Questions

Is there a KiCad symbol and footprint for the BAT42?

Yes. The symbol is Diode:BAT42 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 BAT42?

DO-35, with 2 pins. Its footprint is drawn on this page.

Where is the BAT42 datasheet?

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

Where can I order the BAT42?

JLCPCB lists it as part C2798198, with 4,061 in stock; the sellers' links on this page open their listings.

What can replace the BAT42?

Parts like it in the library: the BAT41KFILM by STMicroelectronics, the BAT46WJ by Nexperia, the BAT43W by hongjiacheng and the BAT42WS by hongjiacheng. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the BAT42?

57 boards in 42 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
