Is there a KiCad symbol and footprint for the SS420C?
Yes. The symbol is Device:D_Schottky and the footprint Diode_SMD:D_SMC, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SS420C?
SMC, with 2 pins. Its footprint is drawn on this page.
Where is the SS420C datasheet?
LGE publishes it: the Datasheet link on this page opens it.
Where can I order the SS420C?
JLCPCB lists it as part C330395, with 10,366 in stock; the sellers' links on this page open their listings.
What can replace the SS420C?
Parts like it in the library: the SS520C by hongjiacheng, the SS520-SMC by GOODWORK, the SS520 by LGE and the SS5200C by MDD. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the SS420C?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
