Procurement Notes

Verify the specific suffix against official ROHM documentation to confirm package type and qualification status. Ensure compatibility with existing PCB footprints for the SOT-416 form factor. Confirm that the component meets required automotive reliability standards if used in safety-critical systems. Check for any obsolescence notices or lifecycle changes directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a compact NPN digital transistor with integrated pull-up and pull-down resistors is required. The 4.7 kΩ input resistance suits standard logic interfaces. Consider the 50 V rating for low-voltage switching applications. Verify that the 100 mA current capacity meets load requirements. The AEC-Q101 qualification makes it suitable for automotive environments requiring extended temperature ranges.
