A 41.4 KB PDF covering the 5HP02C part, indexed under schematics. Only the component code is present in the name, with C most likely denoting the package type. Such a document normally lists terminal assignment, absolute maximum ratings, electrical characteristics and a mechanical drawing. It is useful when a burnt or shorted small transistor must be identified and replaced with an equivalent of matching polarity and voltage. Check that the footprint on the PCB matches the drawing before fitting a substitute.
