Heat sink sources
 

the heat sinks in my Digikey, Mouser, etc. catalogs aren't of sufficient C/W
capacity (2 - 5 C/W). Can anyone suggest one or more sources which will
sell for TO-220 style devices in small quantities?

Are you willing to drill holes?

These are available from Digikey.

I made my own some time ago for two TO220 devices from a piece of Al
channel. It was much easier to mount on my PCB than any of the commercial
ones and had plenty of dissipation for my application.
