Is there a KiCad symbol and footprint for the BAT54L?
Yes. The symbol is Device:D_Schottky and the footprint EasyEDA_Cloud:DFN1006-2L-RD, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BAT54L?
DFN1006-2, with 2 pins. Its footprint is drawn on this page.
Where is the BAT54L datasheet?
Nexperia publishes it: the Datasheet link on this page opens it.
Where can I order the BAT54L?
JLCPCB lists it as part C549279, with 112,886 in stock; the sellers' links on this page open their listings.
What can replace the BAT54L?
Parts like it in the library: the WSB5546N-2/TR by WILLSEMI, the PMEG4010ESBYL by Nexperia, the PSBD2FD40V1H by Shanghai Prisemi Elec and the PMEG4010ESBYL-FS by FUXINSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the BAT54L?
7 boards in 5 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
