What Is the Cutoff Region?

Cutoff region

This is the region in which transistor tends to behave as an open switch. The transistor has the effect of its collector and base being opened. The collector, emitter and base currents are all zero in this mode of operation.

What is cutoff region in FET?

The Cutoff Region of a FET transistor is the region where the drain-source channel resistance is at its maximum and there is no no drain current, ID, flowing from the drain to the source of the FET transistor. In this region, the transistor is off.

What is active region and cutoff region?

The region between cut off and saturation is known as active region. In the active region, collector-base junction remains reverse biased while base-emitter junction remains forward biased. Consequently, the transistor will function normally in this region. Note.
