Swept-out voltage in PIN diode happens when the PIN diode is
  • a)
    Forward biased and the thickness of the depletion layer decreases till I-region becomes free of mobile carriers
  • b)
    Reverse biased and the thickness of the depletion layer increases till I-region becomes free of mobile carriers
  • c)
    Forward biased and the thickness of the depletion layer increases till I-region becomes free of mobile carriers
  • d)
    Reverse biased and the thickness of the depletion layer decreases till I-region becomes free of mobile carriers.
Correct answer is option 'B'. Can you explain this answer?

PIN Diode:
It’s a special type of diode that contains an undoped intrinsic semiconductor between the p-type and n-type regions. The intrinsic layer does not conduct electric current well.
  • PIN Diode is an inferior rectifier but widely suitable for switches, attenuators, etc.
PIN diode with different biasing:
1. Forward Bias:
  • The Depletion region reduces, resulting in the flow of current.
  • Acts as a variable resistance in the forward bias.
  • A High electric field developed across the junction and this speeds up the transport of carriers.
2. Reverse Bias:
  • Width of the depletion region increases.
  • At a certain voltage, the entire intrinsic layer will be swept out of charge carriers. This is called
“Swept out” voltage.
