PDF of roughly 41 KB for the component coded 5HP02SP, catalogued as a schematic though the name points to a single semiconductor part. The SP suffix appears to indicate a particular package style within the 5HP02 series. A sheet like this gives the pinout, package dimensions and electrical characteristics needed to verify or replace a small switching device. Before swapping parts, check the package footprint and pin order against the board, because variants of the same series can differ in layout.
