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?
ZHIDE publishes it: the Datasheet link on this page opens it.
Where can I order the SMF28A?
JLCPCB lists it as part C5161232, with 2,966 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 hongjiacheng, the SMF28A by JSMSEMI, the SMF28A by MDD and the SMF28A by Shandong Jingdao Microelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
