Question: A silicon power transistor is operated with a heat sink ( SA = 1.5ºC/W). The transistor, rated at 150 W (25ºC), has JC = 0.5º C/W, and the mounting insulation has CS = 0.6 ºC/W. What is the maximum power that can be dissipated if the ambient temperature is 50ºC and T Jmax = 200 ºC?
Options
A : 61.5 W
B : 60.0 W
C : 57.7 W
D : 55.5 W
