The pindiode is an alteration of the pnjunction for particular applications. The reverse breakdown voltage is relatively insensitive to the current flowing thought the diode the reverse current. After the pnjunction diode was developed in the year 1940s, the diode was first exercised as a highpower rectifier, lowfrequency during the year 1952. Zener diodes are designed to operate in the reverse breakdown region. The occurrence of an intrinsic layer can significantly increase the breakdown voltage for the application of highvoltage. Diode circuits operating in the reverse breakdown region. Zener diode in may applications, operation in the reverse breakdown region is highly desirable. Schottky diode draw the band diagram valence band, conduction band, fermi energy for a schottky diode with a n doped semiconductor and a p doped semiconductor at zero bias. It is capable of delivering peak currents in excess of one ampere at speeds up to 10 mhz.
Diodes and diode circuits tlt8016 basic analog circuits 20052006 2 3. The performance characteristics of the pin diode depend mainly on the chip geometry and the processed semiconductor material in the intrinsic or i region, of the finished diode. A read is counted each time someone views a publication summary such as the title, abstract, and list of authors, clicks on a figure, or views or downloads the fulltext. Pindioden sind bauelemente mit einer dreischichtstruktur, gekennzeichnet. It is acting as normal diode while forward biasing. A unique feature of the pin diode is its ability to control large amounts of rf power with much lower levels of dc. Abbildung 39 stromfluss bei einer realen pindiode, einfluss des. Assume that interface states pin the fermi energy to the middle of the semiconducting gap at the interface. Packaged pin diodes 1 macom technology solutions inc. Pin diode working characteristics and its applications. Material defects in 4hsilicon carbide diodes request pdf. This article demonstrates how the dh0035 may be applied to driving pin diodes and comparable loads which. A pin diode is a diode with a wide, undoped intrinsic semiconductor region between a ptype. It has a particular voltage known as break down voltage, at which the diode break downs while reverse biased.
