A 277 KB PDF covering the 2SD2539, a part number in the JIS 2SD family, which denotes NPN bipolar transistors for low-frequency circuits.

PDF of about 179 KB for the 2SD2531, filed as a schematic but probably the component datasheet.

A 107 KB PDF titled with the lowercase part number 2sd1565, catalogued as a schematic yet almost certainly a transistor datasheet.

Datasheet-type PDF for the 3SK271, around 32.7 KB, catalogued in the schematic category.

The 2SK3092 is described in this compact 31.3 KB PDF, catalogued as a schematic but acting as a datasheet. Under JEITA designations, a 2SK part is an N-channel FET.

Datasheet for the 2SK2968 in a 405 KB PDF, categorised with schematics but describing one discrete device.

Covering the 2SK2952, this PDF of 414 KB is a discrete transistor document rather than a full circuit, as the JIS 2SK prefix indicates an N-channel field-effect…

A 413 KB PDF for the 2SK2699 transistor, filed as a schematic in this index. The 2SK prefix identifies it as a JIS-registered N-channel field-effect transistor, so the…

A 139 KB PDF for the 2SK2623, which JIS numbering identifies as an N-channel FET. Although indexed as a schematic, it is effectively a component datasheet with limits…

Document for the 2SK2493 field-effect transistor in PDF form, 384 KB, listed under schematics in the catalogue.

Reference sheet for the 2SK2382, a 412 KB PDF placed under schematics, though the JIS-format number marks it as a datasheet for an N-channel FET.

A short 28.8 KB PDF for the 2SK2379, indexed as a schematic though it is almost certainly a component datasheet; JIS numbers starting with 2SK denote N-channel…

Titled 2SK2378, this 26.7 KB PDF is the smallest in its series and is listed under schematics, but the JIS part number indicates a datasheet for an N-channel FET.

Covering the 2SK2095N N-channel field-effect transistor, this 128 KB PDF is catalogued under schematics but is presumably a datasheet.

The 2SK2094 N-channel FET is the subject of this 127 KB PDF, which is catalogued as a schematic though the bare part-number name points to a datasheet.

The name pairs the 2SK2078 with STW9NA80, an STMicroelectronics-style part number, so this 133 KB PDF may cover both devices or present one as an equivalent.

Reference sheet in PDF form (98.9 KB) for the 2SK1909 transistor, catalogued under schematics.

Small 36.4 KB PDF for the 2SK1614, an N-channel field-effect transistor according to the Japanese 2SK designation.

PDF datasheet, 117 KB, for the 2SK1460, a Japanese-designated N-channel field-effect transistor, filed under schematics in the catalogue.

A 109 KB PDF for the 2SK1439, filed with schematics but most likely the manufacturer's data sheet for this transistor. The JIS 2SK prefix denotes an N-channel FET.

The 2SK1420, an N-channel FET according to the Japanese JIS 2SK prefix, is the subject of this 103 KB PDF.

PDF for the 2SK1238, a Japanese 2SK-series N-channel MOSFET, size 45.9 KB. No manufacturer, package or revision appears in the file name, so match the printed marking on…

Reference datasheet for the 2SK1052, delivered as a 104 KB PDF with no other details in the name.

A 294 KB PDF for the 2SK209, filed as a schematic. In JIS semiconductor nomenclature the 2SK series is N-channel FETs, so this is effectively a component datasheet.

A 32.3 KB PDF for the 2SJ591LS, filed under schematics but named like a transistor datasheet.

The 2SJ305 is described in this 335 KB PDF, listed among schematics. No board number or brand appears in the name.

Reference PDF for the 2SD1197 transistor, 134 KB in size and indexed as a schematic, though the file name is only a part number and reads as a datasheet.

The name carries only the part number 2SD1195, so this 148 KB PDF is best treated as the datasheet for that transistor, even though the index labels it a schematic.

PDF datasheet for the 2SD1133, 43.0 KB, listed among schematics though its name refers only to the part.

Datasheet-style PDF, 99.8 KB, for the 2SC5296 transistor. Under Japanese JIS naming, 2SC parts are NPN bipolar types, so expect specifications rather than a full circuit…

Compact 27.2 KB PDF on the 2SC5291. The 2SC prefix identifies an NPN bipolar transistor in the JIS system, so this is most likely a short manufacturer datasheet, filed…

The 2SC5273 is the subject of this 42.0 KB PDF. As a JIS-registered 2SC device it is an NPN bipolar transistor, and the file is likely its datasheet rather than a full…

A 35.0 KB PDF relating to the 2SC5270. The 2SC prefix denotes an NPN bipolar transistor in the Japanese JIS system, so the document is most probably a compact datasheet…

The 2SC4735 is covered by this 109 KB PDF, listed under schematics but named purely by part number.

The 2SC4685 is documented in this 186 KB PDF, filed as a schematic though the name is a transistor part number.

Transistor documentation for the 2SC4678 in a 220 KB PDF file, sorted into the schematic category.

This 28.6 KB PDF carries the part number 2SC4635LS, apparently a package or lead-form variant of the 2SC4635 NPN transistor.
