Overview
The BAT54 is a schottky Diode made by SMC in a SOT-523 package with 3 pins. 1 Independent 1V@100mA 200mA 2uA@25V 30V 600mA SOT-523 Schottky Diodes ROHS.
PCBKit's library has its KiCad symbol (dk_Diodes-Rectifiers-Single:BAT54_Obsolete, from Digikey) and its footprint (ICs And Semiconductors SMD:SOT95P240X130-3N, from CERN's library), ready for a KiCad board. JLCPCB lists it (part C3757910).

Is there a KiCad symbol and footprint for the BAT54?
Yes. The symbol is dk_Diodes-Rectifiers-Single:BAT54_Obsolete and the footprint ICs And Semiconductors SMD:SOT95P240X130-3N, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BAT54?
SOT-523, with 3 pins. Its footprint is drawn on this page.
Where is the BAT54 datasheet?
SMC publishes it: the Datasheet link on this page opens it.
Where can I order the BAT54?
JLCPCB lists it as part C3757910, with 0 in stock; the sellers' links on this page open their listings.
What can replace the BAT54?
Parts like it in the library: the HSMS-2820 by Broadcom Limited. Check their datasheets: a part that fits the footprint may still differ in its ratings.
