    What component is this?

    Hi, this is my firs post on forum
    I'm troubleshooting toshiba l850, i won't start, it's totally dead.
    In main input circuit is this I THINK transistor, but it reads out as shorted, all pins. It's driving n mosfet, and when this thing is on board transistor next to it is shorted in drain source and reverse.
    So, I'm planning to replace it for starters, but i don't know what specs are.. Can someone help?
    Markings are:

    pdque
    fdmc
    9884
    Think it's Fairchild, googled, but I can't find datasheet anywhere.
    It is on the picture...

          You are wrong. That is not FDMC9884, is FDMC8884. N-Channel Power Trench MOSFET 30 V, 15 A, 19 mΩ. This device is used for Power Management and load switching
          applications common in Notebook Computers and Portable Battery Packs.

              Behringer Eurolive B205D repair - help identifying transistor
              by magneh
              Hello
              Got this speaker from a friend , defective. Power led comes on and off , in a loop.
              Disassembled, got the board out, and after a bit of measuring I found a low resistance on a 5v6 line. With a bit of current I found a transistor heating up on that line (labeled T1 and 113 as on pic).
              After removing this guy, I got a value of 0.7 in diode mode on that 5v6 line, which before had 0.02 or something like that.

              I tested powering it up without the IC, and the speaker turns on and stays on, and works fine

              Still, I need to replace this transistor....

              help to identify transistor msi ms-15ck1
              by elsomer
              hi people, i need some help to identify a transistor(q14) that is missing on the board, so the gpu has no voltage i think that q14 activate the phases for gpu, but i dont have schematic or boardview, but i think its the same transistor than q15 and q16, thanks...

              Help with blowing transistor NAD T752 receiver
              by rddube
              Hello everyone,

              I guess I need help from the masters to try and find what is frying a 2SC5669 transistor on the left channel of this front center Amp for a NAD T752.

              Was working perfectly and all of a sudden I heard a pop, and then a glow from the amp. Not only did the 2SC5669 burn a leg, but R520 which is a 220 ohm resistor partially burned - it now measures 110 ohms.

              I bought this amp second hand fairly cheap as it was not working, it went into protection mode. I finally traced it down to the same transistor Q510, the one that just popped. It was shorted...

              by amigo744
              hello there,

              xbox series x hdmi u82 transistor 5 pin,

              can anybody tell me voltages of this transistor in standby and power on mode ???

              on which pin of this transistor are the voltages ?

              regards
