If the zero signal dissipation of a transistor is 1W, then power rating of the transistor should be at least___________________?
Correct answer: D. 1 W
- A. 5 W
- B. 33 W
- C. 75 W
- D. 1 W
Explanation
The transistor's power rating must be at least equal to its maximum expected dissipation; with a zero-signal dissipation of 1 W, the minimum rating is 1 W. Practical designs may choose a higher rating for a safety margin.
