Diode Schottky in wareeggeedii korontada

Ka dib markii la alifay ee ugu horeysay ee qalabka Semiconductor , cilmi badan ayaa baaritaan sifooyinka Isgoyska pn weyn. Sida laga yaabo in aad ku qiyaasay, tani waa diode caadi ah, kuwaas oo loo arki karaa in wax kasta oo circuit electronic. Waqtiga ay abuurtay, waxa ay ahayd element in galisay iyo bedelay oo dhan fikrado ku saabsan korantada mustaqbalka. Sidoo kale iska indho ma sii iyo technology ee ay wax soo saarka. Muuqday diode Zener iyo Gunn. Xitaa abuurtay diode Schottky ah, wuxuu leeyahay sifooyin u xiiso badan. Its isticmaalo korontada ma ahaa sida cajiib ah sida uu "walaalo" caanka ah. The guryaha gaarka ah ee element this ayaa hore u codsatay in wareeggeedii gaar ah oo aan si weyn loo isticmaalo. The more xiiso leh in waayadan Schottky diode bilaabay in la isticmaalo sida element a muhiimka ah ee awoodda korontada pulsed. Waa in ka shaqeeya ku dhowaad dhammaan priboroh electronic qoyska: telefishannada, fiidiyowga, maykrowayfka, kombiyuutarada shakhsi, laptops, iwm

guryaha gaarka ah ee qalabka waxaa lagu muujiyey in dhibic danab yar yahay ee guud ahaan Isgoyska p-n ah. Waa wax ka yar 0.4 volts. In uu yahay, dhimaya this waa sida ku dhow inay element ugu fiican ee loo isticmaalo in xisaabinta. Si kastaba ha ahaatee, at danab a ka badan 50 volts weyn, guryaha, kuwaas oo ay ka lumaan. Si kastaba ha ahaatee, diode Schottky ayaa si weyn loo isticmaalaa in wareeggeedii la Sammeecado hawl. Cuntada wareeggeedii sida aan ka badnayn 15 volts DC, jidaynayey in ay ka faa'iidaystaan buuxa oo ka mid ah sifooyinka qalabka. Waxa uu in loop-celin ku taagnaan kari waayeen sida element a la yareeyo ama inay ka qaybgalaan shaqada ee xakameeya.

Ka sokow feature muhiimka ah, sida dhibic danab isgooyska pn ah, diode ku Schottky ayaa capacitance hooseeyo. Tani waxay u ogolaaneysaa isaga in ay ka shaqeeyaan in ay wareeggeedii ee hirka sare. Shiidaa sifooyinka "fiican" ee element ma xumeeyaan signal ah ee hirka sare ah. Taasi waa sababta uu bilaabay inuu ku riday bedesheen Koronto, qalabka isgaarsiinta iyo ilaaliyaal.

Laakiin marka laga soo tago in tayada wanaagsan waa in la ogaadaa iyo khasaaraha. dioska- Schottky yihiin kuwo aad u xasaasi u ah xitaa waqti-gaaban danab dambe xad-dhaaf ah oo ka mid ah qiyamka la ogolyahay. Tani waxay keenaysaa in element saarka nidaamka ah. Si ka duwan ay Silicon "walaalo", uusan soo kabsan. burburka kaamerada keenaysaa sidoo kale in ay hadda baxsiga dhulka, ama u "Isbadal" qalab galay kaari ah.

Qaladka ugu horeysay waxay keeni doontaa in hawlgalka aan degganayn ee qalabka oo dhan electronic. Waa arrin ay adag tahay in la helo iyo hagaajin. Iyadoo la tixgelinayo burburka kaamerada, ka dibna, tusaale ahaan, ee korontada bedesheen waxay keeni doontaa in hawlgalka ilaalinta -circuit gaaban. Ka dib markii uu bedelay korontada element khaldan shaqayn doonaa ganaax.

warshadaha casriga ah soo saarta dioska- Schottky awood ku filan. hadda Pulsed in qalabka sida ay gaari karaan 1.2 ka. hadda Constant korontada ka mid ah noocyada gaadho 120 A. qalab noocan oo kale ah waxay leeyihiin tiro balaadhan oo ah hadda iyo qaab ciyaareed wanaagsan. Waxa ay si guul leh loo isticmaalay qalabka guryaha iyo qalabka korontada warshadaha.
