    optocoupler? B3PBE0000060

    Hi,
    I'm troubleshooting SN board of Panasonic plasma TV and I'm curious about a component that looks like an optocoupler, it has 5 legs though. I tried to check between legs 1-2, but no diode junction there, it's open. So either that is not a diode there or it's burnt.
    For future searches, the part num is B3PBE0000060, the label on the component says 9157 and N219.
    Any idea?

          Thanks, but I don't see any data sheet for either 9157 or PS9157.

              I dont know, maybe try similar ps9151pdf and extract/conclude needed data.

                  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...

                  by eccerr0r
                  I was looking at an old battery powered electric lawnmower I picked up as the previous owner didn't want to buy a new board to replace a ruined old board. Tried to study how it was designed - it appears it has a huge 80A contactor...or rather, a 80A relay. It appears to be SPDT to control the motor. A 30A relay protects the circuitry.

                  The weird thing I don't quite get is how this thing is connected. The common contact is connected to the motor. The NO contact is connected to the battery, which is expected, so when the relay is activated, the common is connected to the NO contact and...
