And, I think that’s because in a BJT, the saturation is sometimes referred to as the linear region. People forget that BJTs and MOSFETs (despite having similar looking characteristics) have a different saturation mechanism. – Andy aka 2 hours ago That is really annoying..

NettetThe fusion of these two diodes produces a three layer, two junction, three terminal device forming the basis of a Bipolar Junction Transistor, or BJT for short. Transistors are three terminal active devices made from different semiconductor materials that can act as either an insulator or a conductor by the application of a small signal voltage. NettetActive region This is the region in which transistors have many applications. This is also called as linear region. A transistor while in this region, acts better as an Amplifier. This region lies between saturation and cutoff.
