You may also want to check out these topics given below! One significant application of diodes is to convert AC power to DC power. More Electronic Components: The PIN diode receives its name from the fact that is has three main layers. A device that uses batteries will likely contain a diode that protects it when battery is inserted improperly. As High Voltage Rectifier: PIN diode is used as high voltage rectifier. A PIN diode has a central un-doped, or intrinsic, layer, forming a p-type/intrinsic/n-type structure. The P and N regions are there and the region between them consists of the intrinsic material and the doping level is said to be very low in this region.  The thickness of the intrinsic layer is very narrow, which ranges from 10 – 200 microns. Connectors     Rather than just having a P-type and an N-type layer, it has three layers such as Tunnel diode can be used as a switch, amplifier, and oscillator.
