Schottky diode nyob rau hauv hluav taws xob circuits

Tom qab lub invention ntawm cov thawj semiconductor ntaus ntawv , muaj ntau yam kev soj ntsuam tau soj ntsuam lub thaj chaw ntawm kuj zoo kawg pn hlws ris. Raws li tej zaum koj yuav tau twv, qhov no yog ib qho diode, uas yuav tsum tau pom nyob rau hauv hluav taws xob Circuit Court. Thaum lub sij hawm uas nws tsim, nws tau rau lub caij uas muaj revolutionized thiab hloov tag nrho cov tswv yim hais txog lub neej tom ntej electronics. Tsis tas li ntawd tsis quav ntsej tsis nyob twj ywm thiab lub cuab yeej ntawm nws lawm. Nyob Zener diode thiab Gunn. Txawm yees ua ib lub Schottky diode, muaj nthuav zog. Nws siv nyob rau hauv electronics yog tsis raws li sensational raws li nws tus naas ej "cov kwv tij". Cov khoom tshwj xeeb ntawm no lub caij tau yav tas los lawm thov nyob rau hauv tshwj xeeb circuits thiab tsis lug siv. Qhov ntau nthuav tias lately Schottky diode pib yuav tsum tau siv raws li ib tug tub ntxhais lub caij nyob rau hauv pulsed khoom siv fais fab. Nws ua hauj lwm nyob rau hauv yuav luag tag nrho cov hluav taws xob tsev neeg priboroh: televisions, VCRs, tus kheej computers, laptops, thiab lwm yam

Kev thaj chaw ntawm lub ntaus ntawv muaj qhia nyob rau hauv ib tug tsawg voltage nco thoob plaws lub p-n hlws ris. Nws yog tsawg tshaj li 0.4 volts. Hais tias yog, qhov no parameter nws yog li ze rau ib tug zoo tagnrho lub caij uas yog siv nyob rau hauv cov lus teb. Txawm li cas los, rau ib voltage ntau dua tshaj 50 volts, cov khoom no ploj. Cuaj kaum, tus Schottky diode tau lug siv nyob rau hauv circuits nrog ua hauj lwm amplifiers. Khoom noj khoom haus xws circuits tsis pub tshaj 15 volts DC, uas coj zoo dua tag nrho ntawm lub zog ntawm cov ntaus ntawv. Nws yuav sawv nyob rau hauv lub tswv yim voj ua ib limiting caij los yog mus koom nyob rau hauv lub chaw ua hauj lwm ntawm regulators.

Dhau li no tseem ceeb heev feature, raws li cov voltage nco nyob rau pn hlws ris, lub Schottky diode muaj ib tug uas tsis muaj capacitance. Qhov no tso cai rau nws mus ua hauj lwm nyob rau hauv lub high-zaus circuits. Zoo "tagnrho" yam ntxwv ntawm lub caij tsis distort cov high-zaus teeb liab. Yog vim li cas nws pib mus rau muab tso rau hauv switching khoom siv fais fab, kev sib txuas lus kiag li lawm thiab controllers.

Tab sis nyob rau hauv tas li ntawd mus rau lub zoo qualities yuav tsum tau muab sau tseg thiab disadvantages. Schottky diodes yog rhiab heev txawm luv luv-term tshaj rov qab voltage ntawm lub pub qhov tseem ceeb. Qhov no ua rau cov qhov tso zis caij ntawm lub system. Tsis zoo li lawv silicon "kwvtij", nws tsis zoo. Thermal neej puas ua tog twg los lub ntiaj teb to tsaws ntxhee, los yog mus rau lub "transformation" ntawm lub ntaus ntawv rau hauv tus neeg xyuas pib.

Tus thawj txhaum yuav ua rau tsis ruaj tsis khov lag luam ntawm tag nrho cov hluav taws xob ntaus ntawv. Nws yog ib heev nyuaj mus nrhiav thiab txhim kho. Nrog kev xav txog thermal neej puas, ces, piv txwv li, nyob rau hauv lub switching fais fab mov yuav ua rau kev tiv thaiv lub lag luam ntawm luv luv-Circuit Court. Tom qab hloov cov faulty caij fais fab mov yuav ua hauj lwm zoo.

Niaj hnub nimno kev lag luam ua hwj huam txaus Schottky diodes. Pulsed tam sim no nyob rau hauv xws li yuav ncav cuag 1.2 kÅ. Qhov hluav taws xob tam sim no ntawm ib co hom nce mus txog 120 A. Tej pab kiag li lawm muaj ib tug ntau ntawm cov tam sim no thiab ib tug zoo kev ua tau zoo. Lawv muaj tau ntse siv nyob rau hauv tsev neeg cov khoom siv thiab muaj electronics.
