    LG50 pc1-Does anyone recognise this diode?

    LG50 PC1

    I've got an open circuit diode on psu board , but I can't find a replacement with the number thats on the diode.

    Board. J012B

    Location D601

    marking; As on the diode
    3PDA
    60
    6D

    black with silver banding on one end.
    size 11mm long 5 mm dia

    Any help would be appreciated.

    A picture showing the location might be instructive. I'm recalling a situation where someone had a similar question; the diode was across the AC input and was for transient protection. It didn't start to conduct until the voltage across it exceeded 400 volts.

    For a number of reasons, both health and personal, I will no longer be active on this board. Any PMs asking for assistance will be ignored.

    Never be afraid to try something new. Remember, amateurs built the ark. Professionals built the Titanic.

      Based on the markings and information I have found, I would say it is 600V 6A.

        Many thanks for both of your replies. I've attached pictures showing location as requested.

        Help me to understand electronics a bit better. How did you come to the conclusion its a 600v 6a?
        D601 location is adjacent to 2 large caps.
        In one of the photos I've removed bank of fets to try and make location clearer.






        I appreciate your help in trying to sort this one.

          Looks like a 2A or 3A Schottky or silicon diode. A 600V 3A Schottky would probably work.

            Thanks for your advice. I see if I can but one.

            Just out of interest. I've got an identical working set. Are there any live tests I can do to confirm that the sustitute diode will be up to spec?

              It's tricky... You could try an RMS ammeter in series with the diode but that would probably prevent proper operation of the TV due to the voltage drop across the ammeter. The two diodes should be approximately the same size both in case diameter and length, but bigger is not an issue.
