Kukhona ama-transistor amaningi we-NPN, njenge-2N3045, njll., Kodwa enye yezinto ezaziwa kakhulu nezisetshenzisiwe yile i-2N3055. Le transistor ye-bipolar inhloso ejwayelekile yamasekethe kagesi. Idalwe ngezinqubo ze-epitaxy ukukhulisa izingqimba ze-semiconductor lapho yakhiwe khona bese ifakwa kuphakheji wensimbi.
Ngokuqinisekile alukho ulwazi oluningi mayelana nale divayisi ye-semiconductor, ngoba ayinzima kakhulu, kepha wena sitshela konke odinga ukukwazi ngaye ukuze ukwazi ukuyifaka ekusetshenzisweni kwakho kwesikhathi esizayo kwamasekethe akho namaphrojekthi athakazelisa ngokwengeziwe.
Izici ne-pinout ye-2n3055
Njengabanye abadlulisi, u-El I-2N3055 inokuxhumana oku-3 kwe-emitter, isisekelo nomqoqi. Sesivele sikuxoxile lokhu kwezinye izindatshana ezimayelana nama-transistors. Ngakho-ke, zero ukungabaza mayelana ne-pinout yale transistor ye-NPN. Ukucushwa kungokuphina okungu-1 kwesisekelo, okuzosetshenziswa njengoshintshi wamanje ukudlula ku-semiconductor noma cha, i-pin 2 yi-emitter (evamise ukuxhumeka ku-GND noma emhlabathini), nomqoqi empeleni eyi-TAB ngoba ayikho iphini yesithathu (evamise ukuxhumeka emandleni).
I-2n3055 transistor ingasetshenziswa yamasekethe wamandla aphakathi, iphephile, ine-saturation ephansi phakathi kwamandla okuqoqa-emitter, ukupakisha kutholakala ngaphandle kokuhola, kunenzuzo engaphezu kwe-70 hFE yamanje yamanje (eqondile), amandla amakhulu angakwazi ukuphatha noma ukudlula umqoqi kanye no-emitter ngu-60v we-DC, ngokufana nesikhathi samanje esiphezulu esingadlula kumqoqi ngu-15A ngokuqhubekayo.
Kwesisekelo, imikhawulo iku-7v (base-emitter) naku-7A DC kuzimo zombili. Endabeni ye-voltage phakathi komqoqi nesisekelo, ingafinyelela ku-100v. Uma sibheka izinga lokushisa lapho lingasebenza khona, ububanzi buphakathi Kuyahluka ku- + 65ºC. Ngakho-ke, kusebenza emazingeni okushisa adlulele ngaphandle kwenkinga, into okungeyona yonke imishini ye-elekthronikhi ebekezelelayo, ikakhulukazi uma ubheka izinga lokushisa eliphezulu elisekelwayo. Ngendlela, ngokuqedwa kwamandla, kufinyelela ku-115W, hhayi okuncane ...
Izici Isifinyezo:
- Uhlobo: I-NPN
- Okwesekethe lamandla aphakathi
- Thola ama-70 hFE
- Umqoqi-emitter 60v DC
- Umqoqi wamanje ongu-15 A DC
- I-Base-emitter 7v
- Isisekelo 7A
- Isizinda sabaqoqi 100v
- Izinga lokushisa lokusebenza kuya ku- + 65ºC
- Amandla ancishisiwe 115W
- Ukugoqwa kwensimbi
Kuyalingana futhi kuyaphelelisana
Kukhona ama-transistor alinganayo we-2n3055. Ungazisebenzisa njenge izikhundla ezinjengo-2n6673 no-2n6675. Amanye ama-transistor afanayo kodwa angafani yi-MJ10023, BUX98 ne-BDW51. Ngaphandle kwenkinga ungazisebenzisa kumasekethe akho njengenye indlela, manje, kufanele ufunde ama-datasheet wabo bonke kahle ukuze ubone umehluko ongaba khona, ngoba kungenzeka angafani kwezinye izimo futhi angaveza izinkinga ezimweni ezimbi kakhulu.
Uma uzibuza okuhambisanayo, okungukuthi, okuphambene, ungabona i-MJ2955. Kulokhu, kungu-transistor ocishe abe ngudadewabo, ofanayo ezicini eziningi ezichazwe esigabeni esedlule, kepha yi-bipolar PNP esikhundleni se-NPN. Ukwazi ukuqedelelwa kwesinye isikhathi kungasisiza kakhulu ekwakhiweni kwethu kwesekethe, yingakho sihlala sikufaka kokuthunyelwe kwethu.
Amadokhumenti
para qamba amasekethe akho ngokuphepha futhi ugcine amabanga asekelwayo Kule divayisi, kufanele ubone amasethi wedatha alawa madivayisi. Ingakhiqizwa ngabakhiqizi abahluke kakhulu, futhi bonke banedatha labo ledatha lapho kungahle kube khona umehluko. I-Freescale, i-STMicroelectronics, ne-Siemens bangabanye babakhiqizi abaziwa kakhulu, yize bebaningi.
Ukuze amasekethe wakho wokushintsha amandla wesikhathi esizayo, ama-amplifiers, i-PWM, abalawuli, ama-amplifiers wesiginali, njll. yamasekethe angahlanganiswa ne-2n3055, unga thola ama-datasheet lapha:
- Ama-datasheet ahlukahlukene kusuka kubakhiqizi abahlukahlukene.
- KU-Semiconductor 2n3055: kusukela kwezinye izikhathi sisebenzise i-ON Semiconductor datasheet kwamanye amadivayisi we-elekthronikhi, nayi imininingwane yedatha yale nkampani ye-transistor okukhulunywa ngayo ...
