Questions

Is there a KiCad symbol and footprint for the SMF18A?

Yes. The symbol is Diode:SMF18A 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 SMF18A?

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

Where is the SMF18A datasheet?

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

Where can I order the SMF18A?

JLCPCB lists it as part C7439202, with 2,543 in stock; the sellers' links on this page open their listings.

What can replace the SMF18A?

Parts like it in the library: the SMF18A by YTL, the SMF18A by baocheng, the SMF18A by TDD and the SMF18A by Zhengxin. Check their datasheets: a part that fits the footprint may still differ in its ratings.
