sursa atx 450w p4

Recommended Posts

Va salut! Am la reparat o sursa de 450w atx p4. Am gasit crapat in doua tranzistorul din chopper bu5027s. Pe schema este figurat un C5027s,care conform datasheetului de pe net este un bipolar,dar in schema este trecuta fotografia unui mos-fet cu canal n. Stie cineva ce este acest BU5027S,daca este un mos-fet sau un bipolar,si daca are un echivalent ca sa il inlocuiesc? Multumesc mult!!

Am inteles. Vreo schema are cineva de la aceasta sursa pe care scrie atx 450w p4? Am gasit o schema pe net, dar are in primar un c5027 si e figurat ca mosfet. Pe poarta mosfetului c5027s este conectat colectorul unui un bipolar c1815. Multumesc mult!! M-am edificat nu este schema corecta cea in care este mosfetul.Trebuie sa gasesc o schema corecta pt. aceasta sursa. Are cineva?
