The name 2sd1455 refers to a JIS-registered NPN transistor, and this 53.0 KB PDF is most likely its manufacturer datasheet, although the index lists it as a schematic.

A fairly detailed 200 KB PDF for the 2SD2352, a JIS-numbered NPN transistor, where the 2SD prefix denotes NPN low-frequency parts.

Stored under a lowercase name, this 52.3 KB PDF covers the 2sd2318 transistor. In the Japanese JIS scheme the 2SD series contains NPN devices for low-frequency duty, so…

PDF document for the 2SK2775, filed under schematics although the part number points to a component datasheet rather than a board drawing.

A compact 23.3 KB PDF for the 2SK2772, an N-channel FET according to the JIS 2SK naming convention, catalogued here as a schematic.

The 2SK2750 is covered by this 394 KB PDF, indexed as a schematic but most likely the component datasheet, since 2SK is the JIS prefix for N-channel FETs.

A 135 KB PDF covering the 2SK2711 transistor. The extra 1-5 token in the name is not explained and may point to a page range or document revision.

The smallest sheet of its group at 24.4 KB, this PDF concerns the 2sk2573, an N-channel field-effect transistor by the JIS 2SK prefix.

The name 2SK1446LS marks this 32 KB PDF as covering an LS-suffixed version of the 2SK1446.

Datasheet-style PDF for the 2SK1412LS, a Japanese 2SK-series N-channel field-effect transistor, filed in the index under schematics.

Datasheet-style PDF for the 2SK669, a part number in the JIS 2SK series used for N-channel field-effect transistors, listed in the index as a schematic.

Reference PDF for the 2SK620, a JIS-series N-channel field-effect transistor, weighing 35.6 KB and listed under schematics though it is most likely a datasheet.

Only the part number 2SJ512 appears in the name of this 455 KB PDF, which the index lists among schematics.

At just 31.4 KB, the PDF named 2SJ499 is probably a short datasheet or summary sheet, even though it is filed as a schematic.

The 2SJ419 is covered by this 100 KB PDF, filed under schematics though the part number points to a discrete transistor datasheet.

Catalogued as a schematic, this 93.1 KB PDF is named only after the part number 2SJ281, which follows the Japanese JIS scheme where the 2SJ prefix denotes a P-channel…

At 294 KB, this PDF is larger than its neighbours but still identified only by 2SJ167, a Japanese JIS number for a P-channel field-effect transistor.

Indexed as a schematic, the 44.5 KB PDF named 2SD1328_E should be a datasheet for the 2SD1328, which the JIS 2SD prefix identifies as an NPN bipolar transistor for…

Small 31.3 KB PDF covering the 2SC5265LS, filed as a schematic. The 2SC prefix in the JIS system identifies an NPN bipolar transistor, and the LS suffix marks a variant…

PDF document of 41.7 KB for the 2SC4737, filed in the schematic category but named after a part rather than a board.

Filed under schematics, this 98 KB PDF is named after the part number 2SC4671, which follows the Japanese JIS designation for an NPN bipolar transistor.

This 39.4 KB PDF is labelled 2SC4656 with an E suffix. The E most likely marks an English edition from a Japanese maker, but the name does not say so outright.

Datasheet in PDF form for the 2SC4696, filed in the index under schematics although the name points to a discrete part document rather than a board diagram.

The 2SC4163 part number is all this 98.9 KB PDF name reveals, so although labelled a schematic it is best read as a transistor datasheet.

Named only 2SC4161, this 98.6 KB PDF is categorised as a schematic yet, judging by the part number, documents an NPN bipolar transistor under the JIS designation scheme.

Named in lowercase for the 2sc4132, this 63.0 KB PDF is classed as a schematic but is better understood as the datasheet for an NPN bipolar transistor, which is what the…

The largest of this group at 334 KB, this PDF is named only 2SC4117 and, while labelled a schematic, should be the datasheet for that NPN bipolar transistor under…

Small 95.8 KB PDF for the 2SC4109, indexed with the schematics. The file name gives nothing beyond the part number; the 2SC prefix identifies an NPN bipolar transistor…

Datasheet-sized PDF of 38.0 KB for the 2SC5474, with an _E suffix in the name that likely marks an English edition; that reading is an inference.

A compact 21.2 KB PDF titled after the 2SC4080, stored as a schematic but best treated as a transistor datasheet. JIS numbering uses 2SC for NPN bipolar transistors.

For the 2SC4006 there is this 79.6 KB PDF, filed as a schematic though a bare JIS code like this normally names a datasheet.

Named for the 2SC4003, this 79.4 KB PDF is listed as a schematic but appears to be a transistor datasheet.

A 129 KB PDF filed under schematics, though its name, 2SC3807, is simply a transistor type number.

Covering the 2SC3599, this 124 KB PDF is a discrete transistor datasheet even though it is filed as a schematic.

The 2SC5323 is the only clue in this file name, so treat this 122 KB PDF as a probable transistor datasheet even though it sits in the schematic category.

Compact 128 KB PDF bearing the part number 2SC2983, indexed as a schematic. Under the Japanese JIS naming convention a 2SC number denotes an NPN bipolar transistor, so…

Filed under schematics, this 49.7 KB PDF covers the 2SC1318A, an NPN transistor in JIS numbering; the A suffix denotes a variant of the base 2SC1318 type, often with…

At 190 KB this PDF is larger than most entries here and is named for the 2SC982, an NPN transistor according to the JIS 2SC prefix; the TM suffix in the name is not…

Catalogued among schematics, this 54.5 KB PDF is named for the 2SB642, which the JIS 2SB prefix marks as a PNP transistor; the document is therefore expected to be a…

English-edition datasheet, judging by the _E suffix, for the 2SB1599 PNP bipolar transistor, 43.5 KB in PDF.
