Is there a KiCad symbol and footprint for the SMF20A?
Yes. The symbol is Diode:SMF20A 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 SMF20A?
SOD-123, with 2 pins. Its footprint is drawn on this page.
Where is the SMF20A datasheet?
FMS publishes it: the Datasheet link on this page opens it.
Where can I order the SMF20A?
JLCPCB lists it as part C266689, with 0 in stock; the sellers' links on this page open their listings.
What can replace the SMF20A?
Parts like it in the library: the SMF20A by hongjiacheng, the SMF20A by MDD, the SMF20A by Shandong Jingdao Microelectronics and the SMF20A by Jiangsu Changjing Electronics Technology (CJ). Check their datasheets: a part that fits the footprint may still differ in its ratings.
