Hello All,
It's for first time now when I need to mount power IRF840 transistor on heat sink. I am not absolutely sure how to do it and have a couple of questions:
1. I was once advised that a heat sink with dimensions 300 x 100 x 26 mm (as shown on picture attached) would be good enough. Whether it's really good enough, in your opinion?
2. I am not sure how to mount IRF840 on a heat sink. IRF840 is produced in TO220AB package (also shown on a picture attached) and its drain contacts heat sink thermally and electrically as well (IRF840 is tighten to heat sink by bolt). So I will need to isolate whole heat sink from all other parts (case, for example) - is my understanding correct?
Thank you.
