    MOSFET Equivalent

    I found 2 shorted mosfets on a power supply from a SONY LCD tv. The writing on the MOSFETS was K4096, or 2SK4096-

    Digikey told me this part would work

    I just want to know if everyone agrees with the replacement part.

      there's probably a lot of FETs that'll handle it but I'd try and find one that's at least equal in current or even upgrade to a higher rating. It's an 8amp 500V N FET.

      Is Digikey the best supplier in canada

          yes digikey is the best supplier. The part digikey said would work is 7.1A. Would this be ok?

              Would most likely be fine, sanyo sheet quotes 7.1A @ SANYO’s ideal heat dissipation condition.

              What do you have laying around in the FET department you could scavange?

              Common numbering for these could be 8N50, etc may help find something. generally

                  Actually I have a MOSFET that says T8N50 on it. Would this work? See digikey link below.

                      what's limiting this is most likely the package being full plastic. you could always use standard TO220 with an insulator

                          RJK series Renesas, 50xx or 60xx.

                                  That would do it. Just confirm the pinouts match and you'll need to have an insulator behind the metal tab and an insulator for the bolt

                                  .

                                  When you click on the original link for the Sanyo transistor it shows most people interested in that also interested in AOT8N50

                                      thanks tw2005. Definitely a good idea to insulate otherwise there would be a good spark show lol.

                                          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...

                                          Hellow guys,

                                          I am trying to replace an AON7403 Mosfet but i dot not have in my stock the same. So i wonder if there is any equivalent to this Mosfet.

                                          Thank you very much.

                                          How do you test MOSFET in laptops ?

                                          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                                          ...

                                          Hi,

                                          I'm looking for an equivalent dule mosfet for (IR3598MTRPBF - Dual MOSFET Driver, High Side, and Low Side, 4.0V to 13.2V Drive voltage, 20 ns delay, QFN-16)

                                          it's for motherboard ram voltage.

                                          I hope someone can help me.

                                          Thank you.
