A BJT is a current-controlled device in which current flows due to both majority and minority charge carriers.
A BJT works mainly in two regions, i.e. active (amplification) and cut-off (open switch).
In the active region, \(I_E=I_C+I_B\)
Here, the collector current is due to both majority and minority charge carriers and it flows from collector to emitter.
In the cut-off region, IB = 0, and then a very small leakage current flows from the collector to the emitter ( ICEO). This current is only due to minority charge carriers.
∴ The collector current in cut-off is:
IC = ICEO
where ICEO = Minority current flowing from collector to emitter with the base open-circuited
