12.54 The emitter follower in Fig. 12.3 drives a load resistance RL = 50 Ω with an output ranging between vO = ±5 V. It operates with VCC = 10 V and I = 200 mA. What is the peak power dissipation in Q1 and what is the corresponding output voltage vO? What is the peak power dissipation in Q2 and what is the corresponding vO? If identical transistors are to be used for Q1 and Q2, what minimum specifications are required for ICmax and BVCEO allowing a factor-of-2 safety margin?
2 W; +5 V; 3 W; +5 V; 600 mA; 30 V
