The PN photodiode and the PIN photodiode are two of the most common formats for photdiodes. A PIN diode is a 3-layer device composed of p region, n region and intrinsic region. From the above expression, it is clear that capacitance and distance are inversely proportional. The particles have exactly the same effect. PIN Diodes PIN diodes are used as current-controlled resistors at RF and microwave frequencies, with resistances that can range from a fraction of an ohm when forward biased, or on, to greater than 10 … PN & PIN photodiodes     However, the thickness is greater on the i region as compared to n region. The figure below represents the symbol of PIN diode: Here, p region denotes the anode terminal and n region denotes the cathode terminal. P region is formed by doping trivalent impurity to the semiconductor. In the case of planar structure, a narrow (thin) epitaxial layer is imposed on the intrinsic region in order to form a P+ region. This region is nothing but serves as the depletion region between P and N regions. The PIN diode … PIN photodiode are also used as nuclear radiation detectors.
