Menene transistor 2n3904?

Farashin transistor na BJT

El 2N3904 transistor Wani nau'in transistor ne mai bugun jini, nau'in BJT don ƙaramin siginar (ƙaramin ƙarfi da ƙaramin ƙarfi, tare da matsakaicin ƙarfin lantarki). Wannan nau'in transistor ɗin NPN ne, kuma yana da wasu halaye masu ban sha'awa, kamar sauyawa da sauri (yana iya aiki tare da madaidaiciyar madaidaiciya), ƙarancin ƙarfin jikewa, kuma ya dace da sadarwa da haɓakawa.

Kuna iya gani a ciki na'urori na yau da kullun kamar talabijin, rediyo, bidiyo ko mai kunna sauti, agogon ma'adini, fitilun kyalli, tarho, da sauransu.

Wannan na’urar transistor ta zama ruwan dare. Ya kasance mallakar Motorola Semiconductor a cikin 60s, tare da PNP 2N3906 (abokin sa). Godiya gareshi, ingantaccen aiki ya karu. Plusari, yana da arha, tare da fakitin TO-92 a yau, a matsayin madadin tsohon kunshin ƙarfe.

Baya ga Motorola, wasu kamfanoni da yawa sun kera shi kamar Fairchild, ON Semiconductor, Semtech, Transys Electronics, KEC, Vishay, Rohm Semiconductor, Texas Instruments (TI), Central Semiconductor Corp, da sauransu.

Game da pinout dinka, kuna iya gani a hoton da ya gabata, cewa kamar yadda aka saba a cikin transistors, kuna da fil uku masu lambobi masu barin ɓangaren da aka tattara na kunshin zuwa baya, wato don fassara zane da dacewa da wanda kuka riƙe a hannunku yanzu , yakamata ku sanya sashin lebur a gabanku.
