Is there a KiCad symbol and footprint for the BAT41?
Yes. The symbol is Diode:BAT41 and the footprint Diode_THT:D_DO-35_SOD27_P7.62mm_Horizontal, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BAT41?
DO-35, with 2 pins. Its footprint is drawn on this page.
Where is the BAT41 datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the BAT41?
JLCPCB lists it as part C2969790, with 1,109 in stock; the sellers' links on this page open their listings.
What can replace the BAT41?
Parts like it in the library: the BAT46W by hongjiacheng, the BAT46WS by hongjiacheng, the BAT46WS by Jiangsu Changjing Electronics Technology (CJ) and the BAT46X by hongjiacheng. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the BAT41?
48 boards in 16 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
