Datasheet PDF, 60 KB, for the 2SD1650, with the name given in lowercase and filed under schematics.

The 2SD1628 is covered in this 88.3 KB PDF, catalogued with schematics though it relates to a single transistor.

Indexed as a schematic, this 109 KB PDF is titled 2SD1621, a transistor part number, so treat it as a datasheet rather than a circuit diagram.

PDF covering the 2SD1880, about 88.9 KB, listed as a schematic but named after a single semiconductor part.

Compact 43.6 KB PDF named for the 3N249 and filed as a schematic, although it is almost certainly a component datasheet.

The 3N248 is covered by this 43.6 KB PDF, indexed under schematics but named only by its JEDEC part number.

PDF document for the 2SD1995 semiconductor, catalogued under schematics but by its name a component datasheet.

Filed under schematics, though the file name is simply the JIS part number 2SD1903, so expect a component datasheet in this 131 KB PDF.

Covering the 2SK3335, this small PDF (32.6 KB) is a part datasheet placed in the schematic category.

Reference PDF for the 2SK2711, about 140 KB, listed in the schematic category though the part number points to a discrete transistor datasheet.

The 2SK2312 is covered by this 391 KB PDF, catalogued under schematics yet most likely a component datasheet.

PDF datasheet of 287 KB for the 2SK2009, an N-channel field-effect transistor under the Japanese 2SK designation.

PDF datasheet, 173 KB, covering the 2SK1740. The 2SK series in JIS nomenclature consists of N-channel FETs, and this document is likely its specification sheet.

The 2SK1468 transistor is covered by this 92.5 KB PDF, categorised as a schematic though the name is purely a part number.

Covering the 2SK1435, this 105 KB PDF is indexed as a schematic yet named after one discrete component, which suggests a datasheet.

Small 33.4 KB PDF covering the 2SK1406 field-effect transistor from the Japanese 2SK numbering series, which designates N-channel FETs.

PDF covering the 2SK1104, an N-channel FET identified by the 2SK prefix of the Japanese semiconductor numbering system.

Covering the 2SJ612, this 29.0 KB PDF sits in the schematic category, though a bare part number usually denotes a datasheet.

Covering the 2SJ589LS, this 33.2 KB PDF is catalogued as a schematic, though the name points to a component datasheet.

The 2SJ377 is covered by this 415 KB PDF, a component datasheet filed in the schematic category.

Catalogued among schematics, this 103 KB PDF is labelled only 2SJ263. In the Japanese JIS designation system the 2SJ prefix covers P-channel field-effect transistors, so…

The 2SC5238 is covered by this 105 KB PDF, filed among schematics but named like a discrete-component datasheet.

Small 56 KB PDF covering the 2SC4626 part, with an _E suffix that possibly marks an English-language version of the original document.

Small 39.3 KB PDF covering the 2SC4562, with an unexplained _E suffix in the name, listed under schematics.

A 105 KB PDF covering the 2SC4426, filed as a schematic although the name is a component number.

PDF of 208 KB covering the 2SC5550, listed in the index under schematics but by its JIS part code an NPN bipolar transistor, so treat it as a component datasheet.

Reference PDF for the 2SC5489, 31.3 KB in size and filed as a schematic. In the Japanese JIS convention the 2SC prefix identifies an NPN transistor, so the document is…

The 2SC5488 is covered by this 34.5 KB PDF, indexed as a schematic. Since 2SC numbers designate NPN bipolar transistors in the Japanese JIS system, the file is likely a…

Brief 41.9 KB PDF for the 2SC5453, in the JIS 2SC range that denotes NPN transistors. Catalogued as a schematic, it is most plausibly a short datasheet covering the…

A 39.2 KB PDF for the 2SC3956 transistor, indexed as a schematic but by its name a datasheet for a JIS-designated NPN bipolar device.

Catalogued among schematics, this 224 KB PDF covers the 2SC3709A transistor. By JIS convention the 2SC prefix denotes an NPN bipolar device, and the A suffix indicates a…

Covering the 2SC3150 transistor, this 103 KB PDF sits in the schematic category of the index.

A PDF for part 2SC3083, 98.2 KB in size and catalogued under schematics, though the name suggests a datasheet. Only the part code is given.

Small 42.4 KB PDF for the 2SC2634, carrying an _E suffix that may mean an English edition, though the name does not state it.

The 2SC2073A, an A-suffixed variant of a JIS-numbered part, is covered by this 154 KB PDF listed as a schematic.

Indexed as a schematic, this 199 KB PDF actually carries only the part number 2SC1959, pointing to a single NPN bipolar transistor under the JIS naming scheme.

The 2SC1755 is covered by this 53.2 KB PDF, which the index lists as a schematic although the name refers to one component.

Reference PDF covering the 2SB1530 transistor, filed under schematics but in practice a component datasheet identified only by its JIS part code.

Short PDF of 38.2 KB covering the 2SA1635, a part number that follows the Japanese JIS scheme where 2SA identifies a high-frequency PNP bipolar transistor.

A 214 KB PDF for the 2SA1429 part, catalogued as a schematic though most likely a data sheet.
