Part number 2SD2459 names this 41.2 KB PDF, followed by an unexplained E tag; it is catalogued as a schematic.

Largest in this set at 269 KB, the PDF 2SD2414 is catalogued as a schematic, yet its 2SD prefix marks an NPN bipolar transistor under the Japanese JIS scheme.

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

The name carries only a part number, 2SD1905, which points to a semiconductor datasheet even though the entry is filed under schematics.

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

Tiny 30.2 KB PDF named 2sk65, a JIS part number that indicates a component datasheet, although it is filed as a schematic.

Datasheet-type PDF of 31.1 KB for the 2SK3412 semiconductor, stored under the schematic category.

PDF reference for the 2SK2825, 301 KB in size and listed in the schematic section. The 2SK designation, from the Japanese JIS numbering system, belongs to N-channel…

The 2SK2718 is documented in a 412 KB PDF that the catalogue files under schematics, though by its name it is a component datasheet.

Brief PDF, about 30.2 KB, for the 2SK2509, a JIS-designated N-channel FET as indicated by its 2SK prefix.

The 2SK2504 transistor is documented in this 134 KB PDF, named in lowercase and catalogued under schematics.

Indexed as a schematic, this 99.3 KB PDF is titled 2SK2406 and is most probably a datasheet for an N-channel field-effect transistor, as the 2SK prefix indicates under…

Datasheet-style PDF, 55.1 KB, for the 2SK2347 semiconductor, stored in the schematic section of the index.

A 423 KB PDF referencing the 2SK2311, with no details in the name beyond the part number.

A 396 KB PDF for the 2SK2274, listed under schematics but most likely a datasheet, since 2SK denotes an N-channel FET in the JIS numbering scheme.

Part number 2SK2231 is the only information carried by this 420 KB PDF, which the index places among schematics but which most likely documents a single transistor.

Compact 31.6 KB PDF dedicated to the 2SK2032. Because 2SK identifies an N-channel field-effect transistor in the Japanese numbering scheme, this is effectively a…

Component documentation in a 114 KB PDF for the 2SK2011. Parts with the 2SK prefix are N-channel field-effect transistors under the Japanese numbering standard, so this…

PDF reference, 115 KB, for the 2SK1924 N-channel field-effect transistor; the 2SK prefix places it in the Japanese JIS transistor registry.

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 2SK1826 datasheet in PDF form, sized 320 KB and filed as a schematic. Japanese JIS designations starting with 2SK identify N-channel field-effect transistors.

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.

PDF documentation for the 2SK1731 discrete semiconductor, roughly 90 KB in size. Japanese 2SK numbering identifies it as an N-channel FET; the name says nothing about…

At 120 KB, this PDF is a slightly larger reference for the 2SK1728. Japanese JIS/JEITA numbering assigns the 2SK series to N-channel field-effect transistors, so expect…

For the 2SK1470, a Japanese-coded N-channel field-effect transistor, this 97.9 KB PDF serves as component reference material even though it sits in the schematic…

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

Reference document for the 2SK1436 transistor, supplied as a 105 KB PDF and listed under schematics.

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.

Sheet for the 2SK1310A, an N-channel field-effect transistor in the Japanese 2SK series, supplied as a 175 KB PDF.

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…

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

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

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

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

Reference sheet for the 2SD1062 transistor in PDF form, about 104 KB, catalogued under schematics.
