Is there a KiCad symbol and footprint for the SMBJ18A?
Yes. The symbol is Device:D_TVS 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 SMBJ18A?
DO-214AA, with 2 pins. Its footprint is drawn on this page.
Where is the SMBJ18A datasheet?
SURGING publishes it: the Datasheet link on this page opens it.
Where can I order the SMBJ18A?
JLCPCB lists it as part C7470944, with 7,611 in stock; the sellers' links on this page open their listings.
What can replace the SMBJ18A?
Parts like it in the library: the SMBJ18CA/TR13 by Brightking, the SMBJ18CA by hongjiacheng, the SMBJ18A by Shandong Jingdao Microelectronics and the SMBJ18CA by MDD. Check their datasheets: a part that fits the footprint may still differ in its ratings.
