Questions

Is there a KiCad symbol and footprint for the SMBJ54A?

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 SMBJ54A?

DO-214AA(SMB), with 2 pins. Its footprint is drawn on this page.

Where is the SMBJ54A datasheet?

MDD publishes it: the Datasheet link on this page opens it.

Where can I order the SMBJ54A?

JLCPCB lists it as part C123823, with 1,906 in stock; the sellers' links on this page open their listings.

What can replace the SMBJ54A?

Parts like it in the library: the SMBJ54A by BORN, the SMBJ54CA by BORN, the SMBJ54CA/TR13 by Brightking and the SMBJ54A by DOWO. Check their datasheets: a part that fits the footprint may still differ in its ratings.
