Datasheet-style PDF for the 5LP02SP, about 42.2 KB and placed in the schematic category. The file name gives only the part code; in this numbering family the LP letters seem to indicate a P-channel small-signal MOSFET, with the SP suffix probably naming the package. A technician would check the gate, drain and source pin layout, the threshold voltage and the current limits here. Confirm the package marking on the PCB before relying on it, because sister parts differ mainly by case style.
