Procurement Notes
Verify the complete part number including the suffix against official ROHM documentation to ensure correct packaging and automotive grade compliance. Confirm that the specific revision matches the design requirements. Cross-reference the datasheet for exact thermal resistance values and mounting guidelines. Ensure the supplier provides traceability documents required for automotive quality standards. Check for any specific handling instructions related to the surface-mount technology.
Selection Notes
Select this component when a 65 V rating with 20 A continuous current capability is required in a D2PAK form factor. The low forward voltage makes it suitable for low-loss rectification in efficient power systems. The AEC-Q101 certification is essential for automotive electronics where long-term reliability and temperature stability are critical. Compare thermal performance against alternative packages if space constraints allow.
Part Context
This device belongs to ROHM's RBQ series of Schottky barrier diodes, which are engineered for high efficiency and reliability. The series covers various voltage ratings from 30 V to 100 V with currents up to 20 A. These diodes utilize silicon technology to achieve low leakage current and fast switching characteristics. The RBQ series is widely used in consumer, industrial, and automotive power management applications requiring robust rectification solutions.
Replacement Considerations
Direct substitutes may include other ROHM parts within the RBQ series with matching voltage and current ratings, such as RBQ20NS45ATL or RBQ20NS100AFH, provided the voltage rating aligns with the circuit design. Verify pinout compatibility and thermal characteristics before substitution.
