What is a bipolar junction transistor?
Q: What is a bipolar junction transistor?
A: 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.
Q: What are the different uses of BJTs?
A: BJTs can be used as amplifiers, switches, or in oscillators.
Q: Where can BJTs be found?
A: BJTs can be found either on their own, or in large numbers as parts of integrated circuits.
Q: Why are they called bipolar transistors?
A: BJTs are named bipolar transistors because their operation involves both electrons and holes.
Q: What is hfe in BJTs?
A: The current gained is measured in hfe, Forward Current Gain.
Q: What is the typical range of hfe in BJTs?
A: The typical amount of hfe in BJTs can be between 200-350.
Q: What is the function of Forward Current Gain in a BJT?
A: The Forward Current Gain (hfe) in a BJT determines the amplification effect of the transistor.
