Reference sheet for the 2SJ418 P-channel FET, supplied as a 128 KB PDF and indexed as a schematic.

Bearing only the part code 2SJ264, this 101 KB PDF relates to a P-channel FET, as the JIS 2SJ prefix designates that transistor type.

Only the transistor number 2SJ259 appears in the name of this 99.0 KB PDF. JIS coding uses 2SJ for P-channel FETs, which suggests a datasheet even though the file is…

Datasheet-style PDF covering the 2SD1199, catalogued under schematics, with an _E suffix in the name that the file does not explain.

Compact 63.0 KB PDF for the 2SC5585, a JIS-numbered transistor, indexed with schematics. The name provides the part number alone, without maker or revision.

The 2SC4071 is the subject of this 47.7 KB PDF, which sits in the schematic category although the name suggests a single-component datasheet.

Part documentation for the 2SC5026 in PDF form, 41.3 KB, its name ending in an _E suffix.

PDF document for the 2SC4853, a part number following the Japanese JIS scheme in which the 2SC prefix marks an NPN bipolar transistor.

Part number 2SC3805 is the only information in this 184 KB PDF name, and although it is listed as a schematic, the 2SC prefix under Japanese JIS numbering identifies an…

The name of this 176 KB PDF consists only of 2SC3790, a JIS-style part number in which 2SC denotes an NPN transistor.

An 82 KB PDF for the 2SC3784, part of the JIS 2SC family of NPN transistors. It is listed as a schematic, but the file name points to a single component, so it is most…

Reference sheet for the 2SC5363 transistor, delivered as a compact 40.7 KB PDF and listed among schematics.

Specification sheet for the 2SC3600 transistor in PDF form, 136 KB, listed under schematics.

Compact 91.1 KB PDF datasheet for the 2SC3595 transistor, listed in the schematic category.

Part data for the 2SC3152 NPN transistor, stored as a 103 KB PDF in the schematic section.

A 45.3 KB PDF titled with the JIS transistor number 2SC2909, filed under the schematic category.

Component documentation for the 2SA1591, an 89.4 KB PDF. Only the part number appears in the name; no revision or manufacturer is given.

Filed as a schematic, the 51.8 KB PDF for the 2SA1534 carries an _E suffix in its name whose meaning is not stated; the content is most likely the datasheet for this JIS…

The 2SA1869 is covered by this 174 KB PDF, a PNP bipolar transistor in the Japanese JIS 2SA series.

Small PDF listed as a schematic, though the name 2SA777 with suffix E reads like a discrete semiconductor part number in the Japanese 2SA style rather than a board…

Filed as a schematic, this 133 KB PDF is named 59C11-2, a code that gives no laptop model, brand or clear board revision.

A 163 KB PDF catalogued as a schematic, though the name points to the 28LV256, a 256 Kbit low-voltage parallel EEPROM, so it is most likely a datasheet.

PDF of about 140 KB covering two groups of the 24Cxx serial EEPROM family, labelled XX1 and XX2 in the name, likely corresponding to different density ranges or data…
