Ci gaban al&39;ummar ɗan adam ba ya rabuwa da kowane fanni na rayuwa, kuma sabuntawar samfuran lantarki daban-daban ba zai buɗe ƙoƙarin mai ƙirar mu ba. A gaskiya ma, mutane da yawa ba za su fahimci abubuwan da ke cikin kayan lantarki ba, kamar MOS. Tube.

MOS bututu yana da hannu a cikin gudanarwa daga yawancin masu ɗauka, wanda kuma aka sani da transistor-pole guda ɗaya. Yana cikin na&39;urorin sarrafa wutar lantarki. Yana da juriya mai girma na shigarwa (10 ^ 7 ~ 10 ^ 12Ω), ƙaramar amo, ƙarancin wutar lantarki, babban kewayon ƙarfi, haɗin kai mai sauƙi, babu abin fashewa na biyu, faɗin yanki mai aminci, da sauransu.

, yanzu ya zama transistor bipolar kuma mai karfin ikon transistor. MOS tubular diode (kuma aka sani da parasitic diode) da aka samu a cikin na&39;urar bututun MOS guda ɗaya, amma babu a cikin da&39;irar haɗin gwiwa. Ana iya amfani da diode a baya kariya da ci gaba da babban tuƙi na yanzu da kuma inductive load.

Yawancin lokaci, matsa lamba na gaba shine kusan 0.7-1V. Tun da diode yana samuwa, na&39;urar MOS ba zai iya fahimtar amfani da sauyawa a cikin kewaye ba kawai.

Misali, a cikin da&39;irar caji, ana yin caji. Bayan cire haɗin wutar lantarki, baturin zai koma baya. Tsare-tsare don amfani da MOS (1) Domin yin amfani da bututun MOS lafiya, iyakar ƙimar ikonsa, matsakaicin ƙarfin magudanar ruwa, matsakaicin ƙarfin tushen ƙofar, da matsakaicin halin yanzu ba a ƙetare a ƙirar kewaye.

(2) Lokacin amfani da nau&39;ikan transistor MOS daban-daban, dole ne a haɗa su zuwa da&39;irar daidai da son zuciya da ake buƙata, kuma dole ne su kula da polarity na MOS transistor. Misali, akwai hanyar haɗin PN tsakanin tushen da magudanar bututun MOS, kuma ba za a iya danna ƙofar tashar N-channel ba. Ƙofar bututun p-tashar ba za a iya nuna rashin tausayi ba, kuma irin wannan turawa.

(3) Tunda abin shigar MOSMOS transistor yana da girma sosai, dole ne a gajarta fil ɗin yayin sufuri da ajiya, kuma dole ne a yi amfani da marufi na garkuwar ƙarfe don hana yuwuwar fashewar ƙofar waje. Yana da mahimmanci a lura cewa ba za a iya sanya bututun MOSMOS a cikin akwatin filastik ba. Zai fi kyau a adana shi a cikin akwatin ƙarfe.

A lokaci guda, kula da juriya da danshi na bututu. (4) Don hana rushewar shigarwar ƙofar bututun MOS, duk kayan aikin gwaji, benches, ironing iron, da kewaye da kanta dole ne su kasance da kyau; lokacin walda, don Allah a fara walda. Kafin da&39;irar haɗin gwiwa, ƙarshen bututu ya kamata a gajarta juna, kuma an cire kayan gajeren lokaci bayan walda; lokacin da aka cire bututu daga tsarin taro, tabbatar da cewa jikin ɗan adam yana ƙasa ta hanyar da ta dace, misali ta amfani da zoben ƙasa.

Tabbas zaka iya amfani. Advanced gas dumama ƙarfe ƙarfe ya fi dacewa don walda bututun MOS don tabbatar da aminci; lokacin da wutar ba a rufe ba, ana shigar da fitilar a cikin kewaye ko daga kewaye. Dole ne ku kula da matakan tsaro na sama lokacin amfani da MOS.

(5) Lokacin shigar da bututun MOS, kula da matsayi na shigarwa don kaucewa kusa da abubuwan samar da zafi; domin ya hana bututu vibration, shi wajibi ne don gyara fitilu gidaje. Lokacin da fil ɗin ya lanƙwasa, diamita ya kamata ya fi girman tushen 5 mm don hana allurar tanƙwara da haifar da zubar iska. (6) Lokacin amfani da VMOS, dole ne a ƙara ma&39;aunin zafi mai dacewa.

Ɗauki VNF306 a matsayin misali, bayan shigar da 140 × 140 × 4 (mm) radiator, matsakaicin ƙarfin zai iya kaiwa 30W. (7) Bayan haɗa nau&39;in tubes a layi daya, tun da ƙarfin da ke tsakanin na&39;urorin lantarki da ƙarfin rarrabawa, girman halayen amplifier ya ƙasƙanci, kuma babban mitar parasitic na amplifier yana da sauƙin faruwa. Sakamakon ra&39;ayi.

Saboda haka, yawanci ba ya wuce 4 composite tubes a layi daya, kuma parasitic oscillation resistor yana haɗa zuwa ƙasa ko ƙofar kowane bututu. (8) Ƙofar tushen wutar lantarki na MOS tube ba za a iya juyawa ba, wanda za&39;a iya adana shi a cikin yanayin budewa. Lokacin da ba a yi amfani da bututun MOS ɗin da aka keɓe ba, saboda yawan juriyar shigarsa, kowane lantarki dole ne a gajarta don hana filayen lantarki na waje.

Lalacewa ga tasirin bututu. (9) Lokacin waldawa, murfin ƙarfe na waje dole ne a sanye shi da waya ta ƙasa ta waje don hana lalacewar bututu saboda ƙarfen lantarki. Dangane da ƙaramin adadin walda, Hakanan zaka iya dumama iron ɗin kafin waldawa kuma cire filogi ko kashe wutar lantarki.

Musamman, a lokacin walda da insulated ƙofar MOS tube, waldi ya kamata a yi a cikin tsari na tushen yayyo kofa, da waldi ya kamata a yanke. (10) Lokacin da aka sayar da ƙarfe na 25W, ya kamata ya kasance da sauri. Idan kuna amfani da ƙarfe na 45 ~ 75W, yi amfani da tweezers don danne tushen fil ɗin don taimakawa zafi.

MOS tube za a iya amfani da qualitatively duba ingancin da bututu da mita juriya fayil (duba tabbatacce kuma baya juriya tsakanin kowane PN junction da juriya tsakanin magudana), da kuma rufi filin sakamako tube ba za a iya duba domin amfani da multimeter, dole ne a yi amfani da Gwaji. Haka kuma, hanyoyin gajeriyar hanya na kowane lantarki za a iya cire su kawai bayan haɗa mai gwadawa. Lokacin rarrabuwa, yakamata ku gaje shi, sannan ku cire shi.

Makullin shine hana ƙofar daga iyo. A taƙaice, tabbatar da amfani da aminci na kulawar MOS, ya zama dole a kula da matakan tsaro iri-iri don zama iri-iri, yawancin ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun masu sana&39;a musamman ma masu sha&39;awar lantarki, dole ne su fara bisa ga ainihin halin da suke ciki. .
