The 2SJ619 is the subject of this 314 KB PDF, indexed as a schematic though the naming suggests a component datasheet.

The 2SJ312 is documented in this 362 KB PDF, catalogued as a schematic. Beyond the part number the name says nothing about the equipment involved.

Roughly 96.6 KB PDF named for the 2SJ308. The name is limited to the part number and provides no model or board reference.

PDF of 245 KB titled 2SJ200, which by Japanese JIS convention is a P-channel field-effect transistor; the contents are probably the datasheet rather than a circuit…

PDF of 56.2 KB named 2SD1391, a JIS designation for an NPN low-frequency bipolar transistor, and presumably its datasheet although indexed under schematics.

Listed under schematics, this 110 KB PDF is named for the 2SD1347, an NPN bipolar transistor in the Japanese JIS 2SD series, and is probably its datasheet.

Documentation for the 2SC4623 transistor in PDF form, roughly 128 KB, indexed as a schematic although the part-number name indicates a datasheet.

The 2SC4527 data sheet, a 310 KB PDF filed under schematics but in practice a component specification.

PDF reference for the 2SC4248 transistor, 300 KB in size. Beyond the part number the file name gives no information about manufacturer, package or revision.

Part number 2SC5714 names this 166 KB PDF. Under the Japanese JIS scheme, 2SC parts are NPN bipolar transistors, so the document should list electrical ratings and a…

A 40.9 KB PDF titled 2SC3937 with the _E suffix often used for English versions of Japanese datasheets, listed here under schematics.

Specification sheet in PDF, 84.7 KB, for the 2SC3895 part. JIS numbering reserves the 2SC prefix for NPN bipolar transistors, so this is likely the device datasheet; no…

Reference sheet in PDF form, about 123 KB, for the 2SC5374 NPN transistor in the Japanese 2SC numbering series.

Listed under schematics, this 52.8 KB PDF refers to the 2SB1675, a PNP transistor in the Japanese JIS numbering system, so its content should be the part datasheet.

Indexed as a schematic, this 152 KB PDF for the 2SA1685 transistor is in all likelihood a manufacturer datasheet identified by its JIS code alone.

The 2SB1457 is covered by this 192 KB PDF, the largest of the group, filed as a schematic but named like a standard component datasheet.

Reference PDF, 88.9 KB, documenting the 2SA1654 transistor; only the part number is present in the name.

The 2SA1621 is covered by this 194 KB PDF, listed among schematics but really describing one discrete semiconductor.

Compact 39.7 KB PDF on the 2SB1370, indexed as a schematic though it documents one discrete device.

Indexed as a schematic, this compact 30.5 KB PDF is named for the 2SA1529, a JIS transistor number, and is best read as that part's datasheet.

Reference PDF of 136 KB for the 2SA1406 transistor, catalogued among schematics. The 2SA prefix, by JIS convention, marks a PNP device in the high-frequency category.

The 2SA1370 is a PNP transistor in the Japanese JIS numbering system, and this 138 KB PDF is named after it alone.

162 KB PDF for the 2SB772, a widely used PNP power transistor with a JIS part number, where 2SB stands for a low-frequency PNP device.

Compact 40.8 KB PDF for the 2SA1257, indexed as a schematic though its name carries only a part number.

PDF data for the 2SA1838, sized 87.4 KB and stored in the schematic category of the index.

The 2SA1091 is covered by this 334 KB PDF, the largest of this group, filed in the schematic category.

PDF datasheet of 42.8 KB for the 2SA1011 transistor, catalogued in the schematic category though it is really component reference data.

Catalogued as a schematic, this 182 KB PDF carries the name of the JEDEC-registered discrete semiconductor 2N6547, with an RE suffix whose meaning the name does not…

Compact 51.7 KB PDF documenting the 2N4036, filed under schematics though its JEDEC-style name indicates a discrete component datasheet.

Reference sheet in PDF format, 137 KB, for the 2SD1840 transistor from the 2SD family of NPN bipolar devices; despite the schematic label, expect datasheet content.

PDF of 363 KB for the 2SK192A, listed among schematics but named after a single JIS part, with an A suffix that the name explicitly includes.

For the 2SK3114, a 94.1 KB PDF supplies the component data, filed among the schematics.
