Q16
A transistor is used as a switch. Assuming that the total power loss in the transistor (Collector and Base losses) is equal to 108.5 W. If the ambient temperature is 25°C, and the thermal resistors are given as: Ryc = 0.4°C/W. Rcs = 0.1 °C/W, RSA = 0.5°C/W, then the junction temperature T, would be equal to: Tc T, w Ric Ts Rcs Rea TA Select one a 555°C b. 111.5°C 88.5 C d. 133.5 °C
