    Diode Identification,the marking says "Y4"

    Hello everyone,
    I have diode that needs to be replaced and the marking says "Y4" what does this mean and how do I find a replacement?

    Thank you!

              Shorted TVS diode near power supply connector, I guess?
              When you remove it, hard disk will work without it, still you can replace this diode from other scrap disk on same place...

                  Exactly. Any long term affects without it?

                      In middletime you will not have protection, who saved disk one time already...

                          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...

                          Yamaha delay D1500, zener diode broken with no marking
                          by debidoobs
                          Hello,

                          im actually trying to save a d1500 delay from yamaha. I found the service manual but schematic is missing and BOM list is a bit unclear as components listed have no reference linked to the pcbs... In my case, one zener diode was broken (114 code on the pcb in attached file) and couldn't be repaired : it was a zener type package. In the BOM list i found 3 reference on this board : 1S555 (can be replaced by 1N4148), RD4.7EB2 (approx 5v rectifier), RD7.5EB3 (approx 7v rectifier)...

                          Actually the cathode goes to VCC of sram M5M5118P, without this diode missing, i have...

                          Hello, do you know what it is this component marked RX please ? I can't find it. Probably it is a part of serie, because I saw another marked RW....

                          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....
