Stan is right, they do come off, you just have to use a high enough wattage soldering iron to be able to melt the solder on the tab and the heatsink. My 70W Hakko has taken them off identical looking boards. It helps a bunch to use a little solder on the iron to give better heat transfer to the board.

FWIW, you can also select a TO-220 triac with similar specifications and solder it to what's left, it's tab is longer and may cover the area you ripped up.
