A transistor has a maximum power dissipation limit of 300 mW for ambient temperature up to 25 °C. If the maximum allowable junction temperature is 175 °C, then what is the limit of the device is an ambient temperature of 55 °C ?
Added by Amanda A.
Step 1
The maximum junction temperature is 175 °C and the rated ambient temperature is 25 °C, so the temperature difference is 175 °C - 25 °C = 150 °C. Show more…

The case of a power transistor, which is of length L = 10 mm and diameter D = 12 mm, is cooled by an air stream of temperature T∞ = 25°C. Transistor (Ts, Pelec). Air T∞, h. Under conditions for which the air maintains an average convection coefficient of h = 100 W/m² · K on the surface of the case, what is the maximum allowable power dissipation if the surface temperature is not to exceed 85°C?

The transistor in the common-emitter circuit in Figure $15.15$ has parameters $P_{T}=2.5 \mathrm{~W}, V_{C \text { ,sus }}=25 \mathrm{~V}$, and $I_{C \max }=500 \mathrm{~mA}$. Let $R_{L}=100 \Omega$. What is the value of $V_{c c}$ such that the maximum power is delivered to the load?
A power MOSFET is used in the inverter circuit shown in Figure $15.26$ in which $V_{D D}=200 \mathrm{~V}$ and $R_{D}=100 \Omega$. The on resistance of the transistor is $R_{\mathrm{cn}}=2 \Omega$ at a junction temperature of $25^{\circ} \mathrm{C}$. The on resistance increases linearly with temperature and is $3 \Omega$ at a junction temperature of $100^{\circ} \mathrm{C}$. Plot the power dissipated in the transistor as a function of junction temperature.
