    Mosfets

    Hi

    I have looked but cant seem to find the answer can I use 13n50 to replace a AV2 18n50?

    Secondly what about a AV2 1850 with a FDA18N50?

    I have looked at the datasheets that are available but they are very similar in spec?

    thanks in advance

      Harman Kardon sub TS11 (ds15 amplifer) blows fuse and mosfets
      by BlackScreen_22
      Hi, I'll start by saying that I'm not an expert and I've reached a point where I don't know what to try/do anymore...
      Starting from the beginning: I opened this subwoofer for the first time with a very strong smell of burnt electrical components, I realize that on the amplifier board there is a hole between V+ OUT and GND about the size of a finger, the damaged components were the shorted mosfets, two damaged zener diodes and two capacitors. I bought everything, I fixed the hole by cutting the pcb and putting a piece of a perforated board.
      I had no problems connecting mosfets and capacitors,...

      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...

      Gainward Phantom GTX 980 - mosfets w/ integrated driver NCP5369
      by flerre
      Hi!

      Managed to get a Gainward Phantom GTX 980 in an auction for a bin with components.
      No video out so I started fault finding and found a blown fuse for 3 mosfets. Started checking for shorts and found what I think is a short through all of those 3 mosfets; 0.1 ohms between "VIN" input and "VSWH" output. All mosfets in this gpu are the same ones (NCP5369) with integrated drivers and when I tried measuring the other ones through these ports they were somewhere in the kilo-ohms range.

      So, could I safely assume all of these 3 mosfets are...

      Lenovo Ideapad 15IIL05, turns on and off with charger BUT works by injecting 20v after main mosfets
      by NanoTesting
      I got a 15-IIL05 that failed to turn on BUT IT DID TRY TO TURN ON and then turned off after 30+- seconds, i disassembled it and found a screw loose inside the case.
      With charger it turns on, fan spins but gives no image.
      Tested main mosfets no short, tested 3.3v,5v,DRAM, CPU etc and they were present.
      Reflashed BIOS, same problem.
      Replaced both main mosfets.
      Checked main mosfets again and i noticed that they closed once the laptop shut down, so i decided to bypass them and used a bench PSU to check how much power the laptop was drawing while trying to turn on, 20v@3A,...

      Pioneer VSX-859RDS with all mosfets gone
      by debruina
      Hi,

      I am working on a pioneer VSX-859. It started with only one problem but i ended up with a lot more. Probably caused by me

      Anyway it started with a DSP NG message on the display. That one was easy and was caused by a bad 5v rail. Replaced the capacitors and the message was gone. Everything seems to be working except for a blob sound every time i switched from source. Eventually i tracked that down to a leaking battery on the analog board. Repaired some via's and lines and everything worked ok. That same circuit also caused a not working DCdetect protection. ...
