    LV49 SMD diode

    Could someone help me identify this diode? LV 49 from Taiwan semiconductor.
    Some fets blew up on my Robitronic RC speed controller and this thing popped as well.
    I've looked in Taiwan semiconductor's part datasheets, but it's not listed.

    Finding replacement diode iPad Pro 3rd gen A1701
    by asr
    Hello, I am looking for help to replace a damaged diode. The tristar was replaced and a diode was damaged in the process. I have a picture of the diode but dont have an exact donor. I mostly have macbooks for donors and only a few ipad and iphone boards. Diode part number: DSF01S30SCAP
    Im not sure where to find the ipad board number. Anybody have an idea where else this diode is used on other boards? Thanks....

    TV backlight zener diode
    by unimatrix93
    Hello everyone, I'm repairing an LG TV backlight and I noticed some strange behavior when I touching the backlight strip with a missing Zener diode.

    So I replaced the leds on the strips and they seemingly working fine, but soon as I touch the strip which has a missing Zener diode the whole backlight turns off for a few seconds and then turns back on.

    Is this caused by the missing diode? If so what kind of zener diode should I use to replace it?.
    ​​​​
    The led strips has 9 6V leds.

    MBR3045CT and SR3045LCT Schottky diode testing help.
    by Baste
    Hello experts,
    Can anyone educate me on how to test MBR3045CT and SR3045LCT Schottky diodes? I'm totally a newbie in electronics, so forgive me if I have cheap tools. In my effort to repair a Gigabyte PSU, I stumbled upon the two diodes, which I suspect are leaky. I tested this with my two cheap multimeters and the newly bought LCR-T4 MC328, and I got confusing results. Below are my test results.

    Aneng ST182 Meter.

    MBR3045CT:
    Diode mode
    Pin 2-1 - 0.150v
    Pin 2-3 - 0.150v ...

    monowheel repair,Is the diode the problem?
    by NicRac
    Hello everybody☺️ I am glad to be here and looking forward to a good discussion.

    First of all, I am new here. Therefore I will shortly introduce myself.
    I am Nico and currently I study Physics.
    In my freetime I like to build and repair stuff. Especially big battery's.

    A few years ago I got myself an electric unicycle, monowheel or however you call that.
    The battery bms was broken so I replaced and resolder that. Nothing big.
    I used this thing for some years and had a lot of fun. Unfortunately I used it last time in heavy rain. Usually everything...

    NO BODY MARKING Diode
    by dennis_elx33
    Hello Everyone,
    I have 1 diode on a circuit that I suspected to be faulty because the forward and reverse bias has a voltage drop reading.
    While compared to the reading of another diode from the next channel it won't read at reverse bias.
    Now the problem is; it does not have any body marking.
    So I tried to sketch the diagram and found out that it is connected to the base and collector of the C3632 transistor.
    What do you think is this diode?
    Can you please suggest what part number can i use to replace this faulty diode instead?

    Hoping that you...
