Maxim MAX1540 datasheet, an 838 KB PDF identified only by its part number. Read the opening page for the device function and electrical limits.

Part datasheet in PDF for the MJE13007F, a high-voltage NPN switching transistor. The F suffix usually denotes an isolated fully plastic package, though the name states…

A 53.4 KB PDF covering the 2SD2614 transistor, catalogued as a schematic although the name points to a single-part datasheet.

Compact 29.7 KB PDF for the 2SD2649, placed in the schematic section though the name indicates a component datasheet.

Reference PDF of 40.9 KB for the 2SD1819A, with an E tag in the name that probably denotes an English-language edition, filed under schematics.

The 2SD1908 transistor is documented in this 85.8 KB PDF, which the index files as a schematic, although a JIS part number like this normally indicates a datasheet.

A 68.3 KB PDF bearing the name 2SD2324, a Japanese JIS designation for an NPN transistor, since 2SD marks NPN low-frequency devices.

A 116 KB PDF for the 2SK2731 bearing a 1-5 suffix that the name does not explain, perhaps an edition marker.

Compact 23.1 KB PDF named only with the part number 2SK2277. Because 2SK is the JIS prefix for N-channel FETs, the schematic category here most likely holds a short…

The 2SK445 part number is all the name provides for this 89.6 KB PDF, filed as a schematic but best treated as a datasheet, as 2SK numbers designate N-channel…

Part reference 2SJ508 is all the name provides for this 136 KB PDF, categorised as a schematic.

Listed under schematics, this 94.5 KB PDF carries only the designation 2SJ276. Under the JIS system the 2SJ prefix belongs to P-channel FETs, so the file is almost…

The 90.8 KB PDF is named only 2SJ273, a part number in the JIS series used for P-channel FETs.

Listed as a schematic, this 246 KB PDF carries the name 2SJ201, a JIS part number for a P-channel FET, so it is best treated as a component datasheet.

PDF document for the 2SD1205 transistor, listed in the index as a schematic but almost certainly a part datasheet; the trailing _E in the name is a suffix whose meaning…

Here is a compact 94.6 KB PDF named for the transistor type 2SC4660. The name points to the part itself rather than any board or appliance.

At 214 KB, this PDF named 2SC4118 is filed as a schematic but is most plausibly a fuller datasheet for that part, likely with characteristic curves.

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.

Small 84.1 KB PDF whose name, 2SC3792, is a bare transistor designation; it sits in the schematic category, yet the Japanese 2SC prefix points to an NPN bipolar device…

2SC3598 datasheet in a 119 KB PDF, catalogued in the schematic group. Only the part number appears in the name; under Japanese JIS numbering the 2SC prefix identifies an…

Named after the 2SC1383, this 51.4 KB PDF is listed as a schematic, yet the JIS prefix 2SC denotes an NPN bipolar transistor, so expect a part datasheet.

Listed among schematics, this 60.7 KB PDF refers to the 2SC1047, which under JIS numbering is an NPN bipolar transistor; the content is therefore most likely a part…

Component datasheet for the 2sb1580, 64.2 KB in PDF and indexed as a schematic. The 2SB prefix comes from the JIS standard and indicates a PNP bipolar transistor for…

Datasheet for the 2sb1566 PNP bipolar transistor in a 37.5 KB PDF. The 2SB label, per the JIS convention, means a PNP device for low-frequency circuits; the file name…

Component reference for the 2SA1521 transistor, stored as a 30.2 KB PDF and filed under the schematic category.

The 2SA1518 is the subject of this 30.2 KB PDF, which the index files as a schematic although the name suggests a component data sheet.

PDF of 41.0 KB for the 2SB873, with an _E suffix whose meaning the name does not explain.

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

Short 31.2 KB PDF for the 2SA1864, a PNP bipolar transistor in the Japanese JIS 2SA family.

Small 81.5 KB PDF named after the 2SA1724 part number and filed under schematics. Nothing else in the name identifies a product or circuit board.

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…

PDF reference of 51.6 KB named 2N1613, placed in the schematic category. The 2N prefix follows the JEDEC numbering used for discrete semiconductors, so the content is…

A 272 KB PDF for part number 2N5555, with a rev0x tag in the name that seems to mark a document revision, though its exact meaning is not stated.

The 1SS190 is the only information in this file name, apart from an underscore. The 68.1 KB PDF sits under the schematic category.

Part number 1SS345 is the only information in this 58.3 KB PDF name, so no laptop, board or revision is identified.

Labelled 1SS268, this 126 KB PDF appears to be a datasheet for a single component even though the index lists it as a schematic.
