    Diode GO C 40

    Hi

    I need to replace a defective diode in a power supply. the diode's code is GOC 30 or GOC 40.

    I haven't found any details about this diode, anyone can help me on this? the code is first line GO or G0, second line C third line 40

    Thanks for your help

      Which diode, in which housing, post a photo of it.

              are there more?
              if you can check the voltdrop and it's under 200mV then it's probably a schottky rectifier

                  What Zener Diodes on a Linear Power Supply
                  by caspian
                  Dear members,

                  I have a linear variable power supply with unknown brand name that I used for voltage injection.
                  Then it failed. I discovered that its transistors (Q1 and Q2) are shorted.
                  In addition, I discovered that its zener diodes are defective.
                  I can replace the burned transistors.
                  But I do not know the model of the zener diodes. the model number is not marked on the zener diodes.
                  Therefore, I cannot replace the zener diodes.
                  I do not want to test the zener diodes in a test circuit to discover their model or value.
                  no schematics are available...

                  Hi everybody.
                  I'm trying to fix this toothbrush that doesn't wanna start. And I need your help.

                  Just to inform you that I'm supperbeginner

                  First photos are from internet because I did not took a photo of whole board.

                  I have noticed that fuse marked with "E" near the battery pole is bad and decided to short it with a "proper calibrated wire" as one would say.
                  Now, when I apply 1V from the power supply, limited to 500mA, one of the component stick out from the rosin mist. CHC N2AB (or some variation of that letters) is the hottest...

                  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....

                  Behringer Eurolive B205D repair - help identifying transistor
                  by magneh
                  Hello
                  Got this speaker from a friend , defective. Power led comes on and off , in a loop.
                  Disassembled, got the board out, and after a bit of measuring I found a low resistance on a 5v6 line. With a bit of current I found a transistor heating up on that line (labeled T1 and 113 as on pic).
                  After removing this guy, I got a value of 0.7 in diode mode on that 5v6 line, which before had 0.02 or something like that.

                  I tested powering it up without the IC, and the speaker turns on and stays on, and works fine

                  Still, I need to replace this transistor....

                  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.
