Is there a KiCad symbol and footprint for the BAP50-03?
Yes. The symbol is Device:D and the footprint Diode_SMD:D_SOD-323, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BAP50-03?
SOD-323, with 2 pins. Its footprint is drawn on this page.
Where is the BAP50-03 datasheet?
Jiangsu Changjing Electronics Technology (CJ) publishes it: the Datasheet link on this page opens it.
Where can I order the BAP50-03?
JLCPCB lists it as part C2991942, with 12,327 in stock; the sellers' links on this page open their listings.
What can replace the BAP50-03?
Parts like it in the library: the BAS321-QF by Nexperia, the BAS321-QX by Nexperia, the BAS321 by Nexperia and the BAP64-03 by Shikues. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the BAP50-03?
