Schottky diode ezifundeni kagesi

Ngemva kokusungulwa ngowokuqala kudivayisi Semiconductor , abacwaningi abaningi baye baphenya property omkhulu PN okuhlangana kuyo. Njengoba kungenzeka uye ukuyichaza, lena diode evamile, okuyinto kungabonakala iyiphi wesifunda electronic. Ngesikhathi eyasungulwa ngaso, kube wukuthola ulwazi kanye isici esiye sashintsha futhi washintsha yonke imibono mayelana electronics esizayo. Futhi indiva angahlali futhi ubuchwepheshe ukukhiqizwa yayo. Uvele Zener diode futhi Gunn. Ngisho wasungula diode Schottky, anezakhi ezithakazelisayo. Ukusetshenziswa Its e electronics sasingeyona ukuthusa ngokuthi "bafowethu" yakhe edumile. I anezakhi ezikhethekile kwalesi sakhi uke isetshenzisiwe ezifundeni ezikhethekile futhi kungukuthi asetshenziswa kabanzi. I mnandi ukuthi muva nje Schottky diode waqala ukuba lisetshenziswe njengeHholo isici core e pulsed segezi. Isebenza cishe yonke indlu priboroh electronic: amathelevishini VCRs, computer, ama-laptops, njll

izakhiwo Specific zedivayisi kuboniswa-low voltage iconsi ngaphesheya kwalapho p-n. Kuyinto engaphansi kuka 0.4 volts. Okungukuthi, lokhu ipharamitha kunjengoba eduze isici ekahle ukuthi isetshenziswa izibalo. Nokho, ngokuhamba kwesikhathi voltage mkhulu kunezinhliziyo volts 50, lezi izakhiwo elahleka. Noma kunjalo, diode Schottky iye kabanzi izifunda nge yokukhulisa umsindo tekusebenta. Ukudla izifunda ezifana ingeqi 15 volts DC, ukuvumela ukuthatha ngokugcwele izakhiwo zedivayisi. Wayema kumjikelezo impendulo njengoba isici nokukhawulela nobe ahlanganyele umsebenzi nabalawuli.

Ngaphandle lesi sici esibalulekile, njengoba iconsi voltage at kwalapho PN, le diode Schottky has a capacitance ongaphakeme. Lokhu kuvumela ukuba basebenze ezifundeni ephezulu imvamisa. Cishe izici "enhle" timphawu akuthuntubezi isiginali ephezulu imvamisa. Yingakho waqala ukubeka e ukushintsha amandla kagesi, amadivaysi zokuxhumana futhi abalawuli.

Kodwa ngaphezu izimfanelo ezinhle kufanele kuphawulwe kanye nobubi obuthile. Schottky diodes ebucayi kakhulu ngisho short-term ngokweqile reverse voltage lamanani ovumelekile ukuphi. Lokhu kuholela element okukhipha kohlelo. Ngokungafani Silicon zabo 'abafowabo', lokhu akusho ukuthi alulame. ukuwohloka Thermal kuholela noma emhlabeni ukuvuza imisinga, noma lowo muntu "ashintshe" zedivayisi ku umqhubi.

Iphutha lokuqala kuzoholela ukusebenza engazinzile yonke idivayisi electronic. Kunzima ngempela ukuthola futhi silungise. Ngokuphathelene ukuwohloka ezishisayo-ke, isibonelo, i- ukushintsha ukuphakelwa kukagesi kuzoholela ukusebenza ukuvikelwa isekhethi. Ngemva esikhundleni okuyiphutha isici ugesi izosebenza kahle.

umkhakha Modern ukhiqiza ngokwanele amandla Schottky diodes. Pulsed samanje zinsizakuphila ongafinyelela 1.2 KA. Njalo kagesi yezinye izinhlobo zobu ifinyelela 120 A. Amadivayisi anjalo kufanele anhlobonhlobo wamanje kanye ukusebenza okuhle. Aye asetshenziswe zasendlini kanye electronics zezimboni ngempumelelo.
