Question

The collector characteristics for a certain transistor are shown in Figure P9.9. a. Find the ratio $I_C / I_A$ for $V_{C E}=10 \mathrm{~V}$ and $I_A=100$ $\mu \mathrm{A}, 200 \mu \mathrm{~A}$, and $600 \mu \mathrm{~A}$. b. The maximum allowable collector power dissipation is 0.5 W for $I_{\mathrm{n}}=500 \mu \mathrm{~A}$. Find $V_{C E}$.

Step 1

The collector characteristics of a transistor show the relationship between collector current (IC) and collector-emitter voltage (VCE) for different values of base current (IB) or, in this case, input current (IA). Step 2: For part (a), we need to find the ratio Show more…
