    K0389 K0392 MOSFET Pinout question

    Hi guys
    I need to order some K0389 and K0392 Mosfets for a GPU repair

    When I look up the datasheets I find these

    K0389 - https://pdf1.alldatasheet.es/datashe...JK0389DPA.html

    K0392 - https://pdf1.alldatasheet.com/datash...JK0392DPA.html

    But you will see these are different packages and both the K0389 and K0392 off my PCB have the same package (same as K0392 in the above datasheets)

    I can find both MosFETs on ALI

    https://www.aliexpress.com/item/3256...archweb201603_

    https://www.aliexpress.com/item/3290...archweb201603_

    But I can't see clearly what I am getting. I don't understand why the K0389 datasheet does not match the device I have.

    So what to order?

      Are you sure its an 8 and not a B . This might be it,same package WPAK(3F)



      order part number: RJK03B9DPA-00-J5A

                  Cheers, Yeah I ordered both types of MOSFET and also the APW7088 VRM controller from SUHMS, so I saved a bit on postage. I've used that supplier before, they seem OK

                      Intel D865PERL - no Vcore after replacing MOSFETs and MOSFET drivers
                      by kotel studios
                      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...

                      How do you test MOSFET in laptops ?
                      by Jane
                      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                      ...

                      Asus X712EA 3 volts after the first mosfet
                      by AppleLover123
                      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...

                      ASUS ROG Zephyrus GPU Mosfet repeat failure
                      by MicroSMD Lab
                      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...

                      Asus GA502D keeps blowing mosfet
                      by Scotchmist
                      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
