2n3904: zomwe muyenera kudziwa za transistor uyu

2n3904

Pakati pa zida zamagetsi zosanthula mu buloguyi pali kale mitundu ingapo yama transistors, onse ochititsa munthu kusinthasintha zochitika komanso mphamvu zakumunda. Ino ndi nthawi yowonjezera ina pamndandanda, monganso 2n3904, yomwe ndi imodzi mwazomwe zimagwiritsidwa ntchito kwambiri pama projekiti ambiri amagetsi. Poterepa pali BJT ina, kapena ochititsa munthu kusinthasintha zochitika, koma ndi zina zosangalatsa zomwe muyenera kudziwa.

Apa mudzadziwa kuti ndi chiyani kwenikweni, pinout yake, komwe mungapeze mahedeti azipangizo, kugula chimodzi mwa izo, ndi zina zazitali.

Kodi transistor 2n3904 ndi chiyani?

Kutsitsa kwa BJT

El 2N3904 transistor Ndi mtundu wa bipolar transistor, BJT mtundu wa siginecha yaying'ono (kutsika pang'ono ndi mphamvu zochepa, yokhala ndi ma voltages apakatikati). Transistor yamtunduwu ndi NPN, ndipo ili ndi mawonekedwe osangalatsa, monga kusintha mwachangu (kumatha kugwira ntchito ndimafupipafupi), magetsi otsika kwambiri, ndipo ndioyenera kulumikizana ndi kukulitsa.

Mutha kuwona mkati zida za tsiku ndi tsiku monga ma TV, mawailesi, makanema kapena ma audio, mawotchi a quartz, nyali za fulorosenti, matelefoni, ndi zina zambiri.

Chida ichi cha transistor ndichofala kwambiri. Zinali chovomerezeka ndi Motorola Semiconductor m'ma 60s, komanso PNP 2N3906 (mnzake). Ndiyamika kwa iye, kuchuluka kwawonjezeka. Kuphatikiza apo, ndiotsika mtengo, ndi phukusi la TO-92 lero, m'malo mwa phukusi lanu lakale lachitsulo.

Kuphatikiza pa Motorola, idapangidwa ndi makampani ena ambiri monga Fairchild, ON Semiconductor, Semtech, Transys Electronics, KEC, Vishay, Rohm Semiconductor, Texas Instruments (TI), Central Semiconductor Corp, etc.

Koma pini yanu, mutha kuziwona m'chifaniziro cham'mbuyomu, kuti monga zimakhalira mu transistors, muli ndi zikhomo zitatu zowerengedwa zomwe zimasiya gawo lozunguliralo la phukusi kumbuyo, ndiye kuti, kutanthauzira zojambulazo ndikufanana ndi zomwe mwagwira m'manja tsopano , muyenera kuyika chipinda chathyalacho patsogolo panu.

Komwe mungagule 2N3904

Para kugula transistor Mwa izi, mutha kugwiritsa ntchito malo osiyanasiyana m'masitolo apadera pamagetsi, kapena papulatifomu monga Amazon. Mwachitsanzo, nazi malangizo:


Zomwe zili m'nkhaniyi zikutsatira mfundo zathu za malamulo okonzekera. Kuti mufotokoze cholakwika dinani Apa.
