A TO-220 package has the metal "heatsink" with a hole in it. The metal tab is connected electrically to the drain of a MOSFET I want to use. I want to use 3 of them actually and was simply going to screw them to an aluminum or steel enclosure for cooling but If they are electrically connected, is that possible? The tab can also be soldered to a large ground pane type area as well right?? As long as the individual MOSFETS have their own isolated pads??? Ive also seen individual heat sinks you can attach to the tabs but what good would that do inside an enclosure??? Stupid questions I know....
