Questions

Is there a KiCad symbol and footprint for the SMBJ18A?

Yes. The symbol is Device:D_TVS and the footprint ICs And Semiconductors SMD:DIOM5336X265N, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the SMBJ18A?

SMBG, with 2 pins. Its footprint is drawn on this page.

Where is the SMBJ18A datasheet?

Jiangsu Changjing Electronics Technology (CJ) publishes it: the Datasheet link on this page opens it.

Where can I order the SMBJ18A?

JLCPCB lists it as part C5294277, with 210 in stock; the sellers' links on this page open their listings.

What can replace the SMBJ18A?

Parts like it in the library: the SMBJ18CA by High Diode, 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.
