Datasheet-style PDF for the 3LP02N, about 41.5 KB and listed as a schematic. No device, brand or board details appear in the name beyond the part code itself. Related entries 3LP02M and 3LP02SP suggest the trailing letters separate package versions of one base transistor. The document is useful for confirming pinout, voltage and current limits and the package drawing during repair. Any PDF viewer will open it; match the SMD code and case style on the PCB before ordering or soldering a substitute.
