PDF document named after the 2SC5332 part number, filed here under schematics but most likely a component datasheet rather than a board diagram.

A 106 KB PDF for the 2SC3143, which the JIS 2SC designation marks as an NPN bipolar transistor.

Bearing only the JIS part number 2SC2879, this 167 KB PDF is listed as a schematic. A 2SC designation marks an NPN bipolar transistor, so the file most likely contains…

Named after the JIS part number 2SC2816, this 50 KB PDF appears in the schematic category but most likely contains the datasheet of an NPN bipolar transistor, as the 2SC…

A 41.1 KB PDF titled with the part number 2SC1980 and an _E suffix, catalogued among schematics.

Under the Japanese JIS scheme the 2SB726 is a PNP bipolar transistor, so this 39.6 KB PDF, though catalogued as a schematic, should be its datasheet; the _E suffix…

Component datasheet for the 2SB1644, a small 48 KB PDF catalogued under schematics. JIS numbering places any 2SB part among PNP bipolar transistors for low-frequency…

The 2SB1589 PNP transistor is described in this 40.1 KB PDF datasheet, with an _E suffix that most likely points to the English edition.

Datasheet PDF covering the 2SA1588, 215 KB in size, which suggests several pages with curves and package details.
