Yep, did that in one case. But this rapidly approaches economic limits where even considering the labor for mounting, the lone TO220 wins. Asian production assumed.

That device has lots of capacitance. Are you switching at high frequency?

Do you mean gate-source? One gate driver chip per MOSFET (I am using two) seems to handle it just fine. This part is supposed to switch much faster than IRFS3206 (on paper, at least ;o) ) I made TO220 package out of the part (soldered it to the TO220 tab). Haven't figured out if it's better as the part seems to be misbehaving.
