Datasheet PDF of 42.2 KB for the 2SA1883, identified only by its part number. Japanese JIS numbering uses 2SA for PNP bipolar transistors, so the content describes a…

Specifications for the 2SA1873 PNP transistor, provided as a 247 KB PDF. The 2SA prefix comes from the JIS semiconductor naming system and denotes a PNP bipolar part, so…

Component sheet for the 2SA1866 PNP bipolar transistor, stored as a 55.4 KB PDF. The 2SA prefix follows Japanese JIS conventions for PNP devices.

Specification document for the 2SA1728, provided as a 91.2 KB PDF with no board or device model in its name.

A 64 KB PDF covering the 2N7218, indexed as a schematic though the file name is a plain JEDEC part number and the content is most likely a single-device datasheet.

A compact 43.5 KB PDF filed under schematics and named for the 2N6547, a part number from the JEDEC 2N registration series for discrete semiconductors.

PDF reference sheet, 214 KB, for the 2N6282 discrete device, listed as a schematic but most likely a datasheet.

A 90.8 KB PDF titled only with the part number 2N5550, so no board, laptop model or revision can be matched.

Datasheet-style PDF of 166 KB for the 2N4125, with an RE suffix appended to the part number; the name does not explain it, so treat it as a possible alternate or revised…

Datasheet for the 2N2222A transistor, a 53.4 KB PDF whose name carries a Phi tag, most likely identifying the manufacturer edition.
