Is there a KiCad symbol and footprint for the SS310?
Yes. The symbol is Diode:SS310 and the footprint Diode_SMD:D_SMA, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SS310?
SMA(DO-214AC), with 2 pins. Its footprint is drawn on this page.
Where is the SS310 datasheet?
MDD publishes it: the Datasheet link on this page opens it.
Where can I order the SS310?
JLCPCB lists it as part C15874, with 348,658 in stock; the sellers' links on this page open their listings.
What can replace the SS310?
Parts like it in the library: the SS310 by hongjiacheng, the SS510 by MDD, the SS510 by hongjiacheng and the SS510 by GOODWORK. Check their datasheets: a part that fits the footprint may still differ in its ratings.
