Reference sheet for the 2SC2792, supplied as a 186 KB PDF and listed in the schematic category, although the name points to a component datasheet.

The 2SA1539 part number gives this 41.0 KB PDF its name, and although it is filed under schematics it almost certainly holds the datasheet for that transistor.

Part number 2SB1209 with an _E suffix identifies this 42.6 KB PDF, filed under schematics though a single-part document of this kind is normally a datasheet.

A 130 KB PDF named for the 2SB1188, indexed as a schematic but by its name a single-transistor data sheet.

At 262 KB this is the largest file in the batch, a PDF for the 2SA1432 transistor, likely holding graphs and package drawings as well as the rating tables.

The 2SB906 transistor is the subject of this 196 KB PDF. Following JIS designation, 2SB parts are PNP bipolar transistors classed for low-frequency use.

The name 2SA2025 on this 38.7 KB PDF is a JIS transistor number; the 2SA prefix means a PNP bipolar device.

PDF reference for the 2SA1203, 99.3 KB, sorted among schematics although the bare part-number name points to a datasheet.
