Is there a KiCad symbol and footprint for the SMBJ18CA?
Yes. The symbol is Diodes:Diode TVS Bi-Directional and the footprint Diode_SMD:D_SMB, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SMBJ18CA?
SMB, with 2 pins. Its footprint is drawn on this page.
Where can I order the SMBJ18CA?
JLCPCB lists it as part C53133595, with 2,402 in stock; the sellers' links on this page open their listings.
What can replace the SMBJ18CA?
Parts like it in the library: the SMBJ18A by TECH PUBLIC, the SMBJ18A by PDW, the SMBJ18A by Shenzhen JDT Fuse and the SMBJ18A by SPSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
