Q1:

A transistor has a maximum power dissipation of 350 mW at an ambient temperature of 25°C. If derating factor is 2 mW/°C, the maximum power dissipation for 40°C ambient temperature is

A 300 mW

B 330 mW

C 350 mW

D 380 mW

ANS:C - 350 mW

Derating improves reliability but does not affect maximum power dissipation.
