I'm trying to resurrect a computer board that was damaged by overvoltage, and I'm having trouble identifying one of the components.
It's a surface-mount chip, six pins, 2mm along its longest side, and the only identifying markings are the letters "KE".
From what I can tell by its position it is power related, either a transformer or a diode of some kind. The board has a 5V supply voltage. All instances of this component I've found are labelled as "DCn".
I've written to the manufacturer asking for a circuit diagram or list of parts, but I haven't heard back. Does anyone on here happen to know what this chip is and where/if I can find a replacement? If it makes any difference, the board is a Diamond Systems AUR-Z530 series.
