Is there a KiCad symbol and footprint for the BAT54AL?
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 BAT54AL?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the BAT54AL datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the BAT54AL?
JLCPCB lists it as part C92068, with 135,807 in stock; the sellers' links on this page open their listings.
What can replace the BAT54AL?
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 BAT54AL?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
