Operating regions of a BJT

A Bipolar Junction Transistor (BJT) is a three-layer semiconductor device that consists of two pn junctions. The operation of a BJT can be classified into three regions: the cutoff region, the active region, and the saturation region.

Cutoff region

In the cutoff region, both the collector-base (CB) junction and the base-emitter (BE) junction are reverse-biased. In this region, the transistor is effectively turned off, and no current flows between the collector and the emitter. The cutoff region is characterized by a very low collector current (IC) and a high collector-emitter voltage (VCE).

Active region

In the active region, the CB junction is reverse-biased, while the BE junction is forward-biased. In this region, the BJT operates as an amplifier. The base current (IB) controls the collector current (IC), allowing the BJT to amplify the input signal. The active region is characterized by a moderate IC and VCE.

Saturation region

In the saturation region, both the CB and BE junctions are forward-biased. In this region, the BJT acts as a closed switch, allowing a large current to flow between the collector and the emitter. The saturation region is characterized by a high IC and a low VCE.

Answer

In the given scenario, where both the CB and BE junctions are forward-biased, the BJT is operating in the saturation region. This is because the forward biasing of both junctions allows a large current to flow between the collector and the emitter, resulting in saturation. In this region, the BJT acts as a closed switch and is fully conducting.

Therefore, the correct answer is option 'A' - saturation region.
