Single Diodes Procurement Notes

Verify the specific ordering suffix and packaging configuration against official Rohm documentation before procurement. Confirm that the component meets all required automotive or industrial standards if applicable, as this model is designated for standard-grade use rather than automotive qualification. Ensure compatibility with the intended PCB footprint and reflow soldering profile.

Single Diodes Selection Notes

Select this component for designs requiring fast switching speeds and low conduction losses in general-purpose rectification tasks. The TO-277GE package offers robust surface-mount reliability. Consider the 200V rating and 4A current capacity when sizing for load requirements. Note that this part is not recommended for automotive equipment; choose alternative qualified parts for such applications.
