Is there a KiCad symbol and footprint for the SWF4N70D?
Yes. The symbol is Pinmap_Generic:Q_NMOS_1G_2D_3S and the footprint EasyEDA_Cloud:TO-220F-3_L10.2-W4.7-P2.54-L, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SWF4N70D?
TO-220F, with 3 pins. Its footprint is drawn on this page.
Where is the SWF4N70D datasheet?
Samwin publishes it: the Datasheet link on this page opens it.
Where can I order the SWF4N70D?
JLCPCB lists it as part C5151770, with 0 in stock; the sellers' links on this page open their listings.
What can replace the SWF4N70D?
Parts like it in the library: the JCS15N70FC by Jilin Sino-Microelectronics, the TSF10N80M by Truesemi, the WML25N80M3 by Wayon and the STP10NK70ZFP-JSM by JSMSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
