Questions

Is there a KiCad symbol and footprint for the SMBJ33A?

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 SMBJ33A?

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

Where is the SMBJ33A datasheet?

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

Where can I order the SMBJ33A?

JLCPCB lists it as part C5334028, with 2,710 in stock; the sellers' links on this page open their listings.

What can replace the SMBJ33A?

Parts like it in the library: the SMBJ33CA by hongjiacheng, the SMBJ33CA by Brightking, the SMBJ33A by hongjiacheng and the SMBJ33CA by MDD. Check their datasheets: a part that fits the footprint may still differ in its ratings.
