Questions

Is there a KiCad symbol and footprint for the SA18A?

Yes. The symbol is Device:D_TVS and the footprint EasyEDA_Cloud:DO-15_BD3.1-L6.7-P10.70-D0.8-FD, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the SA18A?

DO-15(DO-204AC), with 2 pins. Its footprint is drawn on this page.

Where is the SA18A datasheet?

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

Where can I order the SA18A?

JLCPCB lists it as part C1979085, with 3,970 in stock; the sellers' links on this page open their listings.

What can replace the SA18A?

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