Kune akawanda maNPN transistors, senge 2N3045, nezvimwe, asi imwe yeanonyanya kuzivikanwa uye anoshandiswa ari iyo 2N3055. Iyi bipolar transistor ndeyezvinangwa zvemaseketi emagetsi. Iyo inogadzirwa kuburikidza neepitaxy maitiro ekukura iwo masemiconductor akaturikidzana ayo ayo akaumbwa uye anozovharwa mune simbi package.
Chokwadi hapana ruzivo rwakawanda pamusoro peiyi semiconductor chishandiso, nekuti haina kuomarara, asi iwe isu tinotaura zvese zvaunoda kuti uzive nezvake kuitira kuti iwe ugone kuzviwedzera mune yako yemberi kuitiswa kwema circuits ako uye zvinonakidza mapurojekiti.
Zvimiro uye pinout yeiyo 2n3055
Kufanana nevamwe vatapuri, El 2N3055 ine 3 kubatana kune emitter, base uye muteresi. Isu takatokurukura izvi mune zvimwe zvinyorwa nezve transistors. Naizvozvo, zero kusahadzika nezve iyo pinout yeiyi NPN transistor. Iyo yekumisikidza ndeyeyepini 1 yebase, inoshandiswa sechinjiso cheiyo yazvino kuti ipfuure nesemiconductor kana kwete, pini 2 ndiyo emitter (inowanzo kuve yakabatana neGND kana pasi), uye muteresi ari iwo chaiwo TAB sezvo pasina pini yechitatu (kazhinji yakabatana nesimba).
2n3055 transistor inogona kushandiswa yemasekete emagetsi ari pakati, yakachengeteka, ine yakadzika kuzadza pakati pemuteresi-emitter magetsi, kurongedza kunowanikwa kutungamira-kusununguka, ine mukana weinopfuura 70 hFE yeiyo yakananga ikozvino (mutsara), iwo akanyanya magetsi ayo anogona kubata kana kupfuura muunganidzi uye emitter iri 60v yeDC, yakafanana neiyo yepamusoro nguva yazvino inogona kupfuura nemuteresi iri 15A ichienderera.
Nezve base, miganho iri pa7v (base-emitter) uye 7A DC mune ese ari maviri kesi. Panyaya yemagetsi pakati pemuteresi nechigadziko, inogona kusvika pa100v. Kana isu tikatarisa tembiricha iyo kwainogona kushanda, iyo renji iri pakati Shanduro ku + 65ºC. Naizvozvo, inoshanda patembiricha yakanyanyisa isina dambudziko, chimwe chinhu chisinga bvumirwe nemidziyo yese yemagetsi, kunyanya kana iwe ukatarisa pakakwirira tembiricha yakatsigirwa. Nenzira, maererano nemasimba ekuparadza simba, inosvika 115W, kwete isina basa ...

- Muteresi wazvino 15 A DC
- Base-emitter 7v
- Nheyo 7A
- Muunganidzi-base 100v
- Kushanda kwekushanda -65 kusvika + 200ºC
- Yakadzimwa Simba 115W
- Metallic encapsulation
Zvakaenzana uye zvinowirirana
Kune mamwe akaenzana ma transistor eiyo 2n3055. Unogona kuvashandisa se vanotsiva vakaita 2n6673 uye 2n6675. Mamwe akafanana asi asiri iwo ma transistors iwo MJ10023, BUX98 uye BDW51. Pasina dambudziko unogona kuishandisa mumatunhu ako seimwe nzira, ikozvino, iwe unofanirwa kuverenga iwo madhateti eawo ese mushe kuti uone misiyano inogona kuitika, nekuti inogona kunge isinga fanane mune dzimwe nguva uye inogona kuunza matambudziko muzviitiko zvakanyanya.
Kana iwe uchinetseka nezve inoenderana, ndiko kuti, zvinopesana, unogona kuona iyo MJ2955. Mune ino kesi, ingangoita hanzvadzi transistor, yakafanana mune zvakawanda zvehunhu hwakatsanangurwa muchikamu chakapfuura, asi iri bipolar PNP panzvimbo yeNPN. Kuziva izvo zvinowedzerana dzimwe nguva zvinogona kutibatsira zvakanyanya muzvikamu zvedu zvematunhu, ndosaka tichigara tichizviisa muzvinyorwa zvedu.
Datasheets
Para nyora matunhu ako zvakachengeteka uye chengetedza iwo akatsigirwa maseru Nezve ichi chishandiso, iwe unofanirwa kuona madhatashiti emidziyo iyi. Inogona kugadzirwa nevagadziri vakasiyana kwazvo, uye vese vane dhatashiti ravo raigona kuve nemisiyano. Freescale, STMicroelectronics, uye Nokia ndevamwe vevanogadzira vanozivikanwa, kunyangwe paine zvakawanda.
Saka kuti yako ramangwana simba switching macircuit, amplifiers, PWM, regulators, chiratidzo ma amplifaya, uye iyo yakareba etc. yemaseketi anogona kunyorwa neiyo 2n3055, iwe unogona tora madhatabheti pano:
- Akasiyana madhata kubva kune vakasiyana siyana vanogadzira.
- PA Semiconductor 2n3055: kubvira dzimwe nguva isu takashandisa iyo ON Semiconductor dhatasheet yemamwe emagetsi zvigadzirwa, heino dhatasheet rekambani ino yeiyo transistor iri mubvunzo ...
