Specification document, 405 KB in PDF form, for the 2SK2604 transistor. Japanese JIS part numbering assigns the 2SK prefix to N-channel field-effect transistors; beyond…

A 34.5 KB PDF for the 2sk2579, indexed with schematics but named only by part number, so it is most likely a compact component datasheet.

Covering the 2sk2571, this 24.5 KB PDF is a short document classed as a schematic, though its name is just a part number and the content is likely a concise datasheet.

PDF reference for the 2SK2551, a part named under the Japanese JIS scheme where 2SK identifies an N-channel field-effect transistor.

PDF of 111 KB describing the 2SK2467, catalogued as a schematic but named for a discrete transistor.

Listed as a schematic, the 95.7 KB PDF bearing part number 2SK2160 is most likely the datasheet for an N-channel field-effect transistor.

The 2SK1900 transistor is the subject of this 99.3 KB PDF, catalogued with schematics. Under the JIS convention, 2SK designates an N-channel field-effect transistor, so…

Here is the 389 KB PDF for the 2SK1359 MOSFET, part of the Japanese 2SK family of N-channel field-effect transistors.

Component documentation for the 2SK1119, a part number in the Japanese 2SK series that designates N-channel field-effect transistors.

PDF document for the 2SK715 part number, catalogued under schematics but almost certainly a component datasheet, since the 2SK prefix follows the Japanese JIS…

PDF document of 171 KB for the 2SD1314, indexed as a schematic although the part number points to a component datasheet rather than a board drawing.

Datasheet-type PDF for the 2SD1145 transistor, 89.8 KB, placed in the schematic category of the index.

Here is a 37.0 KB PDF for the 2SD1030, named with an _E suffix that is not explained in the file name.

The 2SD863 transistor datasheet, a 96 KB PDF with no maker named in the file title. JIS numbering identifies 2SD devices as NPN transistors aimed at low-frequency…

Reference datasheet in PDF format, about 133 KB, describing the 2SD826 transistor; the source manufacturer is not given in the name.

PDF component datasheet for the 2SD734 transistor, about 103 KB, filed under schematics though it documents a single part.

Listed as a schematic, this 183 KB PDF actually relates to the 2SC5259 part. JIS numbering places the 2SC prefix on NPN bipolar transistors, so the content is expected…

Compact 36.0 KB PDF covering the 2SC5244, listed as a schematic though the file name matches a single semiconductor part number.

Component sheet for the 2SC4410 with an unexplained _E suffix, delivered as a 41.6 KB PDF.

PDF documentation for the 2SC5149, the largest of this batch at 193 KB. Under the Japanese JIS scheme the 2SC prefix denotes an NPN bipolar transistor, so the content…

Datasheet PDF for the 2SC4405, 113 KB in size. The name holds only the part number, and the JIS 2SC prefix tells us it is an NPN bipolar transistor rather than a board.

Compact 32.8 KB PDF labelled 2SC5645, filed among schematics but most probably a single-part datasheet for that transistor.

The largest of this group at 465 KB, the PDF named 2SC4394 is most likely a full datasheet for that transistor rather than a board schematic, despite its index label.

Named 2SC5637, this 42.7 KB PDF is listed as a schematic but is presumably the datasheet for that transistor.

The 2SC4249 transistor is the subject of this 263 KB PDF, filed under schematics. The name carries the part number alone, so maker and revision are not stated.
