Discuss the below in detail:
Q: A pnp power transistor operates with an emitter-to-collector voltage of 5 V, an emitter current of 5 A, and VEB = 0.8 V. For β=20, what base current is required? What is IS for this transistor? Compare the emitter-base junction area of this transistor with that of a small-signal transistor that conducts iC = 1 mA with vEB 0.70 V. How much larger is it?
