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

The 2SK1920 is the only detail in this file name, and the 93.1 KB PDF is indexed as a schematic.

Part 2SK1890, documented in a 96.7 KB PDF placed in the schematic category. Japanese JIS numbering reserves 2SK for N-channel FETs, so this is a component datasheet…

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

Short 31.7 KB PDF for the 2SK1460LS, an N-channel FET by the Japanese 2SK prefix, carrying an LS suffix that distinguishes it from the plain 2SK1460 also in this index.

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

The 2SK1120 N-channel field-effect transistor is documented in this 455 KB PDF, one of the larger sheets in the set and probably including full characteristic curves and…

For the 2SJ579, this 42.7 KB PDF is indexed as a schematic, but a bare part-number name typically marks a datasheet.

The 2SJ407 is documented in this 398 KB PDF, catalogued as a schematic though it is a component datasheet by name.

Brief 24.7 KB PDF for the 2SJ0398, written with a leading zero in the name, which most likely refers to the 2SJ398 P-channel FET in JIS numbering.

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…

This 93.0 KB PDF carries the part number 2SJ258 and nothing else. The 2SJ prefix, under Japanese JIS numbering, indicates a P-channel field-effect transistor, so expect…

Named only 2SJ232, this 88.9 KB PDF relates to a P-channel field-effect transistor, as indicated by the JIS 2SJ prefix.

For the 2SD1011, this 42.1 KB PDF carries an _E tag in the name with no stated meaning.

Reference PDF for the 2SD973, 53.5 KB, with an _E suffix the name leaves undefined. It sits in the schematic category, but the JIS 2SD prefix marks an NPN transistor for…

A 126 KB PDF dedicated to the 2SC5257, sorted into the schematic section although the name identifies a single component.

Small 37.9 KB PDF for the 2SC4715, with an _E suffix in the name whose meaning is not stated, possibly a language or document edition marker.

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.

PDF reference for transistor part 2SC4428, 107 KB, indexed under the schematic category.

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

Only the part number 2SC5108 appears in the name of this 242 KB PDF, which is filed as a schematic but should be read as a transistor datasheet.

Part datasheet for the 2SC5589 in PDF, 298 KB, grouped with schematics in this index. The file name states only the part number.

Named only 2SC4213, this 289 KB PDF is catalogued as a schematic, yet the JEITA-style 2SC prefix identifies an NPN bipolar transistor, so a component datasheet is the…

Named 2SC5569 and weighing 50.3 KB, this PDF sits in the schematic category but refers only to a transistor part number.

A 129 KB PDF labelled 2SC5562, kept in the schematic section of the catalogue. The name holds only the part number; the 2SC prefix in JIS/JEITA naming identifies an NPN…

Compact 40.8 KB PDF for the 2SC536N, an NPN transistor under JIS numbering, where the trailing N is part of the stated part name.

A 29.5 KB PDF referencing the 2SC5792 transistor, an NPN device in the JIS-registered 2SC range.

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…

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.

Datasheet PDF for the base 2SC5417, 45.9 KB, filed in the schematic section; a separate LS-suffixed variant exists in the same set.

At 320 KB, the largest document in this group, this PDF is for the 2SC3862 transistor. The 2SC prefix follows the JIS scheme for NPN bipolar devices, so the content is…

Part documentation for the 2SC3777, a 127 KB PDF whose name identifies a single NPN transistor under the JIS 2SC numbering.

Compact 38 KB PDF named for the 2SC5380 transistor. The 2SC numbering marks an NPN device under the Japanese JIS scheme; the name gives no manufacturer or application.

Short 40 KB PDF named for the 2SC4913 transistor. The 2SC prefix marks an NPN bipolar device under JIS registration, and the name carries no further detail about maker…

The 2SC3689 transistor is the subject of this 89.7 KB PDF, which the catalogue lists as a schematic.

PDF document of 212 KB for the 2SC3620, filed under schematics but in practice a component datasheet for a discrete transistor.

Datasheet for the 2SC3613, a 241 KB PDF listed among schematic files although its content is a single-component specification.
