Procurement Notes
Verify the specific ordering suffix against official ROHM documentation to confirm packaging details and availability status. Confirm that the component meets all required automotive qualification standards before integration into final designs. Ensure thermal management design accounts for the specified junction-to-case thermal resistance values under actual operating conditions.
Selection Notes
Select this component for applications requiring high-reliability dual Schottky configurations with ultra-low leakage currents. The TO-252 package provides efficient heat dissipation suitable for surface-mount assembly. Verify that the 30V reverse voltage rating aligns with the circuit's maximum operating voltage requirements and surge conditions.
