Questions

Is there a KiCad symbol and footprint for the SMBJ45A?

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 SMBJ45A?

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

Where is the SMBJ45A datasheet?

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

Where can I order the SMBJ45A?

JLCPCB lists it as part C6937320, with 162 in stock; the sellers' links on this page open their listings.

What can replace the SMBJ45A?

Parts like it in the library: the SMBJ45A by TECH PUBLIC, the SMBJ45CA by PDW, the SMBJ45A MV-TD by TDSEMIC and the SMBJ45CA CV-TD by TDSEMIC. Check their datasheets: a part that fits the footprint may still differ in its ratings.
