Is there a KiCad symbol and footprint for the SMF3.3A?
Yes. The symbol is Device:D_TVS and the footprint Diode_SMD:D_SOD-123, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SMF3.3A?
SOD-123, with 2 pins. Its footprint is drawn on this page.
Where is the SMF3.3A datasheet?
FMS publishes it: the Datasheet link on this page opens it.
Where can I order the SMF3.3A?
JLCPCB lists it as part C717050, with 0 in stock; the sellers' links on this page open their listings.
What can replace the SMF3.3A?
Parts like it in the library: the SMP3V3-M3/85A by Vishay Intertechnology, the UCLAMP3381P.TFT by SEMTECH, the SP3384NUTG by Littelfuse and the VTVS3V3GSMF-HM3-08 by Vishay Intertechnology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
