    Hello to all ,

    I am searching all the entire internet to find two parts i want for a circuit that cames to me but with no
    any results.

    I do not know more about electronics and i want these two parts .....

    if i am wright the first part is a diode and wrights AF9J if i am not wrong as i see on top and the second is a rectifier?

    Any help please i will appreciate.

    Unfortunately what you see there are not part numbers in the traditional sense, but "top marks." Due to the very small size of SMD parts they are mostly marked with a special code. The code itself is typically detailed on the device data sheet and will uniquely identify the part and sometimes even data of manufacture and country of origin. However, without knowing the device you can't see the
    data sheet, and AFAIK there is no searchable data base to recover the part number.

    Some electronics here tell me that the first is a double diode
    and the second maybe a diode i did not know anything else.
    hope to find something from the Bsomer links

    any further help appreciated.

    xmm i think that it is difficult to have any better picture of that..

    i have scan this before but is it not too big to see.

    the two parts is the one at the center as you see and the other one
    down of it

    hope this helps

    no unfortunately it does not enlarge much more because you can not see anything.
    these are used in circuit that takes 3v and makes it output until 6v and also it outputs
    watt too
