Looking for low-profile, but effective TO-220 heatink

luvdunhill · 27th February 2008, 07:45 PM

I have seen in several pictures a TO-220 heatsink that is about as tall as the package, but has fins that go behind the device. It looks like a hole must be tapped into the heatsink to attach the device.

Here's one such example:

I'm assuming these are non-US parts, perhaps Fischer, or I just haven't seen them around much.

Bottom line, is I need something about the height of the device itself, and these might just work perfect if I can find them

There's a standard series of Aavid/Thermalloy parts that look like that. Digi-key has them,
