Diodes A diode is a simple electronic component which blocks current in one direction and allows it in the other. The PIN diode comprises three regions, namely the P-region (p-type semiconductor), I-region (intrinsic semiconductor) and N-region (n-type semiconductor). This is so because applied forward potential reduces the depletion width. It has an undoped intrinsic semiconductor region between p-type and an n-type semiconductor. From the above expression, it is clear that capacitance and distance are inversely proportional. The intrinsic region offers very high resistivity of the order of 0.1 Ω-m.

This is so because the doping level of N region is very much higher than I region. In case a forward voltage is provided to the diode, the charge carriers from p and n region are injected into the intrinsic region. A PIN diode is a 3-layer device composed of p region, n region and intrinsic region. Usually, its value is -2V. Due to this, the magnitude of the electric field also becomes large.
