    Mosfet replacement question

    Hi all,
    I am repairing a TV that has two shorted mosfets. The original mosfets are KEC KF5N50DS, which are not available.
    I am planning to use Vishay SiHD5N50D as replacement. To me, that seems an OK replacement.
    But just making sure before ordering the parts, do you see anything amiss?
    I have attached the datasheets here.

      should be ok, pulsed current rating is lower but continuous is higher. I'd use it.

          There would be no harm in upgrading these parts to, e.g. 9N50s or 13N50s, they will run cooler and last longer, if you are worried about small spec variations.
          Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

              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...

              Dual mosfet replacement help
              by DoOm86
              Hello.
              I have a notebook with a shorted mosfet, it's a E6930 GA8125.
              It seems to be a 30V dual asymmetric N-channel AlphaMos.
              Luckily the notebook is working, so I just need to find a good replacement for this mosfet.

              And here is where I need help!
              It's the first time I have to replace this kind of mosfet, I checked on mouse and I found this: (mouser No) = 512-FDPC5030SG.
              I need your help to be sure is a good replacement or there is another with better compatibility, since I can't find the same exact (just from China).
              Thanks!...

              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              ...
