Questions
Is there a KiCad symbol and footprint for the IRF9543?
Yes. The symbol is Pinmap_Generic:Q_PMOS_1G_2D_3S and the footprint Package_TO_SOT_THT:TO-220-3_Vertical, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the IRF9543?
TO-220-3, with 3 pins. Its footprint is drawn on this page.
Where is the IRF9543 datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the IRF9543?
JLCPCB lists it as part C3280580, with 0 in stock; the sellers' links on this page open their listings.
What can replace the IRF9543?
Parts like it in the library: the IRF540NPBF by Infineon Technologies, the IRF9540NPBF by Infineon Technologies, the IRF3205PBF by Infineon Technologies and the IRF740PBF by Vishay Intertechnology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
