Lub sijhawm rov qab los ntawm Schottky diodes yog nrawm heev (tab sis mos) cov yam ntxwv rov qab. … Tsis tas li Schottky rectifiers muaj qhov ntsuas kub siab tshaj plaws feem ntau nyob rau hauv thaj tsam ntawm 125 ° C txog 175 ° C, piv rau qhov raug 200 ° C rau cov pa pn junctions uas txuas ntxiv cuam tshuam rau tus cwj pwm tam sim no.
Lub sijhawm rov qab los ntawm Schottky diode yog dab tsi?
Lub sijhawm rov qab los Lub sijhawm hloov pauv yog
~ 100 ps rau lub teeb liab me me, thiab mus txog kaum tawm nanoseconds rau lub zog tshwj xeeb muaj peev xwm diodes.
Puas Schottky diode ua haujlwm nyob rau hauv kev tsis ncaj ncees lawm?
Rov qab bias schottky diode
Thaum qhov thim rov qab kev tsis ncaj ncees yog siv rau lub schottky diode, qhov dav dav nce ntxiv. Yog li ntawd, cov hluav taws xob tam sim no nres. Txawm li cas los xij, ib qho me me tam sim no ntws los ntawm cov thermally zoo siab electrons hauv cov hlau.
Puas yog Schottky diode yog qhov rov qab sai sai?
Schottky barrier diodes (SBDs) tsis muaj PN junctions; Hloov chaw, lawv siv Schottky teeb meem, uas tshwm sim ntawm kev sib tshuam ntawm cov hlau thiab cov khoom siv hluav taws xob xws li N-hom silicon. … Fast-recovery diodes (FRDs) yog PN junction diodes, tab sis yog diodes ceev nrog ib qho kev txhim kho zoo heev.
Kuv tuaj yeem siv dab tsi los hloov lub diode?
Rov qab mus rau koj cov lus nug qub, tsis muaj cov khoom siv hluav taws xob uas tuaj yeem hloov lub diode (p-n junction)tsis yog lwm qhov p-n hlws ris (txawm yog nyob rau hauv ib lub diode, transistor los yog MOSFETpob). Cov khoom no tuaj yeem txhim kho tau thaum siv MOSFET thiab txuas txuas txuas los txo qhov poob.

Puas tau rov qab rov qab handspring?
Lub roundoff back handspring yog ib qho kev ua si gymnastics uas tso cai rau koj siv lub zog los ntawm qhov pib roundoff los tsim lub nraub qaum nrawm thiab muaj zog. Kawm yuav ua li cas thiaj ua tau ob qho kev txav no sib cais ua ntej sim muab tso ua ke.
Koj puas tuaj yeem sib npaug schottky diodes?
1 Teb. Qhov tam sim no yog sib cais ntawm ob qhov kev sib tshuam, yog li txo qis thermal dissipation ntawm txhua tus thiab txhim kho kev ntseeg tau / MTBF. Txij li thaum cov diodes nyob rau hauv tib lub pob, qhov kev pheej hmoo ntawm qhov tsis sib npaug tam sim no yuav muaj tsawg heev, yog li kev xav txog paralleling discrete diodes tsis siv.
Qhov twg yog qhov laj thawj tseem ceeb rau kev thim rov qab / tig rov qab lub tswv yim?
Lub hom phiaj yog txo cov nqi, ua kom cov haujlwm ua haujlwm zoo, lossis ua kom cov nyiaj ntsuab ntws ruaj khov. Peb lub hom phiaj tseem ceeb ntawm kev thim rov qab yog: Txoj Cai Hloov Kho - Qhov no yog lub tswv yim tsim kho dua tshiab. Nws hu kom rov kho cov haujlwm kom tau nyiaj ntau dua lossis tau txais txiaj ntsig.
Koj puas tuaj yeem rov qab tau cov ntaub ntawv tom qab rov ua dua?
Yes! Nws yog ua tau thiab tsis tas yuav txhawj xeeb txog cov ntaub ntawv poob txij li cov ntaub ntawv rov qab los ntawm lub hard drive tom qab rov ua dua tuaj yeem ua tiav nrog kev pab los ntawm kev hard drive cov ntaub ntawv rov qab software los ntawm Remo.
Puas rov tuav pov hwm rov qab xav tau cov neeg tuav pov hwm rov qab?
Cov tuam txhab tuav pov hwm rov qab feem ntau yuav rov ua pov hwm lawv tus kheej, lub sij hawm hu ua retrocession. Ntau txoj cai tau nthuav tawm ntawm ntau tus neeg tuav pov hwm rov qab. Nyob rau hauv rooj plaub no, qhov kev sib pauv yuav koom nrog tus thawj coj rov tuav pov hwm uas yuav sib tham txog cov ntsiab lus ntawm txoj cai uas lwm tus neeg tuav pov hwm rov qab yuav koom nrog.
