i have acer Aspire ES1-432 DA0ZQFMB6F0 which is the mosfet tpca8109 damage...is that possible to replace mosfet TPCA8109 with AO4447A?

Re: replacing mosfet tpca8109
The pinout is the same - both are P-channel.
However, the replacement AO4447A is a lower current device @ 17A vs. the original @ 24A.
Otherwise, yes it will work.
You can try it and monitor the temp of this device. If your logic board consumes < 17A then this replacement part is a valid replacement. -
Re: replacing mosfet tpca8109
No. It is the opposite. The higher the current support, the better the part.
To achieve the higher current support - the Rds value will be lower (this is the resistance is in milliohms). Here, the lower the Rds value, the better the part.
Much like a car - more horsepower, the faster the car can run.
But if the logic board does not consume the high current value then often you can replace with a lower current part. That is, the mosfet is often overrated to be safe and to allow the mosfet to run cooler.
TI has some great mosfets but of course hardly any are available in the current marketplace. Our local rep mentioned that TI is building a new FAB in Texas so their capacity will improve 'soon' and parts will return to a normal flow.Comment

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 -
First of all, I'd like to mention that I'm a novice when it comes to laptop repair, although I do have some experience with soldering.
One day, my laptop experienced a severe stutter, and after rebooting, it failed to boot into Windows. I decided to disassemble it and found that the PL900 component was blown. Later, I came across a post (https://www.badcaps.net/forum/troubl...error%E2%80%99) with the same problem, where...08-30-2024, 06:13 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... -
TLDNR; Have an old SAMSUNG TV with blown hybrid MOSFET/controller IC on power board to be replaced; replaced blown main capacitor on same power board several years ago successfully, and TV has been working fine since until this IC popped all of a sudden. Want to know what if anything to check on board to make sure before replacing and testing with new IC. Have 2 new matching ICs, DIP socket to make removal/replacement easier, a whole other known-good power board with which to compare, if necessary. -
Hi,
Finally got time to fix this board up.
At first it didn't give any POST codes. Turns out it was an unsupported Celeron D cpu. After dropping in an Celery 2.6gHz the CPU came out of reset with clock signal, but still no post codes. For a while it did work when I applied pressure to the ADP3168 chip, but on next reboot the MOSFETs started to burn. Then I left it as is for months.
Now I came back prepared. Replaced the bad MOSFETs and the ADPxx18k drivers. Now I don't get any MOSFETs blowing up issues anymore. But sadly, the Vcore is missing. The whole VRM isn't...
