RAR package for the HP Pavilion DV5 laptop built on the Quanta QT6 board, revision 1A. Quanta is the ODM behind this design, and its documents normally name boards with…

Schematic PDF for the IBM ThinkPad T61 laptop; the file name gives no board number or revision, so verify the planar variant against the drawing title blocks.

This PDF of about 124 KB covers the 2SD2114 transistor with a KS suffix; the suffix is not explained by the name and may denote a gain class or package variant.

The name offers nothing beyond the 2SD2500 part number, and the 250 KB PDF is almost certainly that transistor's datasheet.

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.

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

Part reference for the 2SK2782, delivered as a 419 KB PDF under the schematic label. The 2SK prefix follows Japanese JIS numbering for N-channel field-effect…

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…

PDF reference, 115 KB, for the 2SK1924 N-channel field-effect transistor; the 2SK prefix places it in the Japanese JIS transistor registry.

Reference document for the 2SK1436 transistor, supplied as a 105 KB PDF and listed under schematics.

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

Part documentation for the 2SJ337 in a 98.2 KB PDF. The file name names only this semiconductor, nothing about a device.

A 247 KB PDF titled only with the part number 2SC4667, catalogued here as a schematic. The 2SC prefix is the JIS code for an NPN transistor intended for high-frequency…

Component document for the 2SC5201 part number, catalogued as a schematic but almost certainly a semiconductor datasheet given the name and small 115 KB PDF size.

Reference PDF for the 2SC4224, at 97.3 KB, catalogued as a schematic although the name is just a semiconductor part number.

Named 2SC5569 and weighing 50.3 KB, this PDF sits in the schematic category but refers only to a transistor part number.

The 2SC3916 NPN transistor is the subject of this 30.8 KB PDF. Since the name is only a JIS part number, where 2SC stands for an NPN bipolar device, it is best treated…

Specification PDF, 30.2 KB, for the 2SC3913 transistor. JIS part numbering assigns the 2SC prefix to NPN bipolar devices, so the document is most likely a datasheet…

Listed under schematics, this 93.2 KB PDF documents the 2SC3685, an NPN bipolar transistor by JIS designation.

Specification document for the 2SC3515 transistor, a 225 KB PDF placed in the schematic category.

Data sheet style PDF, 103 KB, for the 2SC3149 NPN bipolar transistor named under the JIS 2SC scheme.

Datasheet PDF of 248 KB for the 2SC3138, an NPN bipolar transistor going by its Japanese JIS 2SC prefix.

Part reference for the 2SC1518 in a 51.5 KB PDF carrying an _E suffix, filed under schematics.

Data document for the 2SB1556 bipolar transistor, 177 KB in PDF, filed under schematics.

Filed as a schematic, this 40.6 KB PDF takes its name from the 2SB1207 part number, followed by an _E suffix, and most likely contains the transistor datasheet.

PDF of 42.2 KB named 2SA1982 with an _E suffix, which commonly marks an English-language edition, though the name does not confirm this.

Datasheet PDF for the 2N4031 part number, 52.3 KB in size, placed in the schematic category of the index.

Reference PDF for the 2N3906, 61.0 KB, a widely encountered JEDEC part number that turns up in many consumer and hobby circuits.

Datasheet for the 1N6263, a small-signal Schottky diode, stored as a compact 44.5 KB PDF and listed under schematics.

Named simply 1N821, this 34.4 KB PDF follows JEDEC 1N diode numbering and is most likely a single-part datasheet, not a circuit diagram, even though it sits in the…

The file name gives just the code 122NQ030 for this 97 KB PDF in the schematic category; no laptop model, board number or revision is mentioned.

Catalogued as a schematic, this 200 KB PDF is named 20CJQ030 and says nothing about a device, board or revision.
