Hi, i want to design a heat sink for following mosfet(adsbygoogle = window.adsbygoogle || []).push({});

http://au.element14.com/vishay-formerly-i-r/irfp360pbf/mosfet-n-400v-23a-to-247ac/dp/8649359

its technical data sheet is provided here

http://www.irf.com/product-info/datasheets/data/irfp360.pdf

i am not sure how to design it...by design i mean just the mathematical value for C/W not schematic.

i read somewhere that the formula for finding the value for heat sink is (Tmax - Tamb)/Pd

the ambient temperature is 40C

from my calculation i found the heat sink value to be (150-40)/(280) = 0.4 C/W...is this correct...i located the value for Tmax and Pd (power dessipated) from the datasheet. Is this correct? please any help is appreciated.
