Question

The cut-in voltage for silicon diode is approximately _____.

Answer 1

Cut-in voltage:

1. The voltage at which the forward diode current begins to start increasing rapidly is known as the cut-in voltage of a diode.
2. This cut-in voltage is very near to the barrier potential. Cut in voltage is also called knee voltage.
3. This is also called the knee voltage or cut-in voltage and it is equal to the barrier potential of the p-n junction.
4. The cut-off voltage is the voltage at which a battery can be considered a fully discharged battery, beyond which further discharge could cause harm.
5. The forward voltage at which the silicon diode starts allowing a large electric current is called cut-in voltage.

Thus, the cut-in voltage for silicon diode is approximately $0.7$ volts.
