Reconsider Prob. 1640. Using an appropriate software, plot the amount of power the transistor can dissipate safely

Question:

Reconsider Prob. 16€“40. Using an appropriate software, plot the amount of power the transistor can dissipate safely as a function of the maximum case temperature in the range of 60°C to 90°C. Discuss the results.


Reconsider Prob.

A transistor with a height of 0.4 cm and a diameter of 0.6 cm is mounted on a circuit board. The transistor is cooled by air flowing over it with an average heat transfer coefficient of 30 W/m2·K. If the air temperature is 55°C and the transistor case temperature is not to exceed 70°C, determine the amount of power this transistor can dissipate safely. Disregard any heat transfer from the transistor base.

Air 55°C Power transistor 0.6 cm Tss 70°C 0.4 cm -0.4 cm-
