Small 69.9 KB ZIP whose name points to a 128 KB image with version string DWCN20WW. The WW-suffixed format resembles Lenovo firmware versioning, and a 128 KB size…

A 169 KB PDF for the 2SD1803, placed in the schematic category but evidently a component reference sheet. No manufacturer, revision or variant is named.

PDF sheet of 38.4 KB for the 2SD2575, with an _E suffix in the file name. Filed as a schematic, it most likely holds datasheet content, because 2SD is the JIS code for…

Datasheet-type PDF of roughly 41.9 KB for the 5LN02SP, placed in the schematic category.

Component sheet for 5HP01C, a 26.8 KB PDF without any laptop, brand or board number in its name.

Optocoupler datasheet for the 4N29, with the name indicating revision 4x, supplied as a PDF of roughly 287 KB.

Compact 38 KB PDF datasheet for the 2SD2142K, an NPN transistor named in the Japanese JIS scheme, where the trailing letter marks a specific package or variant.

The 3SK219 is covered by this compact PDF of roughly 30 KB, indexed as a schematic but by its name a part datasheet.

The smallest of this group at 23.0 KB, this PDF covers the 2sk2474, a JIS-numbered N-channel FET.

Datasheet-type PDF of 419 KB named after the 2SK2314. The 2SK prefix in the Japanese JIS designation identifies an N-channel field-effect transistor, so this…

The 2SK1266 N-channel field-effect transistor is documented in this 33.9 KB PDF, indexed as a schematic.

Under the JIS semiconductor scheme the name 2SJ464 refers to a P-channel FET, and this 320 KB PDF, although indexed as a schematic, should be its datasheet.

A 110 KB PDF labelled 2SJ440 and listed under schematics. The 2SJ prefix is the Japanese JIS code for P-channel field-effect transistors, so the content is likely a…

PDF for the 2SJ306, about 94.4 KB. The name contains just the transistor type, so no device, board or revision can be stated.

A compact 27.8 KB PDF named after 2SJ164, a JIS designation identifying a P-channel FET.

Datasheet for the 2SD669 NPN transistor in a small 32 KB PDF, maker not stated in the file name.

At 464 KB, this PDF for the 2SC5264 is the largest of the related transistor files and is likely a full datasheet with characteristic curves.

The 2SC4429 is the only information carried by this 107 KB PDF name. Following Japanese JIS semiconductor numbering, 2SC stands for an NPN bipolar transistor, so the…

A 206 KB PDF named only 2SC5148, filed with schematics but describing a single part. In the Japanese JIS system the 2SC prefix denotes an NPN bipolar transistor, so the…

Component documentation for the 2SC4269 in PDF form, 108 KB in size, listed in the schematic category. Nothing beyond the part number appears in the name.

PDF part sheet for the 2SC5577, 40.7 KB, catalogued with schematics. The name gives only the part number and says nothing about the maker or revision.

At 108 KB, this PDF is labelled with the transistor type 2SC4221 and nothing else, so no board, model or revision is identified.

Covering the transistor 2SC4104, this compact 19.1 KB PDF is tagged as a schematic, but the 2SC prefix in Japanese JIS numbering identifies an NPN bipolar device, so…

Filed under schematics, this 466 KB PDF is identified by the code 2SC4839 alone. In the Japanese JIS designation system the 2SC prefix belongs to NPN bipolar…

A 102 KB PDF on the 2SC3752 transistor, an NPN device under the JIS 2SC scheme. The name contains nothing beyond the part number, so no board or model is identified; the…

For the 2SC3597 transistor, a 119 KB PDF filed as a schematic but containing component data.

Only the part number 2SC3361 appears in the name of this 129 KB PDF, so no equipment or board can be identified from it.

The 2SC3087 is the subject of this 93.1 KB PDF, listed among schematics. No maker, package or revision appears in the name.

Named for the 2SC2898, this 50 KB PDF is categorised as a schematic but should contain the datasheet of an NPN bipolar transistor, as indicated by the JIS 2SC prefix.

Small 42.8 KB PDF for the 2SC2188, carrying an _E suffix in its name and filed under schematics.

PDF of 309 KB for the 2SC1815L, an L-suffixed version of a JIS-numbered NPN bipolar transistor, filed under schematics.

The 2SB1674 named here is, under JIS conventions, a PNP bipolar transistor; this 52.6 KB PDF, despite its schematic category, is therefore most likely the datasheet.

Small PDF document for the 2SA1524, filed under schematics but by its name a component data sheet for a discrete transistor.

Small PDF of 42.0 KB covering the 2SB1030, with an _E suffix that may mark a document edition, though the name does not say.

Part documentation for the 2SA1415 transistor, delivered as a 116 KB PDF and indexed as a schematic.

Datasheet PDF of only 13.5 KB for the 2SA684 transistor, marked UTC, which indicates the Unisonic Technologies edition of this part.

A 43.6 KB PDF on the 2SA1209, filed under schematics but named solely by the part code, so most likely a short datasheet.

Datasheet covering the 2SA1806, stored as a 44.6 KB PDF whose name carries an E suffix, probably indicating an edition or language version of the document.
