Questions

Is there a KiCad symbol and footprint for the SMCJ18A?

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

What package is the SMCJ18A?

DO-214AB(SMC), with 2 pins. Its footprint is drawn on this page.

Where is the SMCJ18A datasheet?

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

Where can I order the SMCJ18A?

JLCPCB lists it as part C840765, with 2,413 in stock; the sellers' links on this page open their listings.

What can replace the SMCJ18A?

Parts like it in the library: the SMCJ18CA by Shandong Jingdao Microelectronics, the SMCJ18A by BORN, the SMCJ18CA by hongjiacheng and the 5.0SMDJ18CA by BORN. Check their datasheets: a part that fits the footprint may still differ in its ratings.
