sorry i don't have any pictures of it. it's a samsung brand notebook. based on the datasheet that you have given the top mark wasn't the same.

Shoot a laptop model number and number of transistor (PQXX or QXX). That will help a lot.Laptops and computers repair.Comment

Re: mosfet with 6908a top mark?
sorry people i forgot to check the link given by budm... on the given link the logo is the same so it's AON6908A, are there any other equivalent that can be use as a replacement?. i can't find the exact component.Comment

Thanks. Any other fets that can be use as replacement? Like getting from junk laptop mainboard?Comment

Re: mosfet with 6908a top mark?
yes you can do that however you will need to find the data sheet on the mosfet your gonna use as a donor and make sure it matches the burned mosfet your gonna replace so do a side by side comparison of both datasheets to make sure they are internally the same i have used ones higher rated then the one i am gonna replace it with and it always have worked fine...just can't go lower rating...Comment

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

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
After i found a shorted mosfet i still want to give it a try at replacing it ........
The references on the mosfet are 6962 and GAOC14 but i cant seem to find those on the internet.
Do you have any idea of a "known" mosfet that could be equivalent ?
Thanks
