Questions

Is there a KiCad symbol and footprint for the SMBJ40A?

Yes. 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?

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

Where can I order the SMBJ40A?

JLCPCB lists it as part C6937316, with 3,011 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 TDD, the SMBJ40CA by Guangdong Hottech, the SMBJ40A by TECH PUBLIC and the SMBJ40A by Shenzhen JDT Fuse. Check their datasheets: a part that fits the footprint may still differ in its ratings.
