Questions

Is there a KiCad symbol and footprint for the SMBJ48A?

Yes. The symbol is Diodes:Diode TVS Uni-Directional 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 SMBJ48A?

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

Where can I order the SMBJ48A?

JLCPCB lists it as part C53278473, with 5,825 in stock; the sellers' links on this page open their listings.

What can replace the SMBJ48A?

Parts like it in the library: the SMBJ48A by hongjiacheng, the SMBJ48A by TDD, the SMBJ48A by YFW and the SMBJ48A by Zhengxin. Check their datasheets: a part that fits the footprint may still differ in its ratings.
