    Component identification - SOT23 MOSFET

    Hey, I'm having a hard time finding a replacement for this IC, pretty certain it is a mosfet, but I need to know what kind. It relays about 20VDC as a part of charge circuit. I have identical one on this board that is blown due to short.


    Sorry I couldn't get it right side up under the microscope for the photo, the board is still a part of a large soundbar that I barely fit under it anyway.



    Thanks!

      could be 2sk425 or 2sk94-1 related
      if your sure it's a fet.

      if not then maybe a bft93

          Looks very simiplar to Alpha & Omega AO3401A 30V 4Amp P-Channel MOSFET

              Bingo, that is it. I even have AO3401 in stock for replacement, marked A19T.

              Thanks for the help!

                  How do you test MOSFET in laptops ?
                  by Jane
                  I tried to use this method:

                  Testing an N-channel MOSFET:

                  Step 1: Discharge the Gate (turn off the MOSFET)
                  Place the black probe (COM) on the Source (S) and the red probe on the Drain (D). The multimeter should show no continuity (high resistance or "OL" – open line).
                  Then, touch the black probe to the Source (S) and the red probe to the Gate (G). This discharges any stored charge in the Gate, turning the MOSFET off.

                  Step 2: Charge the Gate (turn on the MOSFET)
                  Now, place the red probe on the Gate (G) and the black probe on the                  ...

                  Asus VG278 mosfet identification ?
                  by guizmo1967
                  Hello,

                  My Asus monitor stop working today !! I found the problem on the main board, the power supply board is ok. It's Q9, a mosfet but I have no idea what are the specs since I don't have the schematic for that monitor !!

                  Can someone help me identified this mosfet ?

                  Thank you !

                  VGA MOSfet permanently shorted and loss of MOSfet pad
                  by Nooy
                  Hello everyone, I recently found this badcaps site and super Learn Electronics Repair youtube channel. And I wanted to learn how to troubleshoot power supplies and VGA cards and how to practice soldering, since I already have a properly defective piece of them. I am currently trying to solve two problems:

                  I have a Gigabyte GV-RX460WF2OC-4GD type card. I managed to find the faulty MOSfet (AON6414A) on it, which I replaced. The card starts up, but after about half a minute, the MOSfet in the same position will be shorted again. Is it possible that the PWM controller driving the MOSfet...

                  Mosfet Identification on Rog G513QY
                  by eastcoastcomputing
                  Hi Guys, I'm trying to identify that mosfet to replace it. Any help would be appreciated. I've checked the IC Markings and Datasheet section but I can't match the brand logo with any of the pictures. I thought maybe Alpha Omega because of the greek symboles or maybe Sinopower as the logo vaguely looks like an S...

                  It is on the motherboard of an Asus ROG G513QY (Motherboard ref: G713-6050A3254002-MB-A01).

                  Thaks! ...

                  Hi guys;

                  I need to replace two MOSFET's, the full number is

                  P21N03REOE4206; I have attached a Picture; Does anyone maybe know the UM? maybe OUM ? Logo for the manufacturer?

                  Please and Many thanks as always;...
