Mene ne wani pnp-transistor?

Transistors - a wasan kusa da na shugaba na'urorin, a cikin abin da babu kasa da uku karshe. A wasu yanayi, za su iya bunkasa damar don samar da vibrations ko maida da sigina. Akwai da yawa daban-daban kayayyaki daga wadannan na'urori, da kuma tsakanin su - pnp-transistor.

Rarraba transistors a kan wani semiconductor abu. Suna Ya sanya daga silicon, germanium, da dai sauransu

Idan transistor na uku yankunan da biyu p-type watsin, shi ne ake kira "transistor tare da kai tsaye watsin", ko "transfer transistor pnp". An na'ura a wadda yankuna biyu sun electron watsin, ake magana a kai a matsayin transistor tare da wani kuma baya da kade-kade ko mika mulki npn. Aiki duka biyu transistors ne guda, amma bambanci ta'allaka ne kawai a cikin polarity.

Inda m pnp-transistor?

Dangane da abin da irin halaye a sufuri kasashen, ana iya amfani da dalilai da dama. Kamar yadda aka ambata riga, da transistor da ake amfani da zamani, da canji da kuma karawa da na'urar sakonni. Saboda gaskiya cewa shigar da ƙarfin lantarki ko yanzu aka canza, yanzu iko ne da za'ayi na shigar da kewaye. Kananan canje-canje a cikin shigar da sigogi kai zuwa wani ma fi girma canji a cikin fitarwa halin yanzu da kuma irin ƙarfin lantarki. Irin wannan karawa dukiyar da ake amfani a analog fasahar (rediyo, analog TV, sadarwa da sauransu. D.).

A zamaninmu, shi ne amfani da akwatin tilbijin na analog dabara bipolar pnp-transistor. Kuma a nan ne wani muhimmanci sosai bangare - dijital fasahar - kusan ƙi shi, kuma yana amfani da kawai filin. Bipolar pnp-transistor bayyana da yawa a baya filin, saboda shi a cikin na kowa parlance ake magana kawai a matsayin transistor.

Performance da sigogi na transistors

Transistors na gaskiya sanya a roba da karfe enclosures. Idan akai la'akari da daban-daban dalilai na transistors, wadannan na'urorin da ake zaba bisa ga wasu sigogi. Alal misali, idan wani transistor domin karawa da high mitoci, shi dole ne a high mita siginar karawa. Kuma idan pnp transistor amfani a halin yanzu kayyadewa, ya kamata da wani babban aiki da yanzu haraji.

phototransistors

Phototransistor - a na'urar kula da haske juyi, wanda irradiates shi. A shãfe haske gidaje akwatin irin wannan transistor yi, misali, Ya sanya daga m roba ko gilashi. Radiation ta hanyar shi shiga tushe na phototransistor zone. Idan tushe ne irradiated, sa'an nan da cajin yan dako ake generated. Phototransistor bude a lokacin da cajin yan dako motsa a cikin haraji Junction, kuma mafi za a rufe sansanin, da haraji, yanzu za su zama gwaji.

Ba tare da transistors ba zai iya kwatanta zamani lantarki. Kusan babu tsanani na'urar ba zai iya yi ba tare da su. A lokacin da shekaru na aikace-aikace da kuma cigaban transistors sun canza muhimmanci, amma manufa na aiki ne guda.
