The emitter-base and collector-base junctions are forward biased in this region. Switching and digital logic circuits are primarily used in the Cutoff Region. In this mode, the BJT is switched off and the circuit is an open circuit. There is no current flow except small leakage currents because both PN Junctions are reverse biased (usually in the order of a few nanoamps or pico amps). The collector-base junction and the emitter-base junction are reverse biased in this mode.

Current flows between the emitter and the collector in this mode, with the amount of current flow proportional to the base current. Two junctions are biased differently in active mode, with the emitter-base junction being forward biased and the collector-base junction being reverse biased. *This information is for general informational purposes only, we will not be liable for any loss or damage caused by the above information.The transistor is generally used as a current amplifier in this mode.
