    Help to identify SMD Zener diode

    Hi, I have this Zener diode that is open.
    I took pictures before desoldering it, I have attached them here.
    Can anyone tell what Zener voltage this has from the markings?
    I have an idea but don't want to cloud the opinions so I'll wait for what you say...

    5v1 zener or a 7v tvs in my book.

      Not sure if SOD-123 or SOD-323 package.
      Diodes Inc DDZ5V1BS SOD-323
      Diodes Inc DDZ5V1B SOD-123
      It used to be a Zetex part.

        probably get an educated guess from where it is fitted in the circuit . tvs would test open as a diode . is there another the same in the unit ?

          Thanks, yes this is the same as I figured, it seems to match SOD-123 physically and that it infact is a Diodes Inc DDZ5V1B (5.1v Zenerdiode with 0.5w rating)
          What threw me off was a Youtube video where in the comments people wrote it was a 5.2v Zener, but seeing how uncommon those are I doubted it...
          I'm glad you all agree

            Posting this here also for future reference, it's from the datasheet.
            The date code marking is B5 (May 2014) and this matches well with other components on the PCB.
            The zener diode model marking is KM (DDZ5V1B)
