Is there a KiCad symbol and footprint for the FDN340P?
Yes. The symbol is Transistor_FET:FDN340P and the footprint Package_TO_SOT_SMD:SOT-23, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the FDN340P?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the FDN340P datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the FDN340P?
JLCPCB lists it as part C75469, with 19,706 in stock; the sellers' links on this page open their listings.
What can replace the FDN340P?
Parts like it in the library: the AO3400 by GOODWORK, the AP2300 by ALLPOWER, the AO3400A by Alpha & Omega Semiconductor and the AO3400A by UMW. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the FDN340P?
111 boards in 96 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
