Bipolar junction transistor
transistor that uses both electrons and holes as charge carriers
(Redirected from Hfe)
A bipolar junction transistor (BJT or bipolar transistor) is a type of transistor that relies on the contact of two types of semiconductor in order for it to work. BJTs can be used as amplifiers, switches, or in oscillators. BJTs can be found either on their own, or in large numbers as parts of integrated circuits.[1]
They are named bipolar transistors because their operation involves both electrons and holes.
The current gained is measured in hfe, Forward Current Gain. Typical amount can be between 200-350.
