Questions

Is there a KiCad symbol and footprint for the SS12?

Yes. The symbol is Diode:SS12 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 SS12?

SMA(DO-214AC), with 2 pins. Its footprint is drawn on this page.

Where is the SS12 datasheet?

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

Where can I order the SS12?

JLCPCB lists it as part C2479, with 90,271 in stock; the sellers' links on this page open their listings.

What can replace the SS12?

Parts like it in the library: the SS34 by MDD, the SS14 by MDD, the SS54 by MDD and the SS54 by hongjiacheng. Check their datasheets: a part that fits the footprint may still differ in its ratings.
