Yintoni a PNP-transistor?

Transistors - a izixhobo semi-Umqhubi, apho izigqibo angekho ngaphantsi kwesithathu. Kwiimeko ezithile, bakwazi ukuphucula izakhono ukwenza intlokoma okanye ukuguqula umqondiso. Kukho ezininzi ezahlukeneyo zezi zixhobo, yaye phakathi kwabo - PNP-transistor.

Bathi transistors kwi impahla semiconductor. Yakhiwa lesilicon, germanium, njl

Ukuba transistor kwezi nkalo zintathu kufuneka ezimbini p-uhlobo conductivity, ibizwa ngokuba "transistor kunye conductivity ngqo", okanye "ukudluliselwa transistor PNP". Isixhobo apho kwiingingqi ezimbini Electron conductivity, obizwa ngokuba transistor kunye ukuqhutywa reverse okanye npn yenguqu. Kukusebenza zombini transistors ziyafana, kodwa umahluko ilele kuphela ezichaseneyo.

Apho kuyimfuneko PNP-transistor?

Ngokuxhomekeke kuhlobo iimpawu kumazwe sisendleleni, oko zisetyenziselwa iinjongo ezininzi. Njengoko sele kukhankanyiwe, lo transistor isetyenziselwa isizukulwana, inguqu kunye yokukhulisa imiqondiso yombane. Ngenxa yokuba le ombane igalelo okanye yangoku itshintswa, ulawulo lwangoku ngaphandle yesekethe igalelo wenziwe. utshintsho ezincinane igalelo parameters kukhokelela utshintsho esingakumbi imveliso ekhoyo kunye ombane. impahla yokukhulisa loo isetyenziswa technology analog (unomathotholo, analog TV, unxibelelwano njalo njalo. D.).

Ekuhambeni kwexesha lethu, lisetyenziswa kwi ubuchule analog vuvabyi PNP-transistor. Kwaye nanku omnye candelo libaluleke kakhulu - iteknoloji yedijithali - phantse ngenqaba kwaye isebenzisa intsimi kuphela. Bipolar PNP-transistor wabonakala intsimi ekuqaleni, ngokuba kwayo parlance eqhelekileyo kuthiwa nje transistor.

Yokusebenza kunye Ipharamitha transistors

Transistors eyakhayo wenza kwizihlomelo zeplastiki kunye nentsimbi. Ukuqwalasela iinjongo ezahlukeneyo transistors, ezi zixhobo zikhethwe ngokungqinelana ezithile iparameters. Umzekelo, ukuba transistor okhulisa ezitsho eziphakamileyo, masibe aqhelelkileyo umqondiso yokukhulisa. Ke ukuba transistor PNP esetyenziswa umlawuli lwangoku, kufuneka ube imishini umqokeleli yangoku.

References iqulethe iimpawu eziyintloko transistor:

• Ik - ezisebenza (ubuninzi) umqokeleli yangoku;
• h21e - inzuzo;
• Fgr - ubuninzi frequency yokukhulisa;
• Pk - amandla mbuthi ukusasaza.

phototransistors

Phototransistor - isixhobo novelwano wobhobhozayo ekukhanyeni, leyo irradiates kuyo. Ibhokisi lwezindlu namatywina a transistor injengaleyo, umzekelo, eyenziwe ngeplastiki ngaphaya okanye ngeglasi. Imitha ngalo lingena isiseko bommandla phototransistor. Ukuba lesiseko okufakwe, ngoko abathwali isigxina kwabafundi. Phototransistor ukuvula xa abathwali isigxina angashenxela isiphambuka umqokeleli, kwaye ziya kuhlawulwa isiseko, umqokeleli okhoyo ngoku uya kuba kakhulu.

Ngaphandle transistors abakwazi ngqondweni elektroniki mihla. Phantse akukho isixhobo kakhulu akakwazi ukwenza ngaphandle kwabo. Ebudeni beminyaka yesicelo kunye nophuhliso transistors zitshintshile kakhulu, kodwa umgaqo yokusebenza yabo iyafana.
