    mtz30 zener diode substitute

    hi there
    im working on a power supply for a plasma tv ,i have located the fault a bad zener diode ,according to the schematic it is a mtz30 but i cant seem to find that exact part ,is there a suitable replacement i could use instead, preferably from uk supplier.
    thank you.

      This one should work for you. http://ca.mouser.com/ProductDetail/N...EnSri0l7uMU%3d . I've not run into a MTZ series before but the sheet looks like this one will work. Don't know where you would get one from.

          it's just a 500mw 30v zener diode,
          any zener that's 30v and atleast 500mw will do.
          i'd fit a 1.3w because i like to go up with the ratings.

              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...

              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...

              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...
