Questions

Is there a KiCad symbol and footprint for the SMA6F18A?

Yes. The symbol is Device:D_TVS and the footprint EasyEDA_Cloud:SMA_L4.3-W2.6-LS5.2-RD, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the SMA6F18A?

SMA-flat, with 2 pins. Its footprint is drawn on this page.

Where is the SMA6F18A datasheet?

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

Where can I order the SMA6F18A?

JLCPCB lists it as part C1975949, with 28 in stock; the sellers' links on this page open their listings.

What can replace the SMA6F18A?

Parts like it in the library: the SMA6F18A-M3 by Vishay Intertechnology, the SMF18CA by hongjiacheng, the SMAJ18A by GOODWORK and the SMAJ18CA by hongjiacheng. Check their datasheets: a part that fits the footprint may still differ in its ratings.
