Re: 8030/8039mosfet
See attached. Nothing special.
Each is a N-channel mosfet in a 5*6mm package. Find a high current version (low on resistance) and the same part can be used for both replacements. -
Re: 8030/8039mosfet
Not intierly, one is P channelComment

Re: 8030/8039mosfet
Which one? Can you link or share the datasheet of the mosfet in question / schematic for this logic board?Not entirely, one is P channelComment

Re: 8030/8039mosfet
8030 = N channel
8039 = P channelComment

Re: 8030/8039mosfet
The above linked datasheet for 8039 states it is an N-channel.
Do you have any topside markings you can post? From the internet searches, the 8039 part is N-channel.Comment

Re: 8030/8039mosfet
Can you post pics of the bottom side as well?
These do not look like mosfets.Comment

Re: 8030/8039mosfet
Are mosfets SURE, 8 pins, 4 on one side common and a heatpad connected to Drain
Repaced by Sisa18 the N_channel ofcourseAttached FilesLast edited by Dinneke; 11-15-2022, 03:21 PM.Comment

Re: 8030/8039mosfet
How did you conclude this mosfet is a p-channel ?
Never mind..found the datasheet. Indeed it is P-channel. Strange that Toshiba has the same part #, yet N-channel.Last edited by mon2; 11-15-2022, 03:00 PM.Comment

I know how mosfets work....thanks for the datasheet

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... -
Hello, I have a problem with a Medion notebook.
https://www.medion.com/de/service/pr...etail/30030203
MEDION AKOYA S15450 (MD 63650) A-DE N MSN: 3003 0203 with Windows 10 64x
The keyboard makes random entries and I don't seem to be the only one. Someone on this board has the same problem. I had BIOS version 207 installed and the BIOS version that Medion Support offers here as 209.

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...
