De ce esti lenes?

2n5551: BFQ22, BFR39, BFR25. BC538-6, BFR41, BFQ91, BF391, BC538-16, BCX49 si multe altele disponibile la http://www.datasheetarchive.com/search. ... 0&q=2n5551

 

2n5401: imi e lene sa mai scriu o parte din ei... http://www.datasheetarchive.com/search. ... 0&q=2n5401

 

Din linkurile alea navigheaza in continuare pe urmatoarele pagini si vei gasi mai multi echivalenti.

2N5551: npn 180Vc-b/160Vc-e/0,6A/0,31W/Beta:80-250/10mA.BC639: npn 80Vc-b/80Vc-e/1A/1W/Beta:40min/150mA.BC639-6: npn 100Vc-b/80Vc-e/1A/0,8W/Beta:40-100/150mA.BC639-10: npn 100Vc-b/80Vc-e/1A/0,8W/Beta:63-160/150mA.BCX49: npn 80Vc-b/80Vc-e/1A/0,625W/Beta:50min/100mA.De aici se vede ca 2N5551 e mult mai sus cu tensiunea si mai sensibil la amplificare.Echivalenti mai buni ar fi BF466,467,468,666,667,668, ptr ca au si tensiunea mare (200-300Vc-b si 150-250Vc-e), 1A, 2W si Beta 40min/10mA.

Da da am pus un 2n3904 ca altu nu aveam vad ca isi face treaba dar cam frige tranzistorul.Aplicatia in care se foloseste e un amplif auto cu mosfet si are driverul din 16 tranzistori tip 2n3904 2n3906 2n5551 2n5401.Oricum va multumesc fain am sa merg luni si iau un 2n5551 si pun ca ala e original si nu se incalzeste.Imi place la nebunie cum suna ampliful asta se aud perfect inaltele fata de TDA2050 sau alte TDA-uri ma gandesc sa incerc sa fac si eu IPA300 modificat ptr 800Wati cu IRFP264N si driverul de comanda al mosurilor.
