variable power supply circuit
xavier60:
Start with about 1°C/W for the TO-247's thermal pad.
EDIT: Or is it a TO-220 part? which will be much worse.
aneesh:
it is t0 220 with large heatsink . plz refe the above circuit
xavier60:
One way to calculate the power dissipated by the MOSFET, measure the voltage between Drain and Source, then multiply it by the current.
aneesh:
drop is something nearly 15v and 0.5A

15 x 0.5 = 7.5W
What information do you have about the heatsink?
