Schematic for the ThinkPad R60 laptop, supplied as a 1.63 MB PDF. The name states only the model, so the board revision must be checked on the PCB before matching parts.

Small PDF reference named only by the part number 2SK2740, filed as a schematic but most likely the component datasheet for this 2SK-series N-channel FET.

Covering the 2SD2578 transistor, this 45.0 KB PDF sits in the schematic category but is probably a manufacturer datasheet.

Datasheet for the 2SD2131 transistor, provided as a 240 KB PDF in the schematic section.

Component data for the 2sd2396, supplied as a 42.0 KB PDF and indexed under schematics.

Compact 39.6 KB PDF for the 2SD2359, catalogued among schematics but by its name a transistor datasheet.

Covering the 2SK3119 transistor, this 149 KB PDF is indexed as a schematic but is in practice a component sheet.

This 55 KB PDF is labelled 2SK2220 and indexed under schematics, though a part-number name usually means the datasheet of a single semiconductor.

Catalogued under schematics, this 121 KB PDF titled 2SK2167 most likely holds the datasheet for that transistor.

PDF of 130 KB for the 2SK2094, listed as a schematic and most likely a datasheet for this JIS-designated N-channel FET.

Indexed as a schematic, this 107 KB PDF refers to the 2SK1440, and the name states nothing beyond the part number.

Part reference for the 2SK1259, a 37.4 KB PDF covering an N-channel FET in the Japanese 2SK series.

Datasheet for the 2SK1035 transistor, stored as a 35.3 KB PDF. Under JIS numbering, the 2SK prefix means an N-channel FET.

Component document for the 2SK212 in PDF form, 156 KB, indexed under schematics. Japanese JIS numbering assigns the 2SK prefix to N-channel FETs, so the file should be…

Component sheet for the 2SD1191, delivered as a 143 KB PDF and categorised as a schematic, though the name suggests a datasheet for a single part.

PDF document of 94.9 KB for the 2SC5299, a JIS-registered NPN transistor designation. Although catalogued as a schematic, files named after a part number like this are…

Component documentation for the 2SC5279 in a 124 KB PDF. Under Japanese naming, 2SC means an NPN bipolar transistor, so the content is expected to be a datasheet rather…

Compact 52.7 KB PDF for the 2SC4731, indexed as a schematic though its name identifies a single semiconductor.

Brief 68.6 KB PDF bearing the number 2SC4681, placed under schematics. The 2SC prefix is JIS shorthand for an NPN bipolar transistor, so treat the file as the part…

Here the 2SC5231 is covered by a 133 KB PDF that the catalogue files under schematics, although it most likely is a transistor datasheet.

Reference PDF for the 2SC5227 transistor, 128 KB in size and indexed under schematics. The 2SC designation follows the JIS convention for NPN bipolar parts.

Specification sheet for the 2SC4521 transistor, delivered as an 87.4 KB PDF. Following JIS numbering, 2SC denotes an NPN bipolar part; the catalogue tags it as a…

A 144 KB PDF specification for the 2SC4481 transistor, filed as a schematic but in fact a component datasheet.

Datasheet-type PDF of 132 KB covering transistor 2SC4438, filed with the schematics in this index.

Small 58.3 KB PDF titled 2sc5103 in lower case, catalogued as a schematic yet evidently a short datasheet for the 2SC5103.

The 2SC5098 transistor is the only identifier in this 298 KB PDF, which the index files under schematics.
