Is there a KiCad symbol and footprint for the SMF48A?
Yes. The symbol is Diode:SMF48A 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 SMF48A?
SOD-123FL, with 2 pins. Its footprint is drawn on this page.
Where is the SMF48A datasheet?
Jiangsu Changjing Electronics Technology (CJ) publishes it: the Datasheet link on this page opens it.
Where can I order the SMF48A?
JLCPCB lists it as part C1509577, with 2,939 in stock; the sellers' links on this page open their listings.
What can replace the SMF48A?
Parts like it in the library: the SMF48A by hongjiacheng, the SMF48A by JSMSEMI, the SMF48A by FOSAN and the SMF48A-MS by MSKSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
