Is there a KiCad symbol and footprint for the SP40N03BTH?
Yes. The symbol is EasyEDA_Cloud:GL50N03A4 and the footprint EasyEDA_Cloud:TO-252-3_L6.6-W6.1-P4.58-LS10.1-BR, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SP40N03BTH?
TO-252, with 3 pins. Its footprint is drawn on this page.
Where is the SP40N03BTH datasheet?
Siliup publishes it: the Datasheet link on this page opens it.
Where can I order the SP40N03BTH?
JLCPCB lists it as part C41354887, with 1,560 in stock; the sellers' links on this page open their listings.
What can replace the SP40N03BTH?
Parts like it in the library: the HY3404D by HUAYI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
