Is there a KiCad symbol and footprint for the FDD306P?
Yes. The symbol is Pinmap_Generic:Q_PMOS_1G_2D_3S and the footprint EasyEDA_Cloud:TO-252-2_L6.6-W6.1-P4.57-LS9.9-BR-CW, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the FDD306P?
TO-252, with 3 pins. Its footprint is drawn on this page.
Where is the FDD306P datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the FDD306P?
JLCPCB lists it as part C336030, with 0 in stock; the sellers' links on this page open their listings.
What can replace the FDD306P?
Parts like it in the library: the 30N06 by UMW, the 50N06 by HL, the 100N03A by UMW and the 15N10 by UMW. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the FDD306P?
4 boards in 2 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
