Is there a KiCad symbol and footprint for the STW45NM50?
Yes. The symbol is Pinmap_Generic:Q_NMOS_1G_2D_3S and the footprint EasyEDA_Cloud:TO-247-3_L15.8-W5.0-P5.44-L-1, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the STW45NM50?
TO-247, with 3 pins. Its footprint is drawn on this page.
Where is the STW45NM50 datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the STW45NM50?
JLCPCB lists it as part C2688515, with 8 in stock; the sellers' links on this page open their listings.
What can replace the STW45NM50?
Parts like it in the library: the IPW65R110CFDFKSA2 by Infineon Technologies. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the STW45NM50?
3 boards in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
