Questions

Is there a KiCad symbol and footprint for the BAT54CL?

Yes. The symbol is Diode:BAT54C 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 BAT54CL?

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

Where is the BAT54CL datasheet?

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

Where can I order the BAT54CL?

JLCPCB lists it as part C14308, with 153,014 in stock; the sellers' links on this page open their listings.

What can replace the BAT54CL?

Parts like it in the library: the BAT54S by MDD, the BAT54S by hongjiacheng, the BAT54S by JSMSEMI and the BAT54S,215 by Nexperia. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the BAT54CL?

2 boards in 2 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
