Datasheet in PDF form for the 2SA1562 transistor, 95.5 KB. The name gives no equipment, board or manufacturer information.

Part number 2SA1533 names this 51.3 KB PDF, with an unexplained _E suffix; despite the schematic category it is presumably the transistor datasheet.

At 95.1 KB this is one of the larger files in the set, a PDF named after the 2SB1205 transistor and indexed as a schematic, though it is presumably the datasheet.

Named after the 2SA1527 transistor, this 30.7 KB PDF appears in the schematic category though its content should be the datasheet for the part.

Datasheet-style PDF for the 2SA1523 transistor, catalogued as a schematic but named after a single part number.

Combined PDF, 53.0 KB, whose name lists two part numbers, 2SB1189 and 2SB1238, suggesting one data sheet covering both transistors. It is filed as a schematic.

Reference sheet for the 2SB1184, a part number in the Japanese JIS series where 2SB indicates a low-frequency PNP bipolar transistor.

The 2SA1438 transistor is described in this 133 KB PDF, which the index files under schematics.

Compact 41.4 KB PDF for the 2SB987, with an _E suffix not explained by the name, perhaps an edition or language marker.

PDF documentation, 75.9 KB, for the 2SA1434 transistor. Under the JIS scheme the 2SA prefix denotes a PNP transistor, and no other variant, maker or package information…

PDF reference of 182 KB for the 2SA1431 semiconductor. Following JIS rules, 2SA part numbers are PNP transistors, formally classed for high-frequency use.

PDF reference for the 2SA1360 transistor, roughly 176 KB. The file is labelled a schematic, but naming it after one part points strongly to a datasheet.

PDF datasheet of about 201 KB for the 2SA562TM transistor, where TM is a variant or package designation attached to the 2SA562 base number.

Transistor datasheet for the 2SA2070 in PDF format, roughly 189 KB. The 2SA prefix places it in the JIS category of PNP transistors for high-frequency use.

For the transistor 2SA2039 this 40.2 KB PDF most likely provides the manufacturer datasheet, even though it sits in the schematic category.

Datasheet-style PDF, 229 KB, for the 2SA1293 transistor, indexed here among schematics. Only the part code appears in the name.

Brief 13.0 KB PDF datasheet for the 2SA1012 from UTC, that is Unisonic Technologies, which manufactures this transistor number among others.
