![]() ![]() A diode has a forward voltage that it “grabs” from the available voltage. ![]() Since most of us don’t have a 0.7V battery, how do we turn on the transistor?Įasy! The base-to-emitter part of a transistor works like a diode. If you had a 0.7V battery, you could have connected it between the base and emitter, and the transistor would have turned ON. To turn the transistor ON, you need a voltage of about 0.7V between the base and the emitter. ![]()
