Datasheet-type PDF for the 2SD1878, 90.6 KB, placed in the schematic category of the index. The name contains nothing beyond the part number.

Named 2SD2426, this 69.1 KB PDF is filed as a schematic, though the 2SD prefix follows the Japanese JIS code for NPN bipolar transistors and points to a single-part…

Component reference for the 2SD1993, a 45.5 KB PDF listed among schematics. Following Japanese JIS part numbering, 2SD identifies an NPN bipolar transistor of the…

A 318 KB PDF covering the 2SK2882, listed under schematics but almost certainly a datasheet given the bare part number in its name.

Covering the 2SK2865, this 424 KB PDF sits in the schematic category but, judging by its name, is the component datasheet.

Listed as a schematic, this 412 KB PDF carries only the part number 2SK2845 in its name.

The 2sk2790 name on this tiny 21.3 KB PDF is the only information provided. Filed as a schematic, it most probably holds a brief datasheet for an N-channel field-effect…

PDF of 410 KB for the 2SK2717, recorded as a schematic but named after a single semiconductor part.

Covering the 2sk2580, this 34.5 KB PDF is labelled a schematic yet identifies only a semiconductor part, pointing to a short datasheet.

Short 34.8 KB datasheet-style PDF for the 2sk2576, an N-channel FET under the Japanese JIS 2SK designation.

Covering the 2SK2459N, this 138 KB PDF sits in the schematic section but by its name is a transistor datasheet; 2SK is the Japanese JIS prefix for N-channel field-effect…

A 32.6 KB PDF covering the 2SK2325, a Japanese-registered semiconductor whose 2SK prefix means N-channel field-effect transistor.

A PDF of about 88 KB for the 2SK2154, filed under schematics but most likely a component datasheet, since the name is just the part number.

Reference sheet for the 2SK2046, supplied as an 88.4 KB PDF. The 2SK designation belongs to the Japanese registration scheme for N-channel field-effect transistors…

Datasheet in a 33.2 KB PDF for the 2SK1967, a Japanese-registered N-channel field-effect transistor indicated by the 2SK prefix.

A 95.0 KB PDF named after the 2SK1908, listed in the schematic section of the index. Since 2SK is the Japanese registration prefix for N-channel FETs, treat it as the…

PDF, 121 KB, for the 2SK1474 transistor. Japanese 2SK numbering denotes an N-channel field-effect device, so although the index category is schematic, the content is…

Listed as a schematic, this 125 KB PDF is named after the 2SK1466, a part code that under the Japanese JIS scheme denotes an N-channel field-effect transistor.

The 2SK1449 gives this 109 KB PDF its name, and nothing else is stated. It is filed as a schematic, though it is probably the device data sheet.

The 2SK1375 N-channel field-effect transistor is covered by this 150 KB PDF, filed under schematics in the catalogue.

Datasheet-style PDF for the 2SK1117, with the name noting NTE2379 as its equivalent, meaning the NTE replacement line lists that part as a cross-reference.

Component sheet for the 2SK1069, an N-channel FET from the Japanese 2SK numbering range, stored as a 98.7 KB PDF.

A PDF filed under schematics but named after the 2SK404, a part number in the Japanese JIS semiconductor scheme, where the 2SK prefix marks an N-channel field-effect…

Datasheet-style PDF of 105 pages' worth of nothing more than a part number: the 2SJ420, a device whose 2SJ prefix under Japanese JIS designation identifies a P-channel…

PDF document for the 2SJ346, filed in the index as a schematic but named after a discrete semiconductor part.

An 82.4 KB PDF bearing only the part number 2SJ188; the 2SJ prefix in Japanese numbering denotes a P-channel field-effect transistor, so this is likely its datasheet…

The 2SC4690 is the subject of this 175 KB PDF, which the index files as a schematic even though the name points to a single transistor document.

Named after the transistor type 2SC4646, this 148 KB PDF most likely contains the part datasheet. No board, model or revision is mentioned.

Catalogued as a schematic, this 184 KB PDF is named only after the part number 2SC5175, so it is most likely the manufacturer datasheet for that discrete transistor.

Datasheet-style PDF of 88.2 KB for the semiconductor 2SC4475, catalogued in the schematic section.

Datasheet-style PDF of 119 KB for the 2SC4401, listed in the index under schematics although the name points to a single semiconductor part.

The name of this 156 KB PDF is just the part number 2SC4134, so despite its schematic label it should be the datasheet for that transistor.

A 475 KB PDF referencing the 2SC5092 transistor type; the 2SC prefix denotes an NPN bipolar device under the Japanese JIS numbering system.

Reference document for the 2SC5089 NPN transistor, supplied as a 465 KB PDF and filed with schematics.
