/diy/ - Do It Yourself

Any reason you are using TO220s instead of the much bigger available packages, like SOT-227?

Also as an aside I find it mildly annoying that datasheets list these absurdly high current limits, as if the source pin on a TO220 would be able to carry 195A no big deal.
It turns out the test methods they use involve exotic cooling which lets them use such high numbers for the absolute maximum limits. Look at http://www.irf.com/technical-info/appnotes/an-1140.pdf to see what I mean.
