Determine the maximum dissipation that should be allowed for a 75W silicon transistor rated at 22°C. Derating is required above 22°C by a derating factor of .35 W/°C at a case temp of 142°C. I'm stumped. Not sure where to even start. I'm going to take a smoke break before I throw my computer out of the window. I've been taking a test for 3 hrs.
