Datasheet for part 5LP01SP in PDF form, about 28.1 KB, indexed as a schematic. The file name states only the part code; the LP letters appear to denote a P-channel small-signal MOSFET and the SP suffix a package. Technicians reach for this when they need terminal identification, maximum ratings and switching characteristics for a suspect transistor. Before replacing, match the marking on the component and verify the package outline, because several suffix versions share the same electrical die.
