compatibility with existing PCB footprint dimensions for the TO-252-3 housing.
Selection Notes
Select this component when a low-voltage, high-current Schottky diode is required for automotive or industrial environments. The dual anode common cathode setup is suitable for full-wave rectification without requiring multiple discrete components. Consider the 45 V rating relative to system voltage peaks and the 10 A current capacity against thermal dissipation constraints in the chosen enclosure.
Part Context
This part belongs to ROHM's RBQ series of automotive-grade Schottky barrier diodes. The series is characterized by high reliability and low forward voltage, specifically engineered for demanding electronic systems. The RBQ10BM45AFHTL variant utilizes the BM package code for the DPAK form factor, distinguishing it from other series members with different current ratings or voltage thresholds.
Replacement Considerations
The RBR10BM45AFHTL is listed as a similar level replacement with the same pinout and package. Verify that the reverse recovery characteristics and specific forward voltage tolerances of the substitute meet the original circuit design requirements before implementation.
