Is there a KiCad symbol and footprint for the SK32?
Yes. The symbol is Device:D_Schottky and the footprint Diode_SMD:D_SMB, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SK32?
SMB, with 2 pins. Its footprint is drawn on this page.
Where can I order the SK32?
JLCPCB lists it as part C51909053, with 2,424 in stock; the sellers' links on this page open their listings.
What can replace the SK32?
Parts like it in the library: the SS510B by hongjiacheng, the SS54B by hongjiacheng, the SS56B by hongjiacheng and the SS34 by MDD. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the SK32?
4 boards in 3 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
