Questions

Is there a KiCad symbol and footprint for the ST54B?

Yes. The symbol is Device:D_Schottky 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 ST54B?

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

Where is the ST54B datasheet?

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

Where can I order the ST54B?

JLCPCB lists it as part C414002, with 0 in stock; the sellers' links on this page open their listings.

What can replace the ST54B?

Parts like it in the library: the SS510B by hongjiacheng, the SS54B by hongjiacheng, the SS56B by hongjiacheng and the SS56B by MDD. Check their datasheets: a part that fits the footprint may still differ in its ratings.
