    XORB48 or AO3800a

    Hi,

    Friend of mine has a drone that he crash it on the grass…
    Now one motor doesn't work, I separate test motors and everything works ok, but if I start it one the motors doesn't work, I took mosfet from other motor to the motor that doesn't work, and now works…


    I search then in my country but I don't find them, they are not producing anymore…

    Can some help me with something similar ?
    Can I find this mosfet on computer boards?

    It's about N-channel type , 30v , 3 pads smd

    Thanks!
    Stefan

      AO is Alpha & Omega, so you can get a datasheet and find a better part

          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          ...

          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...

          HP 15-fc0007ca Charger Cycling On/Off with Hot MOSFET – Need Component Info
          by Tomylee
          Hello,
          I have an HP 15-fc0007ca that works normally, but when I plug in the charger while the laptop is powered on, the charging cycles on and off repeatedly—it starts charging, stops, then starts again.

          Using a thermal camera, I identified a MOSFET that is overheating, along with a small 2R2 resistor next to it that gets even hotter than the MOSFET.

          I also hear a “zpzpzpzp” type noise, but the noise is not coming from the same area as the hot MOSFET. I will include a photo with the exact spot where the noise is coming from highlighted.

          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...

          Asus X712EA 3 volts after the first mosfet
          by AppleLover123
          Hey guys,

          i have a asus motherboard here and as the title says after the first mosfet (in the picture) there is nothing more than 3.15v.
          I injected 19v and max. 1 amp at the charging port and there is not voltage drop or smth. It's just taking 19v and 1 milliamp.
          Then i tried to inject 19v and max 1amp after the current sensor and there it first takes 19v and 4 milliamps and after 2 seconds it is taking nothing (no current).
          I measured on the coils on board everything seems fine. Also the main power rail is not shorted (infinite resistance).
          Now i thought something...
