Schematic in PDF format, 4.09 MB, filed under the code ua23h4003ar, which looks like a Samsung TV model number for a 23 inch set, although the name gives no other…

Schematic for the HP 2000-2301TU, HP 650 and Compaq CQ68 laptops, a 1.02 MB PDF. Its size matches the NEWTON CR&HR version and it is likely the same document under a…

An 88.0 KB PDF for the 2SD1838, a Japanese-registered NPN bipolar transistor, best treated as a datasheet even though it is indexed as a schematic.

Compact 46 KB PDF datasheet for the 2SD1757K, an NPN transistor under Japanese JIS designation, with a K suffix marking its variant.

PDF reference for the 2SK2993 transistor, 424 KB. The file name carries only the part number, which under the JIS scheme denotes an N-channel field-effect transistor, so…

Larger 319 KB PDF for the 2SC4915, an NPN bipolar transistor numbered under the Japanese JIS scheme.

Small 64.5 KB PDF named 2N6764, placed in the schematic category. Only the JEDEC semiconductor code is given, with no model, brand or board details.

Second PDF copy of the Quanta AT5 motherboard schematic, revision R1A, about 1.22 MB. AT5 follows the project-code pattern of Quanta, the ODM that manufactures laptops…

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.

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

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.

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

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

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…

Reference PDF for the 2SK2714 transistor, 144 KB, filed in the schematic section. JIS naming uses 2SK for N-channel field-effect transistors, so the contents should be a…

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.

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.

The 2SK2267 named here is an N-channel FET under the Japanese JIS/EIAJ scheme, where 2SK denotes that transistor class.

The file name gives nothing beyond 2SK2233, a JIS/EIAJ designation whose 2SK prefix marks an N-channel field-effect transistor.

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…

A 96.5 KB PDF identified only as 2SK1889 and filed under schematics. Under the JIS scheme the 2SK prefix indicates an N-channel field-effect transistor, so the file most…

Datasheet-type file for the 2SK1464 N-channel field-effect transistor, 120 KB in PDF form and indexed as a schematic.

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…

Reference sheet for the 2SK937 transistor, a 79.9 KB PDF. Parts in the 2SK range are N-channel field-effect transistors under the Japanese JIS designation.

Datasheet-type PDF for the 2SK536, 60.8 KB, catalogued under schematics. Under the Japanese JIS system the 2SK designation means an N-channel FET, so the content…

Datasheet-style PDF of 31.0 KB for the 2SJ595, catalogued among schematics. JIS designations starting with 2SJ belong to P-channel field-effect transistors.

The 2SJ407 is documented in this 398 KB PDF, catalogued as a schematic though it is a component datasheet by name.

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

Component sheet for the 2SJ307, delivered as a 115 KB PDF and indexed under schematics. Only the part number is given in the name.
