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.

A small PDF of 40.7 KB for the 2SA1538, a JIS-coded transistor; despite the schematic label, a file named only by part number is normally a datasheet.

This 41.1 KB PDF bears the part number 2SA1536 and, although indexed as a schematic, is best treated as the datasheet for a JIS-registered 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.

Reference sheet for the 2SA1519 PNP transistor in PDF form, about 30.2 KB, categorised here as a schematic.

Data reference for the 2SA1507 in a 53.1 KB PDF, categorised as a schematic. The 2SA prefix, per the Japanese JIS system, indicates a PNP transistor.

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.

PDF file of 177 KB dedicated to the 2SA1426, a part whose 2SA prefix denotes a PNP transistor under the Japanese JIS system. The name states only the part number.

Datasheet-style PDF, 201 KB, for the 2SB908 transistor. Japanese JIS numbering uses 2SB for PNP transistors intended for low-frequency service, which commonly means…

Datasheet PDF, 24.1 KB, for the 2SB772L variant from UTC, likely Unisonic Technologies.

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

The 2SA1259 PNP transistor is the subject of this 43.4 KB PDF, which the index files as a schematic.

PDF, 117 KB, for the 2SA1926 component. Although filed under schematics, the name contains only the part number, so the content is most likely a datasheet.

Part reference for the 2SA1208 as a 44.3 KB PDF, placed in the schematic category though nothing in the name goes beyond the component number; expect datasheet content.

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

A compact 31.6 KB PDF covering the 2SA1857, listed under schematics but most likely a component datasheet.

The 2SA1813 is covered by this 83.4 KB PDF datasheet, a PNP bipolar transistor according to the 2SA prefix of the Japanese JIS scheme.

Component datasheet for the 2SA1803, provided as a 179 KB PDF and indexed with schematics. The 2SA prefix places it among PNP bipolar transistors under the JIS standard.

Small 39.2 KB PDF datasheet for the 2SA1797, a PNP bipolar transistor going by the JIS 2SA naming convention.

Filed under schematics, this 173 KB PDF is named after the 2SA965, a part number in the Japanese JIS scheme where the 2SA prefix marks a PNP bipolar transistor, so it is…

PDF of 64.4 KB for the 2SA1757, indexed as a schematic but bearing a JIS PNP bipolar transistor number, so it is a part datasheet.

Datasheet PDF, 90.4 KB, for the 2SA1702, named only by part number and filed under schematics.

PDF datasheet, 94.4 KB, for the 2N7002LT1, with rev2 in the name indicating the second revision of the document. It is filed as a schematic.

PDF of 168 KB for the JEDEC part 2N6667, with an RE suffix in the file name that is not explained and may simply mark a revised edition of the document.

Indexed as a schematic, a 295 KB PDF labelled 2N6426, from the JEDEC 2N series of discrete semiconductor part numbers.

At 275 KB, this PDF for the 2N6050 is one of the larger sheets in the set. It is indexed as a schematic, though it is most likely a full datasheet with curves.

Only the part code 2N5657 identifies this 497 KB PDF, which the index lists under schematics.

Revision-tagged PDF of 116 KB for part 2N5460, the rev0x token apparently marking a document edition whose exact number is not given.

Datasheet for the 2N5308 semiconductor, provided as a 56.9 KB PDF. The name contains only the part number and gives no manufacturer or revision.

Larger than most of its neighbours at 477 KB, this PDF covers the 2N4033 and may contain extra graphs, scanned pages or a multi-part data book extract; the name alone…

PDF reference for the 2N3820, only 26.3 KB, likely a short one- or two-page data sheet, although the index files it as a schematic.

Datasheet for the 1T363A, a 57.1 KB PDF indexed alongside schematics. The 1T prefix places it in the Soviet germanium transistor family, and the A suffix marks one…

This 52.5 KB PDF carries the code 1T406 and is indexed as a schematic, although the name says nothing about the equipment it belongs to.

Indexed under schematics, this small PDF of 42.7 KB is labelled 1T404A. That is the A variant of the 1T404 part code, which is catalogued separately.

Part code 1T399 names this 47.0 KB PDF, which is indexed as a schematic. The name gives no information about the product, brand or board number.
