Questions
Is there a KiCad symbol and footprint for the FDS4559?
Yes. The symbol is Transistor_FET:FDS4559 and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the FDS4559?
SO-8, with 8 pins. Its footprint is drawn on this page.
Where is the FDS4559 datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the FDS4559?
JLCPCB lists it as part C97044, with 367 in stock; the sellers' links on this page open their listings.
What can replace the FDS4559?
Parts like it in the library: the SGO100N08L by Shanghai Super Semiconductor, the AP10H10S by A Power microelectronics, the IRF7478TRPBF by Infineon Technologies and the IRF7488TRPBF by Infineon Technologies. Check their datasheets: a part that fits the footprint may still differ in its ratings.
