Questions

Is there a KiCad symbol and footprint for the SMF28AH?

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 SMF28AH?

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

Where can I order the SMF28AH?

JLCPCB lists it as part C55020836, with 2,643 in stock; the sellers' links on this page open their listings.

What can replace the SMF28AH?

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