Is there a KiCad symbol and footprint for the SMF24AT?
Yes. The symbol is Diode:SMF24A 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 SMF24AT?
SOD-123, with 2 pins. Its footprint is drawn on this page.
Where is the SMF24AT datasheet?
FMS publishes it: the Datasheet link on this page opens it.
Where can I order the SMF24AT?
JLCPCB lists it as part C341550, with 0 in stock; the sellers' links on this page open their listings.
What can replace the SMF24AT?
Parts like it in the library: the SMF24A by hongjiacheng, the SMF24A by Shandong Jingdao Microelectronics, the SMF24A by Jiangsu Changjing Electronics Technology (CJ) and the SMF24A by JSMSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
