Is there a KiCad symbol and footprint for the FHD9540C?
Yes. The symbol is Pinmap_Generic:Q_NMOS_1G_2D_3S and the footprint Package_TO_SOT_SMD:TO-252-2, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the FHD9540C?
TO-252-2, with 3 pins. Its footprint is drawn on this page.
Where is the FHD9540C datasheet?
FeiHong publishes it: the Datasheet link on this page opens it.
Where can I order the FHD9540C?
JLCPCB lists it as part C438787, with 0 in stock; the sellers' links on this page open their listings.
What can replace the FHD9540C?
