i have ran acros some parts when i google there model that come back as being power mosfets or mosfets. what is a mosfet though? i'm guessing htat a power mosfet is just a hevy duty mosfet for doing somthing with power. from what i have heared they sound identical to a transistor in what they do but then why call the msomthing else so i think i misunderstood it or the source was wrong.
