Named 110rki40, this small 63.9 KB PDF is filed under schematics yet the title looks like a power semiconductor part designation, not a device or board. No brand, model, board number or revision is stated, so the name tells little beyond the part code. Treat it as a component reference sheet for checking terminal identification, electrical limits and package drawing during a repair or replacement. Opens in any PDF viewer. Always match the code stamped on the real component with the document first.
