Is there a KiCad symbol and footprint for the SWN4N65D?
Yes. The symbol is Pinmap_Generic:Q_NMOS_1G_2D_3S and the footprint EasyEDA_Cloud:TO-251_L6.6-W2.4-P2.30-L, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SWN4N65D?
TO-251N, with 3 pins. Its footprint is drawn on this page.
Where is the SWN4N65D datasheet?
Samwin publishes it: the Datasheet link on this page opens it.
Where can I order the SWN4N65D?
JLCPCB lists it as part C5151803, with 0 in stock; the sellers' links on this page open their listings.
What can replace the SWN4N65D?
Parts like it in the library: the MOT8N65C by MOT, the WGU5N65SE by Wild Goose, the NCE65T540I by Wuxi NCE Power Semiconductor and the NCE70T900I by Wuxi NCE Power Semiconductor. Check their datasheets: a part that fits the footprint may still differ in its ratings.
