Is there a KiCad symbol and footprint for the SM4F18A-TP?
Yes. The symbol is Device:D_TVS and the footprint Diode_SMD:D_SOD-123F, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SM4F18A-TP?
SOD-123FL, with 2 pins. Its footprint is drawn on this page.
Where is the SM4F18A-TP datasheet?
Micro Commercial Components publishes it: the Datasheet link on this page opens it.
Where can I order the SM4F18A-TP?
JLCPCB lists it as part C725473, with 0 in stock; the sellers' links on this page open their listings.
What can replace the SM4F18A-TP?
Parts like it in the library: the UCLAMP1871P.TNT by SEMTECH, the SMCJ18CA by Boarden, the TVS318 by Microchip Technology and the SMAJ18A-QH by Bourns. Check their datasheets: a part that fits the footprint may still differ in its ratings.
