WebA PIN diode is a diode with a wide, undoped intrinsic semiconductor region between a p-type semiconductor and an n-type semiconductor region. The p-type and n-type regions are typically heavily doped because they are used for ohmic contacts.. The wide intrinsic region is in contrast to an ordinary p–n diode.The wide intrinsic region makes the PIN diode an … Web6.2.1 Diode Characteristics. A p-n junction diode can be used as a switch. When the diode is forward-biased, the switch is said to be in the ON state and when it is reverse-biased, the switch is in the OFF state. Figure 6.1 shows the V–I characteristic of a p–n junction diode. The diode current is given by the relation: where, V is the bias ...
