    Ar300 psu

    Hiya folks... i'm just about done rebuilding an AR300 but need to double check the correct orientation of the zener diode. can anyone tell me if the bent leg is the anode or cathode, or the black ring in the diode would it be at the top or the bottom in Sylvester's photo. ?? i don't want to do all that work and have it fail cuz the diode is back to front.... the one i took out was too badly damaged to tell.

          For the record, since I'm looking at one of these supplies now, I can state that the Anode (non-stripe) end is (fully) inserted in the hole closest to the IC. But this is also indicated on the silkscreening, which has the symbol with anode end close to IC.

              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...

              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...

              NTE Electronics “NTE5251K” Zener Diode 9.1V @ 50W Do-5.5% Want to build a 9.1 output from a 9.6 lipo4 battery pack
              by sam_sam_sam
              I have bought this Zener Diode for this project what size and wattage resistor value do I need to use to get near 50 watt output
              I bought this from an eBay seller but unfortunately they only had one

              I bought three from Vetco Electronics these are Sylvania ECG5185A 9.1@10w A to Stud what size and watt resistor do I need to use to get near 10 watt output
              I bought three of from them to also make battery packs with this output power limit in mind

              I want to use this battery pack and turn it into a 9.1 output battery pack output to eliminate using 9 volt battery...
