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 C55222913, with 5,000 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.
