there is not many dualmosfets. reconstruct traces and try any dual nchannel with fair current. i bet it will work -

@dicky96 is currently working on the same board,ask him what the marking is

Re: EPV51 LA-G078P Mosfet Burned Some one Know this Part Number
Hello guys,
I have a burnt PQB12 caused by a short in the charging port. Could you tell me what is the part number please?
And if possible before and after mosfet voltages?
I know this is other person’s thread, but since it was answered already, I thought of here would be better to get some help too.
ThanksLast edited by Sraros; 12-17-2021, 05:03 PM.Comment

Zooming in your PQB13 i can read 74220 and so PQB12 is identical.
Mine in PQB13 is 7506 so I ll go with this. Thanks eitherway for posting your pictures

hi
in a welding machine i had a mosfet and four components wich connect with it burned
i ordered all the damaged components and replace it but when i put the device on the plug all the components burned again i had tested before and i had not shunts
i dont understand whats happen wrong
more particular on the schematic q11p01 mosfet q11p02 tranzistor
three paralel resistors had burned q11p07 zener shunt q11p08 open
when i changed all these shunts q11po7 mosfet and tranzistors
maby the transformer has problem on your opinion or something on...08-19-2023, 01:27 PM -
Dear All
Anybody have experience to repair L13 Gen2 Board Number : LAR-2 PD charger problem?
I have one board the U4201 CSD87501L are burned and the 20V_VBUS_USB2 can't switch to 20V_VINT_IN, after replace this Mosfet it's still very HOT and just use few hours will burned again. i have repeat replace this Mosfet 3 times and all dead.
After that i try to shorted Mosfet Source 1 to Source 2 to bypass the 20V, and found the Control Gate 1 and Gate 2 voltage both are 20v same with 20V_VBUS_USB2.🤨
So did anybody know this case will need to replace... -
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 -
Hi, I have a HP Pavilion x360 - 15-dq0007nc (just about 26 months old) with burned mosfet. Sadly I didn't found any boardview or schematic for this model, so I need your help with this.
The mosfet right next to it is probably SM3319NSQA N-channel.
The burned one is connected to a Sic634 pin 8-11 "Power stage input voltage. Drain of high-side MOSFET" So it should be a P-channel? Can you help me with finding the right replacement?
Also I measured about 15 ohms to the ground on the coil. But I didn't remove the burned stuff yet - it will wait until... -
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.
