Questions

Is there a KiCad symbol and footprint for the SMF28A?

Yes. The symbol is Diode:SMF28A and the footprint Diode_SMD:D_SMF, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the SMF28A?

SOD-123FL, with 2 pins. Its footprint is drawn on this page.

Where is the SMF28A datasheet?

RealChip publishes it: the Datasheet link on this page opens it.

Where can I order the SMF28A?

JLCPCB lists it as part C6937190, with 213 in stock; the sellers' links on this page open their listings.

What can replace the SMF28A?

Parts like it in the library: the SMF28A by YTL, the SMF28A by baocheng, the SMF28A by High Diode and the SMF28AH by MDD. Check their datasheets: a part that fits the footprint may still differ in its ratings.
