Compact 27 KB PDF named 5HP01M, catalogued as a schematic but pointing to a single semiconductor component. The M suffix likely distinguishes one package from its siblings in the same series. Look here for pinout, absolute maximum ratings and mechanical outline. When a small part on a board is shorted or missing, this sheet helps confirm its function and select a substitute with matching polarity and ratings. Verify the board marking and package size against the drawing before relying on it.
