Questions

Is there a KiCad symbol and footprint for the SMAJ18A?

Yes. The symbol is Diode:SMAJ18A and the footprint Diode_SMD:D_SMA, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the SMAJ18A?

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

Where can I order the SMAJ18A?

JLCPCB lists it as part C54318568, with 1,756 in stock; the sellers' links on this page open their listings.

What can replace the SMAJ18A?

Parts like it in the library: the SMAJ18CA-AT by Brightking, the SMA6J18CA by MDD, the SMAJ18A by Shenzhen JDT Fuse and the SMAJ18A by ShunYe. Check their datasheets: a part that fits the footprint may still differ in its ratings.
