Yuav ua li cas yog ib tug pnp-transistor?

Transistors - ib tug semi-neeg xyuas pib pab kiag li lawm, nyob rau hauv uas tsis muaj tsawg tshaj li peb cov lus xaus. Nyob rau hauv tej yam teeb meem, lawv yuav txhim khu lub peev xwm ua kom muaj deeg los yog hloov lub teeb liab. Muaj ib tug ntau ntawm txawv designs ntawm cov pab kiag li lawm, thiab nrog lawv - pnp-transistor.

Cais transistors rau ib tug semiconductor khoom. Lawv yog ua los ntawm pob zeb ntais, germanium, etc.

Yog hais tias cov transistor ntawm peb qhov chaw muaj ob p-hom conductivity, nws yog hu ua "transistor nrog lawv conductivity", los yog "hloov lwm lub tsev transistor pnp". Ib apparatus nyob rau hauv uas ob cheeb tsam tau electron conductivity, xa mus rau raws li ib tug transistor nrog ib tug rov qab tsim los yog kev hloov npn. Khiav lag luam ob transistors yog tib yam, tiam sis qhov txawv lus dag nyob rau hauv lub polarity.

Qhov uas siv tau pnp-transistor?

Nyob ntawm seb dab tsi zoo ntawm cov yam ntxwv nyob rau hauv pib lub teb chaws, nws yuav siv tau rau ntau lub hom phiaj. Raws li twb tau hais, cov transistor yog siv rau cov tiam, transformation thiab amplification ntawm hluav taws xob Pib ntsais koj teeb. Vim lub fact tias lub tswv yim voltage los yog tam sim no yuav hloov, tam sim no tswj yog nqa tawm ntawm lub tswv yim Circuit Court. Me hloov nyob rau hauv lub tswv yim tsis ua rau ib tug txawm ntau dua kev hloov nyob rau hauv lub tso zis tam sim no thiab voltage. Tej amplification cuab yeej yog siv nyob rau hauv analog technology (xov tooj cua, analog TV, kev sib txuas lus thiab hais txog. D.).

Nyob rau hauv peb lub sij hawm, nws yog thov rau analog txheej txheem bipolar pnp-transistor. Thiab ntawm no yog lwm tseem ceeb heev sector - cov technology - yuav luag tsis kam nws thiab siv tsuas teb. Bipolar pnp-transistor nyob npaum li cas lawm teb, vim hais tias nws nyob rau hauv ntau parlance raug xa mus rau cias li ib tug transistor.

Performance thiab tsis muaj lub transistors

Transistors raws kev ua nyob rau hauv hnab yas thiab cov hlau Certificate. Xav qhov sib txawv hom phiaj ntawm transistors, cov pab kiag li lawm yog xaiv raws li tej yam tsis. Piv txwv li, yog tias ib tug transistor rau amplification siab frequencies, nws yuav tsum muaj ib tug loj teeb liab amplification. Thiab yog hais tias lub pnp transistor siv nyob rau hauv lub tam sim no regulator, nws yuav tsum muaj lub siab khiav hauj lwm tam sim no collector.

References muaj lub ntsiab yam ntxwv ntawm cov transistor:

• Ik - kev khiav hauj lwm (nyiaj pab ntau tshaj) collector tam sim no;
• h21e - nce;
• Fgr - tshaj plaws zaus amplification;
• Pk - collector dissipation lub hwj chim.

phototransistors

Phototransistor - ib tug ntaus ntawv rhiab rau lub teeb flux, uas irradiates nws. Lub kaw tsev nyob lub thawv uas xws li ib tug transistor ua, piv txwv li, ua los ntawm cov pob tshab yas los yog iav. Tawg ntawm nws nkag mus rau hauv paus ntawm lub phototransistor tsam. Yog hais tias yog lub hauv paus yog irradiated, ces tus nqi muaj yog generated. Phototransistor qhib thaum them nyiaj nqa tsiv mus nyob rau lub collector hlws ris, thiab ntau yuav tsum tau them puag, rau collector tam sim no yuav tsum tau ntau yam pauv loj.

Tsis muaj transistors yuav tsis xav txog tej yam niaj hnub electronics. Yuav luag tsis muaj teeb meem loj ntaus ntawv yuav tsis ua tsis tau lawv. Thaum lub sij hawm hauv lub xyoo ntawm daim ntawv thov thiab kev loj hlob ntawm transistors tau hloov ho, tab sis lub hauv paus ntsiab lus ntawm lawv lub lag luam yog tib yam.
