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

PDF documentation, around 108 KB, for the 2SD2150 NPN transistor under the Japanese 2SD numbering system.

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

PDF datasheet of 137 KB for the 2SK3120, sorted into the schematic category of the index.

A 417 KB PDF on the 2SK2967 transistor. The name gives only the part code, and 2SK designates an N-channel FET in the Japanese JIS scheme, so this is a component…

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.

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 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.

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

The 2SK1413 is documented in this 112 KB PDF, listed under schematics but named after a single discrete part, which points to a datasheet.

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

The 2SJ349 P-channel FET is described in a 418 KB PDF, catalogued under schematics though it is a component datasheet.

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.

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…

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

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

Here is the 106 KB datasheet-style PDF for 2SC4637, a JIS-numbered NPN bipolar transistor.

Here is a 178 KB PDF for the 2SC5254, a Japanese JIS-registered NPN bipolar transistor, most probably its datasheet.

PDF file of 129 KB titled with the part number 2SC5228, catalogued as a schematic but best treated as a transistor datasheet.

Filed as a schematic, this 192 KB PDF carries just the identifier 2SC5172, which indicates a datasheet for a discrete NPN bipolar transistor following the JIS 2SC naming…

2SC4579 datasheet candidate in PDF form, 102 KB, categorised as a schematic. The name follows the JIS convention in which 2SC denotes an NPN bipolar transistor for…

Filed as a schematic, the 124 KB PDF titled 2SC4555 names a discrete transistor, so its content is probably the datasheet.

For the 2SC4489 NPN bipolar transistor, as indicated by the JIS 2SC prefix, this 154 KB PDF serves as the component datasheet even though it is catalogued under…

Datasheet candidate for the 2SC4455 transistor, a 100 KB PDF although filed with schematics.

Named after transistor 2SC4452, this 98.8 KB PDF is listed as a schematic but most likely contains the component datasheet.

The smaller 77.9 KB PDF here carries the type number 2SC4449, indexed as a schematic but almost certainly a component datasheet.

PDF of 51.8 KB for the 2SC5610 transistor, indexed with schematics although the bare part number suggests a manufacturer datasheet.

Here is a 297 KB PDF named 2SC5590, sorted under schematics but bearing only a component number, so it should be the datasheet for that part.

Filed among schematics, this 467 KB PDF carries just the transistor number 2SC4320 and should be regarded as its datasheet.
