    It might be a dual mosfet like a Alpha & Omega AO6402A

      It might be a single mosfet, are pins 1,2,5,6 connected together?
      Is that number 4T6V ? is there a dash above the V ?

        hi, thanks for your answer
        YES 1,2,5,6 are connected together on the pcb.
        YES i read 4T6V but coulnd'nt find nothing with this code.
        NO, i can't see any dash above the V.. but on the side there is what seems "1B"

              I guess my chosen word went wrong. "seem".

              Come here on Great Forum not only want to learn electronics, but also I've want to learn to be good on conversation/writing on post. Sometimes i didn't really understand if without help g**gle translate, sometime the translator make more worst as well.

                mosfet does not switch on when 3v are applied to gate. so i have no ground to my motor.
                btw thanks to all for the answers.
                i wonder how you could identify this component, since i tried on smd lookup marking codes table and found nothing.
                thanks again

                sometimes our english is not the best i know, (i am not english native too.. ) but i hope we can understand each other

                  Mostly 99% work on laptop repair, from there i knowing alpha omega's mosfet. Also have several time see mark with "dash" and number/letter with orientation anticlockwise 90 degree on the end body package. BUT totally newbie at all, that's way reading many threads for learn.
