The forward break over voltage is the

(a) anode-cathode voltage at which conduction starts with gate signal applied

(b) anode-cathode voltage at which conduction starts with no gate signal applied

(c) gate voltage at which conduction starts with no anode-cathode voltage

(d) gate voltage at which conduction starts with anode-cathode voltage applied

The question was posed to me during a job interview.

I'd like to ask this question from Thyristors-2 in chapter Power Electronics Devices of Power Electronics

Correct option is (b) anode-cathode voltage at which conduction starts with no gate signal applied

Easy explanation: It is the forward voltage at which the middle junction breaks down without any gate signal and pushes the device into the conducting state.
