Part reference sheet for 5HN01C, a compact 26 KB PDF listed under schematics. No laptop model or board number appears in the name. The code resembles small-signal transistor numbering, and the trailing C most likely marks a package variant. Expect pin assignment, absolute maximum ratings and typical curves rather than a circuit diagram. It helps when identifying a failed SMD part found on a board, or when checking that a substitute matches in pinout and voltage rating. Open it in any PDF viewer.
