What is the highest junction temperature you would expect

Reference no: EM131018962

A power transistor operating at an ambient temperature of 50°C, and an average emitter current of 3 A, dissipates 20 W. If the thermal resistance of the transistor is known to be less than 3°C/W, what is the highest junction temperature you would expect? If the transistor VBE measured using a pulsed emitter current of 3 A at a junction temperature of 25°C is 0.80 V, what average VBE would you expect under normal operating conditions? (Use a temperature coefficient of -2 mV/°C.)
