A transistor has a power rating of 8 W for a case temperature of 25Â°C. If derating factor is 30 mW/Â°C, the power rating for 55Â°C, case temperature is

Electronics and Communication Engineering (ECE) : Analog Electronics - Quiz(MCQ)

8 W

7.5 W

7.1 W

6.8 W

Correct Answer : Option (C) : 7.1 W

Explanation :

Power rating = 8 - (55 - 25)(30 x 10^-3) = 7.1 W.
