Phakathi Izinto ze-elektroniki zihlalutyiwe kule bhulogi sele kukho iintlobo ezininzi ze-transistors, zombini i-bipolar kunye ne-field effect. Ngoku lixesha lokongeza enye kuluhlu, njengoko kunjalo 2n3904, yenye yezona zisetyenziswayo kuninzi lweeprojekthi ze-elektroniki. Kule meko yenye ye-BJT, okanye i-bipolar, kodwa inezinto ezithile ezinomdla ekufuneka uyazi.
Apha uya kuyazi ukuba yintoni kanye kanye, i-pinout yayo, apho unokufumana khona iidatha zedatha, njani ukuthenga enye yazo, kwaye inde njl.
Yintoni i-transistor 2n3904?
El 2N3904 transistor Luhlobo lwe-bipolar transistor, uhlobo lwe-BJT lwesiginali encinci (amandla asezantsi kunye namandla asezantsi, anombane ophakathi). Olu hlobo lwe-transistor yi-NPN, kwaye inezinto ezinomdla ezinje ngokutshintsha ngokukhawuleza (inokusebenza ngokuhamba rhoqo), amandla ombane aphantsi, kwaye ilungele unxibelelwano kunye nokwandiswa.
Uyabona ngaphakathi izixhobo zemihla ngemihla ezinje ngeethelevishini, iiradiyo, ividiyo okanye abadlali beaudio, iiwotshi zekartz, izibane ezibengezelayo, iifowuni, njl.
Esi sixhobo se-transistor siqhelekile. Ibiyi amalungelo awodwa omenzi wechiza yi-Motorola I-Semiconductor kwii-60s, kunye nePNP 2N3906 (iqabane layo). Enkosi kuye, ukusebenza kwandiswa. Kwaye ayibizi, iphakheji ye-TO-92 namhlanje, njengokutshintsha iphakheji yakho yentsimbi endala.
Ewe i-pinout yakho, ungayibona kumfanekiso ongaphambili, ukuba njengesiqhelo kwii-transistors, unezikhonkwane ezithathu ezinamanani ezishiya indawo erhangqiweyo yephakheji ngasemva, oko kukuthi, ukutolika umzobo kunye nokutshatisa le uyiphethe ngesandla ngoku , Kuya kufuneka ubeke indawo ethe tyaba phambi kwakho.
