Qhov sib npaug ntawm 2N5551 yog dab tsi?
Tso lus
2N5551 yog ib hom PNP hom transistor siv dav heev thiab siv dav hauv hluav taws xob circuits. Tab sis raws li cov xwm txheej sib txawv, lwm cov qauv yuav xav tau, yog li qhov sib npaug ntawm 2N5551 transistor yog dab tsi?
Tam sim no, muaj ntau hom transistor nyob rau hauv kev ua lag luam uas tuaj yeem hloov 2N5551, ntawm cov uas muaj ntau tshaj yog BC557, BC556, 2N5401, BC327, thiab lwm yam. Cov transistors no zoo sib xws hauv cov hluav taws xob tsis zoo thiab tuaj yeem hloov 2N5551 feem ntau, tab sis lawv kuj pheej yig dua thiab tau yooj yim dua.
Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias txawm hais tias cov qauv hloov pauv no muaj qhov tsis zoo sib xws, nws yog qhov tsim nyog los xyuas seb lawv cov kev ua tau zoo raws li qhov yuav tsum tau ua hauv kev siv tswv yim. Ntxiv mus, cov xwm txheej sib txawv ntawm daim ntawv thov thiab cov kev xav tau ua haujlwm yuav xav tau cov qauv sib txawv kom ua tiav cov txiaj ntsig zoo.
Lub 2N5551 transistor yog ib qho uas nquag siv NPN hom transistor nrog qhov nce siab. Tshwj xeeb, nws DC tam sim no amplification coefficient hFE tuaj yeem ncav cuag ntawm 70 thiab 400 nyob rau hauv kev ua haujlwm zoo. Nyob rau tib lub sijhawm, cov yam ntxwv siab zaus ntawm cov transistor kuj zoo heev, nrog rau kev ua haujlwm ntau dua 500MHz, ua rau nws siv dav hauv RF circuits thiab amplification circuits.
