Datasheet-type PDF of 43.3 KB for the 2SC5335, with an _E suffix that may denote an English version, though the name does not state it.

Compact 102 KB PDF for the 2SC3090 transistor, indexed under schematics. The name carries no detail beyond the part code.

Named for the 2SC2995, this 510 KB PDF is listed as a schematic but most likely holds the datasheet for a JIS-numbered NPN transistor, as the 2SC prefix indicates.

Indexed under schematics, this 223 KB PDF takes its name from the JIS part number 2SC2960, an NPN bipolar transistor designation.

Filed under schematics, this 80.8 KB PDF is titled with the part number 2SC2857. The JIS 2SC prefix designates an NPN bipolar transistor, so the content is most likely a…

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…

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.

Small PDF document for the 2SB1537, a Japanese JIS-registered transistor part number, catalogued here as a schematic although a part code like this normally points to a…

An 89.5 KB PDF describing the 2SB1396, a JIS-registered part; the file name gives no further specifics.

Reference sheet in PDF form for the 2SA1593 transistor, 156 KB in size. The name gives only the part number, with no device or board details.

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

Catalogued as a schematic, this 40.7 KB PDF is named after the 2SA1540, a Japanese JIS-registered transistor part number, so it is most likely the component datasheet.

A 41.5 KB PDF for the 2SB970 transistor, with an _E suffix the file name leaves unexplained.

PDF for the 2SA1254, 43.0 KB, whose name ends in an E suffix that may denote a language or edition variant, though the file does not confirm that.

PDF document for the 2SA1246 semiconductor, filed under schematics but named only by the part number, so it is most likely the component datasheet.

A 28.6 KB PDF named after the 2SA1179, a PNP transistor under the JIS 2SA designation. With only a part number in the name, it is almost certainly a brief datasheet…

The 2SA1865 PNP transistor is described in this 55.3 KB PDF, identified solely by its JIS part number.

Short PDF of 47.9 KB named 2PC945 with suffix 3, which likely marks the data sheet revision.

2N5400 transistor datasheet marked Sam, a 56.9 KB PDF that probably originates from Samsung, although the name alone cannot prove it.

PDF datasheet of 52.2 KB for the 2N2369 NPN switching transistor, placed in the schematic section.
