    Diode marked as "E57".........not able to find it by reference
    by Francesc V.
    Hi:

    I have what it might seem a zener diode. It's marked as E57, but I haven't found any reference that might match my observations.

    I've took one from the same circuit and tested isolated with the power supply and a 1k resistor. with 10V, the possible zener stays at 6.6V.

    It seems a SOD123 package. It measures (2.6mm x 1.6 mm).

    Any idea? it's a 6.6V zener?

    Thermistor specs and cross reference
    by connorcc2005
    Hi,

    I'm getting some conflicting information and thought I'd toss it out to all of you for input.
    What I have is a TTC-104 thermistor. This is part of a temp sense circuit that will drive a small 12v fan to cool components mounted to SMPS heat sink.
    The physical diameter of the piece is 5.1mm measured with a caliper.
    Other than what you see in the pic, there is no other writing on the part.

    My research of the TTC-104 says it should read 100 ohms at 25C. Out of circuit measurements have it at approximately 100k. It does change as the temp changes....

    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.

    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...
