BJT Basics
This is the number of PN junctions in a BJT.
What is two?
What is IC / IB?
The mode of operation when the transistor behaves like a wire or a closed switch.
What is saturation?
This current is called the control current of a BJT.
What is IB or base?
This is the ratio of IC over IB.
What is Beta DC
This is BetaDC if IB = 1mA and a IC = 120mA
What is 120?
The mode of operation where the transistor acts like a broken wire or an open switch.
What is cutoff?
This will be the approximate base current when a transistor is in cutoff.
What is 0A?
The emitter-base junction of an NPN transistor must be biased this way to conduct.
What is forward bias?
This is BetaDC if IB = 10uA and a IC = 5mA
What is 500
The mode of operation where increasing current to the base increases current through the collector.
What is the linear/active region?
A multimeter will read this on a properly functioning silicon NPN BJT when using diode test mode between the base and the emitter.
What is 0.7V?
This value is equal to IE - IB.
What is IC?
This is IC if IB = 10uA and BetaDC = 400
What is 4mA?
The mode of operation where VCE = 0
What is saturation?
This type of transistor is most commonly used in computers & digital logic
What are MOSFETS?
This is what the Base voltage must be, with respect to the emitter, for normal operation of a BJT.
What is Positive?
This is IB if BetaDC = 360 and IC = 36mA
What is 100uA?
The mode of operation where VC = Voltage Supply
What is cutoff?
This is section of a BJT is thin and lightly doped.
What is the base?
