The transistor - nheyo semiconductor michina

Transistor - nhengo kuti amplification, chizvarwa, uye nekuti rokutendeutsa magetsi oscillations. Transistors muri mhando mbiri: nedambudziko uye munda.

Nechirwere transistor - a semiconductor mudziyo zvinosanganisira maviri PN junctions. Zvokuvamba transistor kuvakwa pamusoro negermanium sekristaro, ine prongs zviviri: ane emitter uye muteresi, izvo chokuita sekristaro pamusoro, vakanyarara kubva umwe kubudikidza chinhambwe 20-50 microns. Mune mamwe mazwi, mumwe wetsoka rinobatanidza emitter kusvika nechigadziko (inonzi emitter mhesano), uye wechipiri - the nomuteresi pamwe chawo (inonzi nomuteresi Junction). Nedambudziko transistors vari rakakamurwa mhando mbiri: pnp uye npn.

Munda zvazviri transistor - munhu semiconductor mudziyo, izvo inotongwa kusiyana dzesango, mukusiyana kune dambudziko okunze, uko goho pari kunotemwa nokuchinja mazano ano. Field mano vari odnozatvornymi uye mnogozatvornymi.

Schematic dhayagiramu of transistor riri pamufananidzo pazasi. Scheme nechirwere chaikosha chinhu pfupi-mutsetse hwaro, rinomiririra nechigadziko, iyo panguva 60 ⁰ uye 120 ⁰ rinosanganisira miviri diagonal mitsetse, mutsetse nomuseve - chiri emitter, wechipiri - the nemuteresi. mirayiridzo museve inoratidza mhando mudziyo. Museve achinongedzera Database - ichi transistor pnp mhando kwefuma - npn. Perpendicular kune mujinga mutsetse - zvaiva electrode. The kukosha zvemagetsi conductivity ari emitter kuziva kuti zvakanaka kubatanidza transistor kuti simba rive. Chiridzwa pnp kutaipa mashoko muteresi uye chawo zvakakodzera kupa akaipa voltage transistor uye npn mhando - akanaka. FETs ari chati zvinoratidzwa sezvinotevera: suwo akaita nokuputsanya vanoratidza, yakafanana mugero sechiratidzo, kuti conductivity pamusoro mugero anomiririrwa miseve wakaiswa pakati kunobva wopedza. Kana museve pfungwa nenzira kupa, zvinoreva kuti chinhu ndezvevanhu N-mhando, uye kana ari negwara, ipapo peji-mhando. Image munda maturo transistor ine gwara induction anosiyana pfupi kurohwa matatu. Kana munda mudziyo ane masuo wandei, avo pfupi dashes zvinoratidzei, wokutanga mutsetse suwo nguva dzose akaisa pamusoro kuwedzera kunobva mutsetse.

In mhedziso, tinoisa kuti ari transistors vasiri pakarepo vakaramba zita, pakutanga akavadanira semiconductor triodes (zvakafanana chubhu michina). Saka kuti transistor - a transistor, inova controllable Kufananidzira, chichiri kushandiswa nokuchinja uye amplifying matunhu. Kushaya kukura, kuvimbika, zviduku kukura uye mutengo - izvi zvakanakira chikuru mano izvi, nokuda iyo transistors vaigona dislodge kubva matavi mazhinji unyanzvi Vacuum sepombi. The chikuru mukana semiconductor mano ndiyo kushaya inopisa cathode, izvo unopedza simba chinokosha, uyewo vanowana nguva anodziya. Mukuwedzera, transistor iri shoma zvikuru pane yemagetsi rambi uye anokwanisa kushanda panguva yakaderera voltage. Izvi zvose akabvumira kuti kuderedza kukura kwezvinhu zvemagetsi.
