After the PN-junction diode was developed in the year 1940s, the diode was first exercised as a high-power rectifier, low-frequency during the year 1952. This increases the amount where pairs of electron-hole can be produced by an occurrence photon. The intrinsic layer between the P-type and N-type regions of the PIN diode enable it to provide properties such as a high reverse breakdown voltage, and a low level of capacitance, and there are also other properties such as carrier storage when it is forward biased that enable it to be used for certain microwave applications. When the PIN diode is connected in forward biased, the charge carriers are very much higher than the level of intrinsic carrier’s attention. The wider intrinsic area also means the PIN diode will have a low capacitance when reverse-biased. The PIN diode comprises of three regions, namely P-region, I-region and N-region. The effect of radiation is modeled as spatially uniform generation of electron-hole pairs within the device. This diode is an ideal element to give electronics switching in applications of electronics. What are Ferromagnetic Materials – Types & Their Applications, The PIN diode is used as a high voltage rectifier. Once fully depleted the PIN diode capacitance is independent of the level of bias because there is little net charge in the intrinsic layer.
