    Need help finding mosfet manufacturer

    Hi all.
    I'm having a problem trying to identify a fet on my board. the pic shows a different chip than mine but it's the manufacturer I need.My chip is B07 N03 ELA1406.
    Anyone help please.

              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...

              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...

              ASUS ROG Zephyrus GPU Mosfet repeat failure
              by MicroSMD Lab
              The board number is GU502DU. I repaired this a couple weeks ago and it came back with the same issue, same mosfet failed (PQH9201). I'm hoping that the GPU was spared this time.
              I used the same replacement part (purchased from Mouser) and I'm certain the soldering was done properly since it took just as much effort to remove as before. What could cause this same mosfet to fail? I'm thinking if it was unsuitable then the others would fail too. I looked for similar failures on YTube and the mosfet was replaced with AOE6930 in one instance and AOE6932 in the other but it's possible that the...

              Asus GA502D keeps blowing mosfet
              by Scotchmist
              I have an Asus GA502D, it had a blown mosfet which I replaced and the laptop booted into windows, a few mins later it shut off, the same mosfet was blown. I thought maybe just a bad mosfet but same thing happened again, a few mins in windows and shuts off.

              I have removed the mosfet and can run the laptop no problem

              The MOSFET is FDPC5018SG

              Can anyone point me in the direction of what could be the cause of this, could it be the controller rt3663bc?

              Thanks
