Overview
The RBQ10NS45AFHTL is a silicon Schottky barrier diode manufactured by ROHM Semiconductor, housed in a TO-263S (D2PAK) 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 of 10 A. The device exhibits a maximum forward voltage of 550 mV at 5 A and a low reverse leakage current of 5 uA at 45 V. It supports a non-repetitive peak forward surge current of 50 A and operates at junction temperatures up to +150 °C. This component holds AEC-Q101 qualification for automotive reliability.
Feature Summary
- Dual anode common cathode configuration for efficient circuit design
- Low forward voltage drop to minimize power loss
- High thermal stability supporting elevated operating temperatures
- Automotive-grade reliability certified under AEC-Q101 standards
Applications
- General purpose rectification in automotive electronics
- DC-DC converter output stages
- Free-wheeling diodes in inductive load circuits
Procurement Notes
Verify the complete part number including the suffix to ensure correct packaging and tape specifications. Confirm that the required AEC-Q101 automotive qualification aligns with your system's reliability standards. Check the datasheet for specific thermal resistance values relevant to your PCB layout. Ensure the TO-263S footprint matches your design constraints before finalizing procurement.
Selection Notes
Select this component when a 45 V rating and 10 A continuous current capacity are required in a D2PAK package. The dual common cathode structure allows for use in full-wave rectification or synchronous rectification applications without requiring separate components. Consider the low reverse leakage current for efficiency-sensitive designs. Verify that the 150 °C maximum junction temperature meets the thermal management requirements of the target application environment.
Part Context
This part belongs to ROHM's RBQ series of high-efficiency, high-reliability Schottky barrier diodes designed specifically for automotive applications. The series offers various voltage and current ratings within standardized packages to simplify supply chain management. The RBQ10NS45AFHTL represents a mid-range option balancing voltage withstand capability with moderate current handling in a robust surface-mount form factor suitable for automated assembly.
Replacement Considerations
The RBQ10NS45AFH is listed as an alias for this component. Verify pinout compatibility and electrical parameters against the official datasheet before substitution. No other specific substitute part numbers are confirmed in the provided documentation.
