Bjt saturation region characteristics

WebThen bipolar transistors have the ability to operate within three different regions: Active Region – the transistor operates as an amplifier and Ic = β*Ib; Saturation – the transistor is “Fully-ON” operating as a switch and Ic = I(saturation) Cut-off – the transistor is “Fully-OFF” operating as a switch and Ic = 0 WebApr 9, 2024 · The output characteristics of BJT can be divided into three areas – cut-off, saturation and active region. In the cut-off region both collector-base and emitter-base pn-junctions are reverse-biased – transistor is off. In the active region , base-collector pn-junction is reverse-biased, and base-emitter – forward-biased.
