The Power Transistor: A Module on Heat Transfer. Tech Physics Series.
Technical Education Research Center, Cambridge, MA.
This module is intended to provide an understanding of the principles related to heat transfer. The objectives are designed to enable the learner to select and install a device for measuring the temperature of a power transistor, determine power ratings, measure the transient response for a power level and its final equilibrium temperature. Other objectives include being able to find thermal resistance and the time constant of the system; use thermal resistance, final temperature, and time constant to find heat capacity; find final temperature for any power input and an operating point; find the factors affecting thermal resistance; and lower the thermal resistance to improve dissipation of power.
