Overview
The SMF18A is a TV made by TKS in a SOD-123FL package with 2 pins. -55℃~+150℃ 18V 1uA 200W@10/1000us 20V 29.2V 6.8A TVS Unidirectional SOD-123FL ESD and Surge Protection (TVS/ESD) ROHS.
PCBKit's library has its KiCad symbol (Diode:SMF18A, from KiCad's library) and its footprint (Diode_SMD:D_SMF, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C2760994).

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?
TKS publishes it: the Datasheet link on this page opens it.
Where can I order the SMF18A?
JLCPCB lists it as part C2760994, with 0 in stock; the sellers' links on this page open their listings.
What can replace the SMF18A?
Parts like it in the library: the SMF18A RQG by Taiwan Semiconductor, the SMF18A RVG by Taiwan Semiconductor, the UCLAMP1871P.TNT by SEMTECH and the SMCJ18CA by Boarden. Check their datasheets: a part that fits the footprint may still differ in its ratings.
