    Hi I want to ask everybody who know this : was the leg notation for base, collector and emitter for BC547 transistor are similar even though they are manufactured by different manufacturer? Thank you

    How about comparing the datasheets?

    Yeah, i tried google it but never found datasheet for this transistor's company except others. And I worried that leg notation for C,B and E would not be same if using other company's datasheet

    It should be the same, as they are meant to be compatible.

    All BC547 (no matter from which the company ) has the same pinout.
    In fact all BC5xxx has the same pinout

    I see... Do all manufacturers follows a standard on every leg's component especially transistor to ease the user?

    No not all transistors have the same pin-out. The golden rule in electronics is to never assume anything. But check with the data sheet. As a good example. The common 7805 regulator is also available in a low power variant. The 78L05. You should think that these have the same pinout. But this is not the case. Not that I have done THAT DUMB mistake ever...[​IMG] But so you do not get confused. A BC547 in the same package will be compatible across manufacturers

    keep the flat surface of the transistor facing towards you... then from right side.. collector base and emitter on the left side..
