Is there a KiCad symbol and footprint for the SMF12A?
Yes. The symbol is Diode:SMF12A and the footprint Diode_SMD:D_SMF, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SMF12A?
SOD-123, with 2 pins. Its footprint is drawn on this page.
Where is the SMF12A datasheet?
FMS publishes it: the Datasheet link on this page opens it.
Where can I order the SMF12A?
JLCPCB lists it as part C163748, with 0 in stock; the sellers' links on this page open their listings.
What can replace the SMF12A?
Parts like it in the library: the SMF12A by hongjiacheng, the SMF12A by MDD, the SMF12A by Shandong Jingdao Microelectronics and the SMF12A by GOODWORK. Check their datasheets: a part that fits the footprint may still differ in its ratings.
