2n3904: yini okufanele uyazi ngale transistor

2n3904

Phakathi kwe izinto zobuchwepheshe zihlaziyiwe kule bhulogi sekuvele kunezinhlobo eziningana ze-transistors, zombili i-bipolar nomphumela wensimu. Manje yisikhathi sokungeza enye ohlwini, njengoba kunjalo ne- 2n3904, okungenye yezinto ezisetshenziswa kakhulu kunqwaba yamaphrojekthi we-elekthronikhi. Kulokhu kungenye i-BJT, noma i-bipolar, kepha inezici ezithile ezithokozisayo okufanele wazi.

Lapha uzokwazi ukuthi yini ngempela, i-pinout yayo, lapho ungathola khona amadathasethi wedivayisi, uyithenga kanjani eyodwa yazo, nokunye okude.

Kuyini i-transistor 2n3904?

I-BJT transistor pinout

El 2N3904 transistor Luhlobo lwe-bipolar transistor, thayipha i-BJT yesiginali encane (amandla aphansi namandla aphansi, anama-voltages aphakathi). Lolu hlobo lwe-transistor yi-NPN, futhi inezici ezithile ezithokozisayo, njengokushintsha okusheshayo (kungasebenza ngamaza aphezulu), amandla we-low saturation, futhi ilungele ukuxhumana nokukhuliswa.

Uyabona ngaphakathi amagajethi ansuku zonke njengamathelevishini, imisakazo, ama-video noma ama-audio player, amawashi e-quartz, amalambu we-fluorescent, izingcingo, njll.

Le divayisi ye-transistor ivame kakhulu. Bekuyi ilungelo lobunikazi yi-Motorola I-Semiconductor kuma-60s, kanye ne-PNP 2N3906 (umlingani wayo). Ngenxa yakhe, ukusebenza kahle kwandisiwe. Futhi, kushibhile, kunephakheji ye-TO-92 namuhla, njengokufaka esikhundleni sephakeji lakho elidala lensimbi.

Ngaphezu kwe-Motorola, yenziwe ezinye izinkampani ezinjengeFairchild, ON Semiconductor, Semtech, Transys Electronics, KEC, Vishay, Rohm Semiconductor, Texas Instruments (TI), Central Semiconductor Corp, njll.

Kepha i-pinout yakho, ungayibona esithombeni esedlule, ukuthi njengokujwayelekile kuma-transistors, unezikhonkwane ezintathu ezinenombolo ezishiya ingxenye eyindilinga yephakeji emuva, okusho ukuthi, ukutolika umdwebo bese uqondanisa naleyo ophethe ngesandla sakho manje , kufanele ubeke ingxenye eyisicaba phambi kwakho.

Ungathenga kuphi 2N3904

para thenga i-transistor Kulezi zici, ungasebenzisa izinsizakalo ezahlukahlukene zezitolo ezikhethekile ku-elekthronikhi, noma kuzingxenyekazi ezifana ne-Amazon. Isibonelo, nazi izincomo:

  • Isikhwama seBojack esinezingcezu ezingama-250. AmaTransistors ezinhlobo eziningi, phakathi kwawo kukhona i-2n3904.
  • Ayikho imikhiqizo etholakele. Inayo nale phakethe lamayunithi angama-50 we-2n3904.
  • I-TooGoo Ibuye inikeze elinye iphakethe elishibhile futhi linamayunithi angama-25 we-2n3904.

Okuqukethwe yi-athikili kunamathela ezimisweni zethu ze izimiso zokuhlelela. Ukubika iphutha chofoza lapha.
