General purpose PIN diode Rev. Symbol of PIN diode: First, we connect the diode to the battery and the light bulb with the diode pointing in the same direction as the current flow out of the battery. The construction of this diode has an intrinsic (normal) layer between the n- and the p-sides. AN 979, Handling and Bonding of Beam Lead Devices. Typically, both the P and N regions are heavily doped. A thick intrinsic layer is present between p and n regions. A p-n junction diode is a basic semiconductor device that controls the flow of electric current in a circuit. The improved version of the normal P-N junction diode gives the PIN diode. A p–i–n photodiode, also called PIN photodiode, is a photodiode with an intrinsic (i) (i.e., undoped) region in between the n- and p-doped regions.
