Question

The characteristic curve for a diode is shown in the figure for forward bias mode. The cut-off voltage for this diode is approximately.

(a) 0.5 V

(b) 0.8 V

(c) 1 V

(d) > 1 V

Answer 1

The correct option is (a) 0.5 V.

Explanation:

 Cut-off voltage is the voltage applied across diode in forward bias mode to overcome the potential barrier region. Upto this, forward bias voltage current through diode is approximately zero.
