    Name this Zener

    Hey Guys,
    I am having a little trouble identifying this Zener diode on an NEC DTL 12D telephone main board. Any help would be greatly appreciated.

    Dimensions are 1.25mm x 1.70mm

      Is it bad? Can you find another one on the board so you can do the Voltage test?
      BTW, can we see the whole board to see how it is hook up in the circuit so we can figure out if it is Zener diode or not?
      8.2V?

              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.

              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...

              What zener diode might fix the sound on Maestro Mayhem gaming chair?
              by nev1001
              Hi, I'm looking for a bit of help trying to fix the audio unit from a Maestro Mayhem 4.1 gaming chair please.

              The chair has a few speakers and vibration motors. All was well, for a while, but now the sound is gone.

              It may be significant that I discovered my son was powering it with a 19V laptop charger when it should run on 12V - it did fully work, for bit.

              I think an issue could be a zener diode (or capacitor) which has shorted out.

              The board's bluetooth input still works, the vibration motors are working, so is the line out socket but not the...

              Element 32 inches tv (ELEFW328B) Unknown component: Diode or zener?
              by Vincenzo2
              My Element 32 inches tv (ELEFW328B) lost it's backlight (confirmed with a flashlight test) and the connector on the PCB (it has one board that has a processor chip, switch mode power supply, and backlight circuit) that has the two wires that go to the backlight LED strips has a very low voltage (28-29 volts) when turned ON, in my opinion.

              Started testing components and found an SMD diode or zener that is shorted (even zero fusing resistors read a few tens of milliohms, while this thing reads zero).

              I put some pictures here to show that it is labeled "M7"....

              Corsair RM1000e - Help identify 5VSB Zener diode
              by hobostove
              Hey there guys. I've got a Corsair power supply that's come across my bench dead. I usually don't mess with power supplies, but it's a slow week so I'm giving it a whirl.

              Taking it apart I heard a screw rattling around inside, and when I got it apart I found a couple blown components near what I think is the 5VSB area.

              There's a 22ohm resistor that's melted and open, but it still has the bands.

              The other part is a zener diode and it's top went to jesus, so I can't read the marking.

              It looks like the diode connects the source and drain of a TNY284...
