    MOSFET K18A60V replacement part

    I found a shorted MOSFET in a samsung tv power supply. Its a 600V, 19.5A part. I can't find this part anywhere? Will this part work, or can anyone suggest another part?

    Aliexpress.com has K18A60V. Just over $2 CDN + free shipping.

        Don't put anything else in that power supply. I made the same blunder. I know the power supply is probably a 60 to 64 inch Samsung Plasma right? Two primary MOSFETs on the very left bank right above the input mains? I replace two with equivalent and it work for the first night but the second night they got awfully hot in short it again and then it did more damage to the power supply. I don't know if it was my fault but I would replace the gate driver ic also when you replace those. Just heads up I hate to see what happened to mine happen to yours.

        Did I leave the soldering iron on?

            Hi freakaftr8, are you referring to ICP801? If so, do you know the part number? I can't read the part number on the part.

              Yeah I do I have that spare power supply sitting in my parts bin at home. Ill look at the IC and get back to you tonight

                    Well I looked at that IC tonight and probably just like yours mine is completely unreadable. It has some substance all over it as soon as you rub it off to read the number the number is gone

                      The part number is usually written by laser which leaves a shallow groove. After an IC is cleaned, the number can often be made to show again by applying ink from a white paint pen and lightly wiping it off so the ink stays in the groove.

                        I was able to get the part number by scrubbing it with isopropyl alcohol.

                          It's a Toshiba part, TK18A60V.

                          VDSS = 600V
                          ID = 18A
                          PD = 40W
                          RDSon = 0.19 ohm at VGS = 10V

                            Working on exact same board you guys are talking about. What could be a better fit to replace K18A50D ? I have new Mosfets K18A60V and K15A50D.
