Procurement Notes

Verify the complete part number including the suffix HTL to ensure correct packaging configuration. Confirm AEC-Q101 compliance requirements match specific automotive design specifications. Check RoHS and REACH SVHC status against current environmental regulations. Ensure thermal management solutions accommodate the specified maximum junction temperature limits during operation.

Selection Notes

Select this component when a 60 V rating with 20 A continuous current capacity is required in a D2PAK package. Consider the forward voltage drop and reverse leakage current specifications for thermal budget calculations. Evaluate the dual common cathode configuration against single-diode alternatives for circuit topology compatibility. Verify that the surface-mount footprint aligns with existing PCB layout constraints.

Part Context

This device belongs to ROHM's RBR series of automotive Schottky barrier diodes. The series emphasizes high reliability and low forward voltage for automotive power management. The TO-263S package provides a balance between current handling capability and board space efficiency. Similar parts in the lineup vary primarily in voltage ratings and current capacities while maintaining consistent packaging and automotive qualification standards.

Replacement Considerations

Cross-reference with RBQ20NS65AFHTL for higher voltage tolerance or RBR40NS60AFHTL for increased current capacity. Ensure pinout compatibility and thermal resistance characteristics match the original design requirements before substitution.
