Hiya does anyone know which mosfet this is? If so does anyone know where to find a replacement? As i need to get it replace but i have no idea where to find one,
Thank you
Thank you

Post more details of the motherboard; make; model. Inquiring minds want to know. -

You have many choices, including to use the one mentioned above.
Found a similar schematic - see attached.
Criteria:
1) 3 x 3 smd size
2) N-channel type
3) handle the same or higher currents as the original (use the one in this shared schematic to review the datasheet - use it for reference)
4) handle the same or higher voltages
From where do you like to shop for parts? Digikey / mouser / RS Electronics ok? You are in the UK so you should also have access to Mobile Sentrix (UK branch).
Lowest cost will be from Aliexpress but will take time for delivery.Comment

Thank you so much, yes am from UK but just starting learning to repair electronics items, for my laptop it's my first time that's why i didn't know where to buy them fromYou have many choices, including to use the one mentioned above.

Here is a stock item at DK.

* linked are Canadian $ prices. Change the currency to suit. DK has a fair shipping fee.
* this cross should work fine
Here is a link for Mobile Sentrix (UK) - this part should also be ok but has a lower current rating:

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...09-27-2024, 03:31 AM -
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... -
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... -
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... -
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
