Vreau sa stiu si eu un echivalent pt un BC108. Am fost la magazin si mi-a dat un echivalent BC556 dar nu sunt sigur ca e echivalent. Voi ce ziceti?

BC108 este tranzistor NPN iar BC 556 este tranzistor PNP deci nu sunt echivalenti.BC546 poate fi folosit in loc de BC108.

bc108 poate fi inlocuit cu bc546, merge si cu bc547; sunt asemanatori; 546 si 547 au tensiunea CE mai mare decat BC108 deci nu trebuie sa-ti faci griji din privinta asta.

Am gasit prin tranzistoarele care le am eu prin casa un BC107A. Il pot folosi?

in principiu da.(bc109 era considerat la vremea lui tranzistor hi-fi, in special versiunea cu C la coada... avea amplificare mai mare... ) :yawinkle:

daca nu ma insel acel BC108 (la fel si 107, 109) are capsula metalica. Deci nu prea ai echivalenti in privinta disiparii termice.
