Is there a KiCad symbol and footprint for the SD12C?
Yes. The symbol is Device:D_TVS and the footprint Diode_SMD:D_SOD-323, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SD12C?
SOD-323, with 2 pins. Its footprint is drawn on this page.
Where is the SD12C datasheet?
UMW publishes it: the Datasheet link on this page opens it.
Where can I order the SD12C?
JLCPCB lists it as part C2833281, with 1,091 in stock; the sellers' links on this page open their listings.
What can replace the SD12C?
Parts like it in the library: the GBLC12C by MDD, the CESD12VD3 by Jiangsu Changjing Electronics Technology (CJ), the H12VHD3UA by hongjiacheng and the H12VSD3B by hongjiacheng. Check their datasheets: a part that fits the footprint may still differ in its ratings.
