    Default Insulation needed?

    Wow, I go away for a week and all these 445nm diodes pop up for insanely low prices! Not surprisingly, I have scraped up some funds and have put my foot in the door, for my scanner

    I believe these diodes are case neutral? Do you recommend they be insulated from the baseplate? I don't intend on TEC cooling my module, as my baseplate should be enough thermal mass to keep it happy, but I haven't seen any talk on whether they need to be insulated or not.

    Cheers,
    Dan

    both anode and cathode are isolated from the diodes case...

    Ah, that makes things easy then

    What I did is hook the diode up to the driver, and tie the case to a solid equipment chassis ground.

    I talked about this in a different thread, but I've found that connecting the case pin to the cathode on floating-case diodes helps make them much less susceptible to ESD.
