Small PDF of 26.5 KB named 5HP01SS, listed as a schematic yet evidently referring to a single semiconductor part rather than a board. The SS ending is presumably the smallest package option in the 5HP01 family. Read it for pin order, ratings and outline, which matter when diagnosing a failed switch device under a microscope or searching for a compatible replacement. Tiny packages are easy to mount rotated, so confirm pin one orientation on the drawing first.
