3Mp Old Version... (Philips)

(1/1)

menotbug:
I'm opening my old (1998) dead creative CDRom, and found many 3Mp (SOT323) side-by-side with 1Mp...

checking 1Mp found BC848W which is correct..., but 3M found BCV62 (DUAL PNP in an SOT143B (4 pin)) which is correct too according to BCV62 datasheet...

however, my 3Mp is a SOT323 (3 pin), guessing by transistor numbering scheme, and by still produced siblings (BC847 (NPN) vs BC857 (PNP)), I found this BC858W, and on its datasheet is indeed 3M old version...

you may update your info by adding BC858W as part of 3M series...

Thanks for your help.
Datasheet added.

It's really great what you post up that I understood more easily.
