Do not confuse this with a MOSFET in saturation, which behaves similarly to the BJT in the active region. Figure 5: Active Region, B-E Diode is Forward Biased and B-C Diode is Reverse Biased (iii) Cuto Region 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 chuck schumer\u0027s net worth 2020WebMay 22, 2024 · This is known as the saturation region. The break-over point is fairly small at just a few tenths of a volt. This can be found on a data sheet as \(V_{CE(sat)}\). The saturation region is used in transistor switching applications. At the extreme right is another region where the collector current rises rapidly. This is called the breakdown region. chuck schumer twitter capitol
