How do you tell, by looking at the data sheet, which, if any, of the G,D,S is connected to the package's conductive head sink?

Using my multimeter, I can see that the drain is connected to the heat sink. But I don't see this info on the data sheet.

Re: MOSFET heat sink connection
I think it's pretty uncommon for it to be connected to anything but the drain.
[ I actually think it's pretty much a MOSFET "by definition" kind of thing that it's connected to the drain, but if I say that, a counterexample will certainly appear. ]

Re: MOSFET heat sink connection
I always take an ohm meter and check the resistance between the leads and the back to check for continuity to determine if any pin is common with the back/sink portion of the device. Depending on the device type you would then chose to insulate it from the chassis or ground it.
