    Thru Hole Diode markings

    Hi guys, I need to identify some diodes that I need to get the part numbers for. They are very small and have numbers on them. See pic below. Is there a marking code book for these parts. I'm pretty sure they are zeners, but I need a part number.

        I wonder if that is one of those gas fuses?

          Can we see the board and the location of these devices?

            by petehall347
            smd package .measures roughly 4x2 mm so thinking its DO-214AC markings are SA then under it is 39 .i believe 39 to be the date code .

            Burnt Hole under IC on MacBook Pro M1 Pro 14"
            by silberdrache
            Hello,
            I'm new to this Forum, so I hope it's the right place for this topic.
            Im a student from germany, and as a hobby I repair electronics. I started microsoldering maybe 1-2 years ago.
            I have a MacBook Pro 14" m1 Pro with 10 Cores and 16/1tb storage. The board Number is 820-02098-A.
            The MacBook has a light water damage. Coffee got spilled over it, but the Mac continued working only the battery didn't charge anymore and when the battery was empty the Mac turned off and doesn't show any sign of life now.
            I opened it up and there were only three drops of coffee...

            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.

            Bose Acoustimass 10 IV Subwoofer No Sound. Help with burnt component identification?
            by nobbnobb1
            I picked up this used Bose Acoustimass 10 IV speaker system. Speakers seem to work fine, but the subwoofer does not make any noise. So I took apart the unit and found some obviously failed (burnt) components:

            - 1x 3.14 A @ 250V main circuit fuse
            - 1x bridge rectifier GBU601. there's actually two of these on the board, one is obviously burnt and the other does not seem to have any anomalies like shorts. However I figure may as well replace both.
            - 2x diode. This is tricky because the only markings I see on it are: "617 402". No current rating or anything else....
