Procurement Notes

Verify the specific ordering suffix and package variant against the official ROHM datasheet to ensure compatibility with your PCB footprint. Confirm that the AEC-Q101 qualification meets your project's automotive grade requirements. Check for any recent lifecycle status updates or recommended replacement parts from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a dual Schottky diode configuration is required in a small SMD package. Ensure the 30 V reverse voltage and 0.1 A current ratings align with your circuit's peak operating conditions. Consider the thermal management capabilities given the 125 °C junction temperature limit and the physical dimensions of the EMD4 package.
