Is there a KiCad symbol and footprint for the BAT54A?
Yes. The symbol is Diode:BAT54A 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 BAT54A?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the BAT54A datasheet?
FMS publishes it: the Datasheet link on this page opens it.
Where can I order the BAT54A?
JLCPCB lists it as part C2926952, with 0 in stock; the sellers' links on this page open their listings.
What can replace the BAT54A?
Parts like it in the library: the BAT54SG by Galaxy Microelectronics, the BAT15-04R by Infineon Technologies, the BAT54S by JF and the BAT54SHE3-TP by Micro Commercial Components. Check their datasheets: a part that fits the footprint may still differ in its ratings.
