Structure and Working of a PIN Diode
A PIN diode, quick for Positive-Intrinsic-Negative diode, has a 3-layer semiconductor shape. The layers are:
- P-Type Layer (Positive): The top layer of the diode is the p-type semiconductor material, which is definitely doped with impurities. This layer is answerable for the fine terminal of the diode.
- Intrinsic Layer: Positioned within the middle, the intrinsic layer is an undoped or lightly doped semiconductor region. It is essential to the diode’s operation, performing as a variable resistor in response to an outside voltage.
- N-Type Layer (Negative): The backside layer is the n-type semiconductor material, negatively doped with impurities. This layer paperwork the negative terminal of the diode.
These layers create a PIN structure, with the intrinsic layer sandwiched among the p-type and n-type layers.
