I have a bank of 4 of these:
http://www.irf.com/product-info/datasheets/data/irfp3206pbf.pdf
Bolted onto a plate of 4" x 6" x 3/8 "aluminum, with a 120mm,12V Fan cooling.
The load thru them takes them to about 85C (case temp), a 50C delta. Peak 800A pulse currents (shared by 4 FETS) at < 50uS, 2.5% DC.
I was just wondering how to calc. the max safe operating 'case' temp for these units given these conditions.
thanks...
