Ho na le likhopolo tse ngata tse ncha ho theknoloji ea transistor. Lintho tsena tse ncha li u thusa ho feta mathata a khale. Baenjiniere ba sebelisa silicon-germanium (SiGe) ho etsa hore li-transistors tsa PNP li sebetse ka potlako. Sena se thusa ho haha li-microprocessors tse potlakileng le li-memory chips. Heterojunction bipolar transistors (HBTs) ke mohato o mong o moholo. Ba u fa phaello e eketsehileng hona joale le liphello tse molemo ho lipotoloho tse khethehileng.
Li-transistors tsa Silicon-germanium PNP li thusa ka mesebetsi e phahameng haholo.
Heterojunction bipolar transistors (HBTs) e fana ka phaello ea hajoale le liphetho tse ntle ho lipotoloho tse khethehileng.
U tla bona mehopolo e mecha ea transistor ha baenjiniere ba leka ho etsa hore lisebelisoa li be nyane hape li potlake. Liphetoho tsena li tla thusa ho etsa moloko o latelang oa li-microprocessors le li-memory chips. Ha u ithuta ka theknoloji e ncha ea transistor, u ikopanya le lefats'e leo mehopolo e mecha e sa khaotseng.
Lula u labalabela ho tseba ka theknoloji ea transistor. Mohopolo o mong le o mong o mocha o thusa ho etsa hore lisebelisoa tsa elektroniki li be bohlale le ho ba matla.
Ha o khetha NPN kapa PNP transistors, nahana ka lebelo le hona joale. Li-transistors tsa NPN li ntle bakeng sa ho fetoha ka potlako le ho sebetsana le hona joale. Li-transistors tsa PNP li thusa ho lokisa le ho haha lipotoloho habonolo. Sheba mofuta oa motlakase oa hau, oa hona joale, le oa sensor pele u khetha. Kamehla hlahloba bukana bakeng sa lintlha tsa bohlokoa. Li-transistors li sebelisoa haholo ha lisebelisoa li ntse li fokola le ho potlaka. U tla fumana mekhoa e mecha ea ho sebelisa li-transistors ho lisebelisoa tsa elektroniki tse tlang.

Phapang e kholo lipakeng tsa NPN le PNP transistors ke efe?
U sebelisa li-transistors tsa NPN bakeng sa ho teba hona joale le li-transistors tsa PNP bakeng sa ho fumana hona joale. Li-transistors tsa NPN li bulela ka motlakase o motle. Li-transistors tsa PNP li bulela ka motlakase o mobe oa base. Mefuta ea NPN e fetoha kapele hobane lielektrone li tsamaea kapele ho feta masoba.
A na u ka nkela transistor ea NPN sebaka ka transistor ea PNP?
U ke ke ua li fapanyetsa ka ho toba. Li-transistors tsa NPN le PNP li na le lithapo tse fapaneng le phallo ea hona joale. Haeba u batla ho e fetola, u tlameha ho e fetola moralo oa potoloho le pontšo ea polarity. Kamehla hlahloba moralo oa hau pele u etsa liphetoho.
Hobaneng lipotoloho tse ngata tsa dijithale li sebelisa li-transistors tsa NPN?
U bona li-transistors tsa NPN lipotolohong tsa dijithale hobane li fetoha ka potlako mme li sebetsa hantle ka logic e thehiloeng fatše. Lielektrone li tsamaea kapele, kahoo mefuta ea NPN e sebetsa dipontsho tsa lebelo le hodimo betere. Sena se etsa hore lisebelisoa tsa hau tsa digital li tšepahale le ho sebetsa hantle.
U ka hlahloba joang haeba transistor e sebetsa?
U ka sebelisa multimeter ka mokhoa oa diode. Sheba khanyetso pakeng tsa setsi le lithapo tse ling. Bakeng sa NPN, base-emitter le base-collector ba lokela ho bontša ho theoha ha motlakase. Bakeng sa PNP, fetola li-probe. Tlosa transistor haeba u bona 'malo o mokhuts'oane kapa o bulehileng.
U lokela ho khetha transistor ea PNP neng?
U khetha transistor ea PNP bakeng sa ho chencha ka lehlakoreng le phahameng kapa ha mojaro oa hau o hokahana le phepelo e ntle. Mefuta ea PNP e sebetsa hantle lipotolohong tse hlokang ho fumana mohloli oa hona joale. Li boetse li thusa ha lets'oao la hau la taolo le lebisitsoe fatše.
