    Help identify Diodes

    Could someone help me identify marked Diodes?
    They are on input of POE lines at Cisco AP.
    Both are OL in both direction.

    Thank you!

      They look like bi-directional Tranzorb TVS diodes (no stripe) by Vishay; diode markings. NM date code 38?

      It's normal for them to read open in both directions until their clamping voltage.

          On M-Audio AV40 active studio speaker's two zener diodes get really hot.
          by Dvsr
          Hi. I need help from wiser guys. I am amateur in electronics and can't figure this out by myself.
          I bought faulty speakers, M-Audio AV40's. Other speaker has all the electronics in it and the other speaker is just passive one powered by the other speaker's amp. Original problem with the speakers was loud buzzing. I figured out that there is something wrong with the capacitors. I went ahead and replaced every electrolytic capacitor on the PCB. The caps are good quality and have the same values as the original ones.
          After replacing the caps I started testing out the speaker. It seemed...

          What Zener Diodes on a Linear Power Supply
          by caspian
          Dear members,

          I have a linear variable power supply with unknown brand name that I used for voltage injection.
          Then it failed. I discovered that its transistors (Q1 and Q2) are shorted.
          In addition, I discovered that its zener diodes are defective.
          I can replace the burned transistors.
          But I do not know the model of the zener diodes. the model number is not marked on the zener diodes.
          Therefore, I cannot replace the zener diodes.
          I do not want to test the zener diodes in a test circuit to discover their model or value.
          no schematics are available...

          Motorbike PCB - burned Diodes ( PJ78) - help to identify identical or equivalent
          by magneh
          Hello everyone

          Got a motorbike PCB that had 3 burned diodes.

          The smaller ones have the marking PJ78 GS1M
          And one larger one PJ78 GEX

          Can someone help me identify them so I can be able to replace with same or equivalent?

          Apreciate !
          Thank you...

          DVR HIKVISION DS-7208HWI-E1/A BOARD DS-80104 REV 2.2 help identify burnt components
          by thesame
          Hy guys , i have a DVR board DS-80104 REV 2.2 that was powered wrong, i have some smds on the board that are blown and i can't identify them , maybe if someone has this board somehow and we can identify the smds', i have searched online and i can't find a schematic.
          The smds are SOT-23-6 , one of them i think it has the marking ADJF since i found another one on the board with this marking , but the other one it seems that it starts with AG or it looks like. I would really apreciate if someone could help me identify those IC's .

          Lenovo Legion 7 - Help Identify IC
          by silver60618
          Hi gang, its a long shot, but working on Lenovo Legion Pro 7 motherboard NM-F091, and trying to identify this component near GPU with marking "eHFQH" that is burned and shorting the board. Looks like power management IC

          I couldnt find any schematic or boardview. The CPU side also has same chip. Any way to identify this chip? or take measurements from the good chip to determine what it is?

          Any help would be appreciated...
