Indexed as a schematic, the 104mtkb document is a 159 KB PDF whose name follows a power semiconductor series style with no voltage suffix, device model, board number or revision stated. The lack of a grade code suggests it may cover a whole series, though the name alone cannot confirm this. Use it to look up terminal layout, ratings and mechanical dimensions when testing or replacing such a part. Opens in any standard PDF viewer; compare the full code on the component with the sheet first.
