    Identifiing mosfet component - Replace with?

    Hi all,

    Hope, this is the right place to ask.
    I'm trying to repair a battery charger and the mosfet in the picture is shorted.
    Can't find a datasheet, but it seems I can replace it with MJE13003.

    Thanks in advance,

      See this thread:

      https://www.diyaudio.com/community/t....258020/page-6

      There is a transistor with exactly the same markings, but in a TO-92 package:

      The date on the PCB is 2012.01.13, so this would suggest that "08" may not be a date code.

      FWIW, MJ13003 also comes in many different packages:

          MJE13003 appears to be phasing out or obsolete but Mouser.com still stocks KSE13003H2ASTU which appears to be a direct replacement. Good luck!

              I'll try the MJ13003 and post the results here.
              Thanks for your time

                  Just about any manufacturer that makes *13003 NPN BJTs should do. 13003, 13005, 13007, 13009 are all standard parts, so shouldn't matter which manufacturer you get it from.
                  Whatever you do, just avoid the cheap China knock-offs on China mall stores on Amazon, AliExpress, eBay, and etc.

                      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                      ...

                      330S-15IKB Components to replace along with shorted power MOSFET
                      by Shuasmith14
                      Hello. I'm currently working on a Lenovo Ideapad 330S-15IKB that has no power, no power light, dead. I found the schematics and I'm seeing proper voltage at the drain of the first DC IN MOSFET and nothing after. After doing some research and finding the power supply troubleshooting guide in this forum. I tested the second DC IN MOSFET and it's shorted from drain to source. My main question is since I'm new to doing this, I thought I heard somewhere that any time a MOSFET goes, you're supposed to replace the controller as well. That may not be right but I want to check if there's anything else...

                      Lenovo Y700-17ISK mosfet to replace
                      by madjid911
                      HI, I have a Lenovo Y700-17ISK laptop (motherboard BY511 NM-A541) which does not start anymore.

                      I found the fault, it is a power input mosfet 6414A which is in continuity, it is part of the two fuses powered by the BQ24 manager.


                      I found a PKCH2BB mosfet in stock to replace it. is it not dangerous to put one with much more amperage for this use?

                      6414A N-CHANNEL 30V 30A
                      PKCH2BB N-CHANNEL 30V 228A

                      I am not an expert, your help is precious, thank you....
