Zininzi i-NPN transistors, ezinje nge-2N3045, njl i-2N3055. Le bistolar transistor yinjongo ngokubanzi yemijikelezo yamandla. Yenziwe ngeenkqubo ze-epitaxy ukukhula kweengqimba zeemiconductor ezenziwe ngayo emva koko zafakwa kwiphakheji yesinyithi.
Ngokuqinisekileyo akukho lwazi luninzi malunga nesi sixhobo se-semiconductor, kuba ayinzima kakhulu, kodwa wena sixelela yonke into ofuna ukuyazi ngaye ukuze uyongeze kuzalisekiso lwakho lwexesha elizayo kwiisekethe zakho kunye neeprojekthi ezinomdla ngakumbi.
Iimpawu kunye nokuphuma kwe-2n3055
Njengabanye abagqithisi, uEl I-2N3055 inonxibelelwano olu-3 yokukhuphela, isiseko kunye nomqokeleli. Sele sithethile ngale nto kwamanye amanqaku malunga ne-transistors. Ke ngoko, zero amathandabuzo malunga ne-pinout yale transistor ye-NPN. Uqwalaselo lelo lwepini 1 yesiseko, esiza kusetyenziswa njengokutshintshela okwangoku ukudlula kwi-semiconductor okanye hayi, i-pin 2 yi-emitter (edityaniswe kwi-GND okanye emhlabeni), kunye nomqokeleli oyinyani i-TAB kuba akukho pini yesithathu (ihlala iqhagamshelwe kumandla).
2n3055 i-transistor inokusetyenziswa kwimijikelezo yamandla aphakathikukhuselekile, ine-saturation ephantsi phakathi kombane oqokelelayo-emitter, ukupakishwa kufumaneka ngaphandle kokukhokelela, kunenzuzo engaphezulu kwe-70 hFE yangoku ngqo (yomgama), amandla ombane aphezulu anokuphatha okanye adlule kuwo. Umqokeleli kunye ne-emitter yi-60v yeDC, ngokufanayo nobuninzi obukhoyo ngoku obunokudlula kuqokelelo ngu-15A ngokuqhubekayo.
Kwisiseko, imida ikwi-7v (i-base-emitter) kunye ne-7A DC kuzo zombini iimeko. Kwimeko yevolthi phakathi komqokeleli kunye nesiseko, inokufikelela kwi-100v. Ukuba sijonga amaqondo obushushu anokusebenza kuwo, uluhlu luphakathi Ngaba u + 65ºC. Ke ngoko, isebenza kumaqondo obushushu agqithisileyo ngaphandle kwengxaki, into enganyamezeli zonke izixhobo ze-elektroniki, ngakumbi ukuba ujonga ubushushu obuphezulu obuxhaswayo. Ngendlela, ngokuchithwa kwamandla, kufikelela kwi-115W, kungekhona into encinci ...
Isishwankathelo seempawu:
- Uhlobo: NPN
- Kwimijikelezo yamandla aphakathi
- Ukufumana i-70 hFE
- Umqokeleli-okhupha i-60v DC
- Umqokeleli wangoku u-15 A DC
- Isiseko-esikhupha 7v
- Isiseko 7A
- Isiseko somqokeleli 100v
- Iqondo lobushushu lokusebenza ku + 65 toC
- Ukulahla Amandla 115W
- Encapsulation yentsimbi
Iyalingana kwaye iyancedisana
Kukho ezinye zeetransistors ezilinganayo ze2n3055. Ungazisebenzisa njenge Abatshintshi abanjengo 2n6673 kunye 2n6675. Ezinye izinto ezifanayo kodwa ezingafaniyo zii-MJ10023, BUX98 kunye ne-BDW51. Ngaphandle kwengxaki ungazisebenzisa kwiisekethe zakho njengenye indlela, ngoku, kuya kufuneka ufunde iidathashe zonke zazo kakuhle ukuze ubone umohluko onokubakho, kuba zisenokungafani kwezinye iimeko kwaye zinokuvelisa iingxaki kwiimeko ezigabadeleyo.
Ukuba uyazibuza malunga ehambelana, Oko kukuthi, ngokuchaseneyo, ungayibona iMJ2955. Kule meko, iphantse ibe ngudade ojikelezayo, ngokufanayo kwiimpawu ezininzi ezichazwe kwicandelo elidlulileyo, kodwa yi-bipolar PNP endaweni ye-NPN. Ukwazi okugqityiweyo ngamanye amaxesha kunokusinceda kakhulu kuqulunqo lwesekethe, yiyo loo nto sisoloko sikubandakanya kwizithuba zethu.
Maxwebhu
ukuba Yenza iisekethe zakho ngokukhuselekileyo kwaye ugcine uluhlu oluxhaswayo Kwesi sixhobo, kuya kufuneka ubone ugcino lwedatha kwezi zixhobo. Inokuveliswa ngabavelisi abohluke kakhulu, kwaye bonke banedatha yabo yedatha apho kunokubakho iyantlukwano. I-Freescale, i-STMicroelectronics, kunye nee-Nokia zezinye zezona zinto zaziwa kakhulu kubavelisi, nangona zininzi.
Ukuze ikamva lakho lokutshintsha iisekethi, ii-amplifiers, i-PWM, abalawuli, izikhulisi zomqondiso, kunye nexesha elide njl. yemijikelezo enokudityaniswa ne-2n3055, unako fumana iidatha apha:
- Iifomathi ezahlukeneyo evela kubavelisi abohlukeneyo.
- KWI-Semiconductor 2n3055: Ukusukela ngamanye amaxesha sisebenzise i-ON Semiconductor datasheet kwezinye izixhobo ze-elektroniki, nantsi idathabheyisi yale nkampani ye-transistor ekuthethwa ngayo ...
