Reference sheet for the 2N4264, saved as a 264 KB PDF and carrying an RE tag in the file name that is not explained further.

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

Indexed as a schematic, this 109 KB PDF is titled 2SD1621, a transistor part number, so treat it as a datasheet rather than a circuit diagram.

Part document for the 2sk2575, 35.2 KB in PDF format and catalogued as a schematic. The 2SK prefix in JIS nomenclature marks an N-channel field-effect transistor; the…

Small 35.2 KB PDF identified only by the part number 2SK665, a designation from the Japanese 2SK family of N-channel FETs, so the content is most likely a component…

Brief 24.7 KB PDF for the 2SJ0398, written with a leading zero in the name, which most likely refers to the 2SJ398 P-channel FET in JIS numbering.

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

A 29.5 KB PDF referencing the 2SC5792 transistor, an NPN device in the JIS-registered 2SC range.

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…

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

The 2SC2073A, an A-suffixed variant of a JIS-numbered part, is covered by this 154 KB PDF listed as a schematic.

A 214 KB PDF for the 2SA1429 part, catalogued as a schematic though most likely a data sheet.

At 206 KB, this PDF is one of the larger files in the group and covers the 2SA1408, a component numbered under the Japanese JIS system where 2SA indicates a…

PDF document for the 2SA1380, a part number that follows the Japanese JIS scheme, where the 2SA prefix marks a PNP transistor intended for high-frequency use.

Component documentation for the 2SA1892, supplied as a 225 KB PDF. Under Japanese JIS naming, 2SA marks a PNP bipolar transistor, so despite being classed as a schematic…

Only the JEDEC part number 2N5460 is given for this 115 KB PDF, listed as a schematic. The same size as the 2N5461 and 2N5462 files suggests a shared family datasheet…

A compact 36.0 KB PDF for the 2SD1949 transistor. The 2SD prefix in the JIS system designates an NPN device for low-frequency circuits, so the content is expected to be…

Component datasheet for the 2SB1434 transistor, filed under schematics but in practice a part reference rather than a board diagram.

Schematic for the 2012 MacBook Air 13-inch A1466, logic board 820-3209-A, packed as a 2.78 MB RAR containing a PDF.
