2n3904: he aha kāu e ʻike ai e pili ana i kēia transistor

2n3904

Ma waena o ua kālailai ʻia nā ʻenehana uila i loko o kēia blog he nui nā ʻano o nā transistors, nā hopena bipolar a me nā hopena. ʻO kēia ka manawa e hoʻohui i kekahi i ka papa inoa, e like me ka 2n3904, ʻo ia kekahi o nā hoʻohana i hoʻohana ʻia i ka lehulehu o nā papahana uila. I kēia hihia he BJT hou aʻe ia, a i ʻole bipolar, akā me kekahi mau ʻano hoihoi loa āu e ʻike ai.

Maʻaneʻi ʻoe e ʻike ai i ke ʻano o ia, kāna pinout, kahi e loaʻa ai nā ʻikepili pūnaewele, pehea e kūʻai ai kekahi o lākou, a lōʻihi etc.

He aha ka transistor 2n3904?

ʻO PJT transistor pinout

El 2N3904 transistor ʻO ia kahi ʻano transistor bipolar, ʻano BJT no ka hōʻailona liʻiliʻi (haʻahaʻa haʻahaʻa a me ka mana haʻahaʻa, me nā uila waena). ʻO kēia ʻano transistor he NPN, a he ʻano hoihoi kona, e like me ka hoʻololi wikiwiki ʻana (hiki ke hana me nā alapine kiʻekiʻe), uila haʻahaʻa haʻahaʻa, a kūpono ia no ke kamaʻilio a hoʻonui.

Hiki iā ʻoe ke ʻike i loko nā hāmeʻa o kēlā me kēia lā e like me nā kīwī, nā lekiō, wikiō a i ʻole nā ​​mea hoʻokani leo, nā uaki quartz, nā kukui uila, nā kelepona, a pēlā aku.

Kūleʻa kēia mea transistor. Ua ___ ia i hoʻoholo ʻia e Motorola Semiconductor i nā makahiki 60, a me PNP 2N3906 (kona hoa). Mahalo iā ia, ua hoʻonui ʻia ka maikaʻi. Hoʻohui, makamae ia, me kahi pūʻulu TO-92 i kēia lā, ma ke ʻano he pani no kāu pūʻolo hao kahiko.

Ma waho o Motorola, ua hana ʻia e nā hui ʻē aʻe e like me Fairchild, ON Semiconductor, Semtech, Transys Electronics, KEC, Vishay, Rohm Semiconductor, Texas Instruments (TI), Central Semiconductor Corp, etc.

Ma ke'ano o kāu pinout, hiki iā ʻoe ke ʻike iā ia i ke kiʻi ma mua, e like me ka maʻa mau i nā transistors, ʻekolu mau kui i helu ʻia e waiho ana i ka ʻāpana poepoe o ka pūʻolo i hope, ʻo ia hoʻi, e wehewehe i ke kaha kiʻi a kūlike i ka mea āu e paʻa ai i kou lima i kēia manawa. , kau ʻoe i ka pālahalaha i mua ou.

Nā hiʻohiʻona a me ka ʻikepili pūnaewele

Inā ʻoe e haʻohaʻo e pili ana i ka hiʻohiʻona hiʻohiʻona o kēia ʻano transistor, eia kekahi o lākou:

  • Kekahi mea: Semiconductor transistor
  • ʻAno: bipolar a BJT paha
  • Pūʻolo: TO-92
  • Polarity: NPN
  • Anakahi uila: 40v
  • Hoʻololi pinepine: 300Mhz
  • Hoʻolaha mana: 625mW
  • ʻO ka mea hōʻiliʻili no kēia manawa pololei: 200mA
  • Kuhi pololei o kēia manawa (hFE): 100
  • Pākuʻi wela hana like: -55ºC a 150ºC
  • Emitter mea hōʻiliʻili - uila uila ma lalo o 300 mV ma Ic = 10mA
  • Nā Pin: 3
  • ʻOkoʻa: NTE123AP

Hoʻoiho i ka ʻikepili

Kahi e kūʻai ai i 2N3904

No kūʻai i transistor ʻO kēia mau ʻano, hiki iā ʻoe ke hoʻohana i nā lawelawe like ʻole o nā hale kūʻai i loea i ka uila, a i ʻole ma nā paepae e like me Amazon. ʻO kahi laʻana, eia kekahi mau ʻōlelo aʻoaʻo:

  • Pahu paʻi Bojack me 250 ʻāpana. Nā Transistors o nā ʻano he nui, i waena o ia ka 2n3904.
  • ʻAʻohe huahana i loaʻa. Loaʻa iā ia kēia pack o 50 anakahi o ka 2n3904.
  • ʻO tooGoo Hāʻawi kekahi i kahi pack ʻē aʻe i ʻoi aku ka maikaʻi a me nā 25 unit o ka 2n3904.

Hoʻopili ka ʻike o ka ʻatikala i kā mākou kumumanaʻo o ka hoʻoponopono hoʻoponopono. E hōʻike i kahi kaomi hemahema ʻaneʻi.
