Mosfets are costly. Have you tried the local markets?

Information sharing improves knowledge of both.



If you want cheap, go to electronics waste and search faulty motherboards. I have seen that MoBo technicians are searching MoBo lots (Garbage) for their items.
However, I will search not only of your item but need to explore SMD Market in Kolkata.

May be delay to you.

yeah, those are DPAK, same as I have.. I see there is only one damaged mosfet..
yes, you sure can try as kalyanprodhan says.. rummaging helps a lot.. but i'm not sure if you'll get a 120A transistor..
