    Mosfet 28N03 substitute

    Hi to all!

    I want to know, if somebody knows, with wich mosfet can i replace 28n03 (i´ve didn't found it like that)

    VDS= 30 V, ID = 28 A RDS(on) < 18mΩ @ VGS = 10 V RDS(on) < 30mΩ @ VGS = 4.5V

    Thx in advance!

          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          ...

          burned mosfet wich has written on top "I6 GUE 8v1507"
          by Caly411
          Hi, Im having a similar problem with my Acer Nitro 5 AN517 52, took it to repair and they said that the problem was a burned mosfet wich has written on top "I6 GUE 8v1507".
          There is written PQB12 on the motherboard right next to it.
          Does anyone know if there is soemthing similar I can buy to replace it with?
          Seems impossible to find theidentical mosfet online.

          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...

          Help identifying mosfet on Razer Blade RZ09 (CH570_MB_NT)
          by redbaron1007
          I have a Razer laptop (RZ09 MB# CH570_MB_NT) that has a shorted mosfet marked BND M03 E067 that I'm unable to find anywhere online. Does anyone either know what the part number is for this mosfet or have a schematic I can find it in?

          Backstory on the whole thing the laptop was plugged into a lamp at a hotel. The lamp got unplugged while it was charging and now the system won't power on anymore. I found the caps around this mosfet shorted and when I injected voltage into the caps the mosfet got hot and my bench psu was pulling 5A. Pretty sure this is all that's wrong with the laptop...

          Find substitute for mosfet in servo board of versacamm sp-540v plotter
          by edugimeno
          Hi There!
          I am currently serviciing a plotter versacamm sp-540v
          I found a shorted mosfet labeled J553 which corresponds with SJ-553s (surface mount)
          Neither local stores nor other webpages that are able to provide it before 1 month (only aliexpress, with 1 month delivery) can provide this part
          I need to find a substitute for it. Can anyone give me a hint on a part that I can use to replace it?

          Also, given the schematic Im attaching (pg 36, transsitor Q1) , does it make sense that the whole machine won't turn on when I press the POWER button on the panel? This...
