In reverse blocking mode of a thyristor______?

Correct answer: C. junction J1, J3 is in reverse bias and J2 is in forward bias.

  • A. junction J2 is in reverse bias and J1, J3 is in forward bias.
  • B. junction J3 is in forward bias and J1, J2 in reverse bias.
  • C. junction J1, J3 is in reverse bias and J2 is in forward bias.
  • D. junction J1 and J2 is in forward bias and J3 is in reverse bias.

Explanation

With reverse voltage applied, J1 and J3 are reverse biased and J2 is forward biased. The two reverse-biased outer junctions block reverse current through the thyristor.
