Is there a KiCad symbol and footprint for the SMF51A?
Yes. The symbol is Diode:SMF51A 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 SMF51A?
SOD-123, with 2 pins. Its footprint is drawn on this page.
Where is the SMF51A datasheet?
FMS publishes it: the Datasheet link on this page opens it.
Where can I order the SMF51A?
JLCPCB lists it as part C266701, with 0 in stock; the sellers' links on this page open their listings.
What can replace the SMF51A?
Parts like it in the library: the SMF51A by PTTC, the SMF51A by AnBon, the SMF51A by DOWO and the SMF51A by Jiangsu Changjing Electronics Technology (CJ). Check their datasheets: a part that fits the footprint may still differ in its ratings.
