PIN Diode Tutorial Includes: Switches     PIN diodes are three-layer semiconductor diodes consisting of an intrinsic layer separating heavily doped P and N layers. There are a two main structures that can be used, but the one which is referred to as a planar structure is shown in the diagram. Rather than just having a P-type and an N-type layer, it has three layers such as 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. Due to this characteristic, the diode finds number of applications as given below: Rectification; The conversion of alternating current into direct current is known as rectification. A p-n junction diode … The P region and the N-type regions are known to be heavily doped. Q3. It has an undoped intrinsic semiconductor region between p-type and an n-type semiconductor. PIN Diode characteristics & specifications. Although not as widely used as normal PN junction diodes, PIN diodes are nevertheless used in large quantities. PIN Diode Fundamentals . Since it shows a fast response, it is used as high frequency component. Q7. The large width of intrinsic layer imparts the ability to the diode to tolerate high reverse voltage without leading to the … One characteristic of a PIN diode that makes it useful as an RF switch or attenuator is low junction capacitance. When the PIN diode … 4. The PIN diode is a current-controlled resistor at radio and microwave frequencies. This is a fairly common practice in the industry.
