FGH50N6S2D, FSC (Fairchild Semi-Conductor) TO-247

FGH60N6S2, FSC, TO-247

HGT1N40N60A4D, FSC IGBT, try to get samples as they go quickly.  FWIW - If you have to actually purchase these, God forbid, small quantities (less than 50 pieces) sell for around $49.95 each, providing you can locate a distributor that actually has them in stock, and realizing that they may not be on this continent, in which case you get to be introduced into the world of International Money Transfer Fees and shipping charges, counterfeit parts from China and just possibly, Ebola.  Just kidding on the last point, but, you never know.........

Heatsink Info & Sources

Aavid-Thermalloy and R-Theta, http://www.r-theta.com, have a very nice selection of online whitepapers, guides, references, and programs.  R-Theta, last I was there, had a very nice online finite element applet to test your "thermal solutions."  The extrusions I got from R-Theta were not machined but did have a surface flat enough for Steve Ward to mount two IGBT bricks to with no further prep work.

In many cases, one can just find thick scrap plate aluminum and tap some holes in it.  All the fancy fins and such help, but just being bolted to a big chunk of Al does 80% of the job.  It "needs" a "flat" surface, otherwise when you bolt the device down it might make a cracking noise :-(   Also, the holes for mounting need to be well de-burred so there are not edges that might hold the gap open.  Ideally, if the device to sink gap is about 0.0005 inch, you are home free.  If it is 0.005 inch, your are dead no matter what...  Big copper plate IGBT's are more forgiving.  Blow air onto it for about a 10X increase in thermal dissipation...  Water cool for 50X.

depending on what type of package (assuming IGBT, FET, etc.).  I have found that the Pentium IV heatsinks work great for two SOT-227's, but don't use the wimpy DC fan that comes with them.
