Answer (Detailed Solution Below)
Reverse biased and the thickness of the depletion layer increases till I-region becomes free of mobile carriers
Detailed Solution
Download Solution PDFPIN 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:
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.
Reverse Bias:
1) Width of the depletion region increases.
2) At a certain voltage, the entire intrinsic layer will be swept out of charge carriers. This is called
“Swept out” voltage.
