Catalogued under schematics, this 62.1 KB PDF is named 50MT060WH and gives no device, board number or revision. The code looks like a power module or semiconductor part number, so the content is most likely a datasheet rather than a full circuit diagram. Such a document typically shows the internal configuration, terminal layout and maximum ratings. Use it to verify connections and pick an equivalent part, and confirm that the marking on the actual module matches this code before relying on it.
