What is the collector current when the BJT is working in reverse active mode?
A transistor in reverse active mode conducts, even amplifies, but current flows in the opposite direction, from emitter to collector. To put a transistor in reverse active mode, the emitter voltage must be greater than the base, which must be greater than the collector (VBE<0 and VBC>0).
What is the reverse saturation current in diode?
The reverse saturation current is the part of the reverse current in a semiconductor diode which is caused by the diffusion of minority carriers from the neutral regions to the depletion region.
What is the reverse saturation current in a BJT?
Reverse saturation current in a BJT: active and reverse active modes. Since it depends on the area of the junction () and – as the primary source itself explained – the area of the BC junction (in forward bias for reverse active mode) is much greater than the area of the BE junction (in forward bias for active mode),…
What are the different modes of BJT operation?
Modes of Operation of BJT (Active Mode, Cutoff Mode, Saturation Mode, Reverse Active Mode of Transistor)/Bipolar Junction Transistor Here we will learn the basic concepts of Bipolar Junction Transistor (BJT) and how to operate BJT transistor in different operating modes.
How is saturation mode different from active mode?
The transistor in saturation mode is also said to be in ‘1 state’ or ‘ON state’ Then the transistor is under reverse saturation region. The reverse active mode is just opposite to the active mode because in this mode of operation the emitter-base junction is reverse biased while the collector-base junction is forward biased.
What happens in saturation mode of a transistor?
In saturation mode of the transistor, both the junctions (emitter-base junction and collector-base Junction) are forward biased. You can also observe this biasing in this image.
