In cut off mode(a) The base-emitter junction is forward biased and emitter-collector junction is reversed biased(b) The base-emitter junction is forward biased and emitter-collector junction is forward biased(c) The base-emitter junction is reversed biased and emitter-collector junction is reversed biased(d) The base-emitter junction is reversed biased and emitter-collector junction is forward biasedThe question was posed to me during an interview for a job.I need to ask this question from BJTs Device Strucutres and Physical Operations topic in section Bipolar Junction Triodes (BJTs) of Electronic Devices & Circuits

Answer»

The CORRECT CHOICE is (c) The base-emitter junction is reversed BIASED and emitter-collector junction is reversed biased

Explanation: In cut-off mode there is no current flowing through the BJT hence both junctions must be reversed biased else if either of them is forward biased then the current will flow.
