PDF reference for the 2SC3665, sized 175 KB, with no device or board information in the name.

The file name gives nothing beyond 2SC3460, a Japanese JIS designation in which the 2SC prefix denotes an NPN bipolar transistor.

Just under 100 KB, this PDF is identified only as 2SC3448 and catalogued as a schematic.

Transistor data in a 215 KB PDF named 2SC3376, catalogued as a schematic. The 2SC prefix belongs to the Japanese JIS scheme and marks an NPN device intended for…

A 320 KB PDF named for the 2SC3329, listed under schematics though it is most probably a full transistor datasheet.

The 330 KB PDF here carries the part number 2SC2551, a JIS-registered NPN transistor designation.

At 160 KB, this PDF for the 2SB1667 is larger than the other 2SB166x and 167x sheets, perhaps containing more curves or pages.

English-language edition, judging by the _E suffix, of a document for the 2SB1488 transistor, stored as a 46 KB PDF under schematics but almost certainly a datasheet.

Information sheet for the 2SA1669 transistor in a 130 KB PDF. No additional specifics appear in the file name.

PDF file of 231 KB for the 2SA1586, catalogued as a schematic but named after one discrete semiconductor.

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.

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.

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.

For anyone replacing a 2SA1417, this 141 KB PDF gives the component reference in one document, though the index labels it a schematic.

Compact 88.2 KB PDF for the 2SA1348, labelled a schematic but most likely a datasheet, given that the name contains nothing beyond the part 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.

Specifications for the 2SA1963 transistor are expected in this 160 KB PDF, which the index labels a schematic.

PDF documentation, 260 KB, for the 2SA1955 transistor, listed under schematics but most likely a datasheet because the name is only a part number.

Datasheet-type PDF for the 2SA1939, roughly 170 KB, catalogued here as a schematic. The filename names only the component; the JIS 2SA prefix marks it as a PNP bipolar…

A 137 KB PDF on the 2SA1225, named only with the part number; despite the schematic category it is most likely the manufacturer datasheet.

Datasheet PDF, 40.9 KB, for the 2SA1128 transistor, with an _E suffix that often denotes an English edition of Japanese documentation, though the name does not confirm…
