Which of the following statements is true for the Cutoff mode of BJT operation modes?

Option: 1

 In the cutoff mode, both the junctions of the transistor are reverse biased.


Option: 2

 In the cutoff mode, both the junctions of the transistor are forward biased.


Option: 3

In the active mode, one junction (emitter to base) is forward biased and another junction (collector to base) is reverse biased


Option: 4

In the active mode, one junction (emitter to base) is reverse biased and another junction (collector to base) is forward  biased

  • BJT operation modes-

1.Cutoff mode- In the cutoff mode, both the junctions of the transistor are reverse biased.

As in reverse bias condition, no current flows through the device. Hence, no current flows through the transistor. Therefore, the transistor is in off state and acts as an open switch. The cutoff mode of the transistor is used in switching operation for switch OFF application.

 So correct option is option A
