H.W2 Sow at to an 9 • A Power transistor for which TJmax = 180°c Can dissipate a case temperature of so°c. If it is connected heat sink using insulating washer for which the thermal resistance is 0.6 °C /w, what heat sink temp. necessary to ensure safe operation at 30w ? For an ambient temp. at 39°℃, what heat sink thermal resistance is required? If a praticular aluminum finned heat sink, thermal resistance in still air is 4.5°C /w per centimeter of length, how long a heat Sink is needed?
