PDF reference of 182 KB for the 2SA1431 semiconductor. Following JIS rules, 2SA part numbers are PNP transistors, formally classed for high-frequency use.

Specifications for the 2SA1963 transistor are expected in this 160 KB PDF, which the index labels a schematic.

Component PDF for the 2SA1248, 47.6 KB, which the index lists as a schematic. Only the part code appears in the name; under the JIS system, 2SA designates a PNP…

Datasheet PDF, 40.9 KB, for the 2SA1128 transistor, with an _E suffix that often denotes an English edition of Japanese documentation, though the name does not confirm…

Datasheet PDF of 190 KB for the 2SA1761, filed under the schematic type. In the JIS scheme the 2SA prefix denotes a PNP bipolar transistor, and the name gives nothing…

Reference sheet in PDF form (150 KB) for the registered semiconductor number 2N6804, catalogued under schematics.

PDF reference sheet of 59.1 KB for the 2N3702, a transistor from the JEDEC 2N numbering series, catalogued under schematics.

A 148 KB PDF named 27lc512, filed under schematics but most likely a datasheet for a low-voltage 27-series EPROM, given how the part number is built.

Parallel flash datasheet, 174 KB PDF named 29F080 and filed under schematics. The 29F080 designation is commonly used for 8 Mbit parallel NOR flash memory; the name…

PDF copy of USB Complete, third edition, an 8.27 MB reference book on the Universal Serial Bus rather than a board schematic.

Repair guide in PDF form for the ASUS UX305FA ultrabook, catalogued under schematics at 1.2 MB.

Quanta UM3B schematic in PDF form, about 2.9 MB, with no brand, model, board number or revision in the name.

Component data for the 2SK3448, filed under schematics but in practice a short datasheet-style PDF of 27.6 KB.

The 2SK2294 is the subject of this 140 KB PDF, catalogued as a schematic but in substance most likely a datasheet, as 2SK marks N-channel field-effect transistors under…

Datasheet in PDF form for the 2SK2058, a part number in the Japanese JIS 2SK series, which designates N-channel field-effect transistors.

34.2 KB PDF for the 2SK1255 N-channel MOSFET, listed under schematics in the index although it is a single-component sheet.

Larger 225 KB PDF for the 2SK436, indexed as a schematic yet most likely a full datasheet with graphs and package dimensions, since 2SK numbers denote N-channel FETs…

Compact 29.9 KB PDF titled with the part number 2sk301 only. The 2SK prefix under JIS rules marks an N-channel FET, so this is best treated as a component data sheet…

Part documentation for the 2SC5266A in PDF form, 182 KB, listed among schematics. JIS numbering makes 2SC an NPN bipolar transistor, while the A suffix generally…

Part-number document for the 2SC5173, stored as a 231 KB PDF under the schematic category.

The 2SC4249 transistor is the subject of this 263 KB PDF, filed under schematics. The name carries the part number alone, so maker and revision are not stated.

Part number 2SC5690 is all the name reveals about this 28.8 KB PDF, filed under schematics.

Compact 34.8 KB PDF for the 2SC5305 transistor, a part number in the JIS 2SC series used for NPN bipolar devices.

An 88.2 KB PDF carrying only the designation 2SC3402, catalogued as a schematic but almost certainly a single-part reference sheet.

Reference sheet for the 2SA1519 PNP transistor in PDF form, about 30.2 KB, categorised here as a schematic.
