    Hi, I haven't used MOSFETs much before. Is the top (the plate with hole, labelled as thermal pad in the datasheet) connected to the drain? And if so could I connect to the drain using this instead of the drain pin? (have to squeeze it into a small space where this would be helpful, and am curious if this is an option..)

    the tab is sometimes connected to the drain. some mosfets have isolated tabs, you just have to check the data sheet for that particular mosfet. you could check for a connection beween the leads of he mosfet and the tab for a connection.
