    Re: Diode "ZL9528" where can I find some

    When you can't find it, it helps to give us context.

    1) A picture helps.
    2) Where is it in the circuit board?
    3) What is the piece of equipment?
    4) Is there a schematic available?

    If you are new to this forum, we can help a lot more if you please post clear focused pictures (max resolution 2000x2000 and 2MB) of your boards using the manage attachments button so they are hosted here. Information and picture clarity compositions should look like this post.

    We respectfully ask that you make some time and effort to read some of the guides available for basic troubleshooting. After you have read through them, then ask clarification questions or report your findings.

    Please do not post inline and offsite as they slow down the loading of pages.

        Depending on the age of the product, "9528" could be a datecode - 28th week of 1995.

          Thank for the info

          I will have to remove them from the board and see if there are any other # on it

            Hm, this seems more like a marking number for the part on the board, (I.E. "C1", or "R3") rather than the ID of the actual part. What package is it in? (D0-201, D0-41, etc..)

              sam, a 2N6403 is an SCR, suggesting that what you are working on is mature technology, if not also some 15 or 20 years old. Industrial equipment is often expected to have a life measured in decades, so I'm not being critical. One hint as to the age of what you are working on (and to whether "9528" might a datecode) is whether the 2N6403 was made by Motorola or On Semiconductor (which was spun off from Mot in 1999). You may also find datecodes ("YYWW" or "WWYY" are common formats) on the PCB, electrolytic caps, ICs or large discrete semiconductors (e.g. TO-3, TO-220, and TO-3P or TO-247 packages). Some equipment even includes a date code in the serial number (e.g. Transistor Devices electronic loads).

              Speaking of packages, is the device in question in a large high current package? Or a low current package. If it's the former, the 16A, 400V current and voltage ratings may be a clue to suitable equivalent parts. Also, SCRs are not fast switching, like MOSFETs. So a >/= 16A, 400V fast recovery (100-200nS recovery time, not a 20-50nS ultra-fast type) rectifier in the same package and pin-out might work.
