Questions

Is there a KiCad symbol and footprint for the MSMBJ51A?

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 MSMBJ51A?

DO-214AA(SMBJ), with 2 pins. Its footprint is drawn on this page.

Where can I order the MSMBJ51A?

JLCPCB lists it as part C2624292, with 0 in stock; the sellers' links on this page open their listings.

What can replace the MSMBJ51A?

Parts like it in the library: the SMBJ51CA by hongjiacheng, the SMBJ51CA by BORN, the SMBJ51CA by DOWO and the SMBJ51A by FOSAN. Check their datasheets: a part that fits the footprint may still differ in its ratings.
