Questions

Is there a KiCad symbol and footprint for the BAT54S?

Yes. The symbol is Diode:BAT54S and the footprint Package_TO_SOT_SMD:SOT-23, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the BAT54S?

SOT-23, with 3 pins. Its footprint is drawn on this page.

Where is the BAT54S datasheet?

Diodes Incorporated publishes it: the Datasheet link on this page opens it.

Where can I order the BAT54S?

JLCPCB lists it as part C83574, with 4 in stock; the sellers' links on this page open their listings.

What can replace the BAT54S?

Parts like it in the library: the BAT54S by MDD, the BAT54S by hongjiacheng, the BAT54S by GOODWORK and the BAT54S by SEP. Check their datasheets: a part that fits the footprint may still differ in its ratings.
