Questions

Is there a KiCad symbol and footprint for the SMF18CA?

Yes. The symbol is Device:D_TVS and the footprint Diode_SMD:D_SOD-123, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the SMF18CA?

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

Where is the SMF18CA datasheet?

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

Where can I order the SMF18CA?

JLCPCB lists it as part C188308, with 0 in stock; the sellers' links on this page open their listings.

What can replace the SMF18CA?

Parts like it in the library: the SMF18CA by AnBon, the SMF18CA by PTTC, the SMF18CA-Q1 by AnBon and the SMF18CA by SOCAY Elec. Check their datasheets: a part that fits the footprint may still differ in its ratings.
