CAD-format boardview for Compal's LA-N381P, revision 1.0, zipped at 127 KB. The .cad layout gives component placement and net connectivity, so you can click a part and…

PDF for the complementary TIP3055 NPN and TIP2955 PNP power transistors, 50.1 KB, indexed under schematics.

A 29.2 KB PDF documenting the 2SD2639 part, catalogued as a schematic. Nothing beyond the type number is stated in the name.

Component reference for the 2SD2635, a 35.2 KB PDF listed among schematics. The file name offers only the part number, with no manufacturer or revision given.

Part datasheet for 5HP01SP, a 27.5 KB PDF. The name carries no model, brand or board number, only the device code with an SP suffix that likely identifies its package.

For the 2SD2098 transistor, this 159 KB PDF is categorised as a schematic but follows the usual naming of a part datasheet.

Datasheet-style PDF for the 3LP02N, about 41.5 KB and listed as a schematic. No device, brand or board details appear in the name beyond the part code itself.

Stored as a 190 KB PDF, this document is named after the 2SD1936, a JIS-registered NPN transistor.

File name 2sk198 is a JIS semiconductor number, so this 31.8 KB PDF, though catalogued as a schematic, is best treated as a brief component datasheet.

The file, a 28.4 KB PDF, is named 2SK3485 and catalogued as a schematic; the name is a JIS semiconductor number, so treat it as a short datasheet.

Part documentation for the 2SK2914 in PDF form, 396 KB, placed in the schematic section of the index.

For the 2SK2744 this 177 KB PDF provides component-level reference material, although the index lists it among schematics.

Reference sheet for the 2SK2599 in a 418 KB PDF, placed in the schematic section although the name holds nothing but the part number.

PDF reference for the 2SK2339 transistor, 35.9 KB, catalogued under the schematic type.

Component documentation in PDF format, 32.4 KB, for the 2SK2326. The 2SK prefix follows the JIS registration scheme and signifies an N-channel FET, so despite the…

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

Short PDF of 23.2 KB named for the 2SK2324 part. In JIS nomenclature 2SK denotes an N-channel FET, so this schematic-labelled file is presumably a brief datasheet.

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.

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

Short 37.3 KB PDF for the 2SK544, a part number belonging to the JIS 2SK series of N-channel FETs; although indexed as a schematic, it should be a component datasheet.

The 2SJ511 named in this 417 KB PDF is a JIS-coded semiconductor, the 2SJ prefix signalling a P-channel field-effect transistor.

Small 43.1 KB PDF for the 2SJ400, likely a short datasheet despite being indexed as a schematic.

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

Catalogued as a schematic, this 88.5 KB PDF is named only 2SJ230, a JIS code in which the 2SJ prefix identifies a P-channel field-effect transistor.

Small 89.2 KB PDF labelled 2SJ191, a JIS designation that marks a P-channel FET, so the file is presumably that part's datasheet rather than a board schematic.
