Very small 26 KB RAR archive labelled AO4600, an Alpha and Omega Semiconductor MOSFET part number, a complementary N and P channel pair in SO-8.

Small 91.1 KB PDF named sn608098, filed as a schematic. The name does not reveal the device; it may be a Texas Instruments component number, though that cannot be…

Schematic diagram in PDF for the IBM ThinkPad R40, roughly 1.45 MB; the name gives no board number or revision.

Datasheet for the 4N25 phototransistor optocoupler, a classic six-pin DIP isolator used in power supplies, interfaces and control circuits.

A 41.4 KB PDF covering the 5HP02C part, indexed under schematics. Only the component code is present in the name, with C most likely denoting the package type.

Component documentation for the 4N38 optocoupler, filed under schematics though it is in practice a part datasheet in PDF form of about 140 KB.

Part datasheet for the 2SD1782K, an NPN transistor named under the Japanese JIS scheme, with the K suffix indicating a particular variant or package.

The 2SD1683 is the subject of this 146 KB PDF, which is catalogued as a schematic although the name is a transistor part number.

Part reference for the 2SD1669, supplied as a 107 KB PDF and filed in the schematic section.

Datasheet PDF, 60 KB, for the 2SD1650, with the name given in lowercase and filed under schematics.

The 2SD1628 is covered in this 88.3 KB PDF, catalogued with schematics though it relates to a single transistor.

Part number 2SD1424 with an unexplained _E suffix names this 41.4 KB PDF, indexed among schematics but most likely a datasheet for the transistor.

PDF covering the 2SD1880, about 88.9 KB, listed as a schematic but named after a single semiconductor part.

Reference sheet for the 3SK180 semiconductor in PDF form, roughly 173 KB, catalogued as a schematic.

Compact 43.6 KB PDF named for the 3N249 and filed as a schematic, although it is almost certainly a component datasheet.

Short 54.7 KB PDF for the 2SD1991A, an NPN bipolar transistor going by its JIS 2SD prefix. The index lists it under schematics.

The 2SD1511 NPN transistor is the subject of this 56.9 KB PDF, filed under schematics in the index. JIS numbering assigns 2SD to low-frequency NPN bipolar parts.

For the 2SK3411 transistor, this 32.0 KB PDF provides the component reference, even though the index files it as a schematic.

The 2SK3291 transistor is the subject of this 34.2 KB PDF, filed as a schematic although it works as a datasheet.

Here the 2SK3285 is documented in a 48.6 KB PDF, placed in the index's schematic section.

Datasheet-style PDF for the 2SK3018, indexed here under schematics, though the 2SK prefix marks a Japanese JIS-registered N-channel field-effect transistor rather than a…

The name of this 421 KB PDF carries just one token, 2SK2836, a JIS-format number for an N-channel FET.

Reference sheet in PDF format for the 2SK2549 field-effect transistor, 373 KB in size. In the JIS numbering used by Japanese semiconductor makers, 2SK denotes an…

Small 33.8 KB PDF on the 2sk2495, a part number in the JIS N-channel FET series marked by the 2SK prefix.

Filed under schematics, this 138 KB PDF is named after the 2SK2463, a JIS-style part number, so it is most likely a component datasheet rather than a board drawing.

For the 2SK2313 transistor, this 419 KB PDF is filed as a schematic but is expected to be a datasheet, since 2SK is the JIS prefix for N-channel FETs.

The 2SK2312 is covered by this 391 KB PDF, catalogued under schematics yet most likely a component datasheet.

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.

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