Questions

Is there a KiCad symbol and footprint for the SMBJ40A?

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 SMBJ40A?

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

Where is the SMBJ40A datasheet?

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

Where can I order the SMBJ40A?

JLCPCB lists it as part C5860943, with 2,880 in stock; the sellers' links on this page open their listings.

What can replace the SMBJ40A?

Parts like it in the library: the SMBJ40CA by Brightking, the SMBJ40CA by MDD, the SMBJ40A by MDD and the SMBJ40CA by hongjiacheng. Check their datasheets: a part that fits the footprint may still differ in its ratings.
