    2SK3563 Mosfet replacement

    I need to replace one in the Philips 32pfl3504d/f7 TV PSU
    Digikey has no stock
    What are the most important parameters that should match?
    Please help me finding a suitable replacement.
    Will TK10A50D work?

    The schematic is attached (Q601 on page 5)

    Located in US so shipping should be fast.....
    I only repair Panasonic plasma tv's! Currently owning a TX-P55VT50 and still searching for a ZT60!

        My concern is the switching time, which is 2-3 times slower.
        Rise time is 25 vs 10 ns
        Turn-on time is 60 vs 20 ns

        But I'm not sure how important is this characteristic in this case of SMPS use.

          looking at this one on digikey: IPA65R1K0CEXKSA1-ND
          seem to be better overall and one of the cheapest available (<$1)

              Just an update: the replacement IPA65R1K0CEXKSA1-ND worked just fine. Fixed the Philips TV.
              There are many other siblings with slightly different voltages, I believe they would also work just fine.
              Also replaced driving transistor 2SC2120 with BC33725TACT-ND (BEWARE THE PINS ARE DIFFERENT - BEND THE LEGS)

                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!...

                Hp Lh482p 5 short 3 long short after cpu vcore mosfet replacement
                by jm942
                Hi,
                My laptop went dead and after checking ,the main 19 volt power rail was shorted. After some checks i could identify that a high side vcore mosfet was shorted.
                I replaced the mosfet and now the white powerled is present , fans start spinning but capslock shows the famous 5 long and 3 short code.

                I checked the vcore voltages after replacement and i get for all 1.01 V so means for me that the driver is still working of the replaced shorted mosfet. On the Nvidia i measure around 0.8 V after the mosfets.
                I did voltage injection on the cpu with 0.7V and i have a current...

                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
                ...
