    Mosfet Advice

    Hi there - looking for a good mixed bag of mosfets to get started with and keep in my kit - there are several on Ali express - can anyone recommend a good mixed bag from there or anywhere else - I am doing all sorts of electronic repairs at a repair cafe thanks largely to Richard from “Learning Electronics Repair” videos

    Some relevant repairs to date where I’ve needed Fets are DC DC chargers, power supplies, (lots of plug packs) wind turbine controllers,

    thanks in advance

    Mosfet Advice
    by Green Probe
    Hi, Im looking to replace some EMP21N03 mosfets on an Alienware motherboard, but I'm having trouble finding a legit supplier. The ones that are available from China have pictures with the engraved logo looking very scratchy and sketchy. Nobody in the US sells them. I'm trying to find a compatible mosfet, but I'm not well versed enough to be confident im making the right choice. Does anyone have a suggestion or advice that could help me find the right mosfet? Thanks!

    Dell Inspiron 15 7567 (LA-D993P) - No power after replacing blown inductor and shorted mosfet advice needed
    by Reintar
    First of all, I'd like to mention that I'm a novice when it comes to laptop repair, although I do have some experience with soldering.
    One day, my laptop experienced a severe stutter, and after rebooting, it failed to boot into Windows. I decided to disassemble it and found that the PL900 component was blown. Later, I came across a post (https://www.badcaps.net/forum/troubl...error%E2%80%99) with the same problem, where...

    Asus X712EA 3 volts after the first mosfet
    by AppleLover123
    Hey guys,

    i have a asus motherboard here and as the title says after the first mosfet (in the picture) there is nothing more than 3.15v.
    I injected 19v and max. 1 amp at the charging port and there is not voltage drop or smth. It's just taking 19v and 1 milliamp.
    Then i tried to inject 19v and max 1amp after the current sensor and there it first takes 19v and 4 milliamps and after 2 seconds it is taking nothing (no current).
    I measured on the coils on board everything seems fine. Also the main power rail is not shorted (infinite resistance).
    Now i thought something...

    Asus GA502D keeps blowing mosfet
    by Scotchmist
    I have an Asus GA502D, it had a blown mosfet which I replaced and the laptop booted into windows, a few mins later it shut off, the same mosfet was blown. I thought maybe just a bad mosfet but same thing happened again, a few mins in windows and shuts off.

    I have removed the mosfet and can run the laptop no problem

    The MOSFET is FDPC5018SG

    Can anyone point me in the direction of what could be the cause of this, could it be the controller rt3663bc?

    Thanks

    MOSFET? Is its voltage reading normal?
    by alro7779
    Hello, guys!
    Got this 8-pin MOSFET (I presume) on the motherboard that I'm still trying to repair (HP Stream 11-ah117wm DAY0HGMB6C1 REV:C), close to the DC IN connector, and when I read voltage on Drain (5-8 pins) and Source (1-3 pins), I got the 19.81 VDC of the DC IN on each, but on the Gate (pin 4) it's 25 VDC. Is it normal? Now, I'm not quite sure the component is a MOSFET, but it looks like, and since it has the printed code on it totally unreadable, I can't try to find the datasheet. Can anyone give me a hand on this? Or maybe ff there's some MOSFET tutorial or something that you can...
