Diode Capacitance Quiz

Diffusion capacitance is dominant in a diode when it is:

• Reverse biased

• Unbiased

• Forward biased

• Zero biased

Transition capacitance in a diode is also known as:

• Storage capacitance

• Barrier capacitance

• Depletion capacitance

• Both B and C

The diffusion capacitance is proportional to:

• Reverse voltage

• Rate of change of reverse current

• Forward current

• Junction temperature

As reverse bias voltage increases, the transition capacitance:

• Increases

• Remains constant

• Decreases

• Becomes zero

In a PN junction, which region contributes to transition capacitance?

• Neutral region

• Depletion region

• Ohmic contact

• Diffused layer
