The 2SD1907 is covered by this 165 KB PDF, which is catalogued as a schematic but by name is a component datasheet.

The 2SK545 is covered by this 80.4 KB PDF, filed as a schematic but most likely a datasheet because 2SK numbers identify N-channel field-effect transistors in the…

The name of this 97.3 KB PDF gives nothing beyond 2SJ277, a JIS-style designation in which 2SJ marks a P-channel FET.

Only the part number 2SJ275 appears in the name of this 97.0 KB PDF. That code follows Japanese JIS numbering, where 2SJ indicates a P-channel field-effect transistor…

The 2SC4121 part number is the whole name of this 89.5 KB PDF; although typed as a schematic, it should be the datasheet for that NPN bipolar transistor, as the Japanese…

PDF, 52.3 KB, documenting the 2SA1177, a PNP bipolar transistor in the JIS 2SA numbering scheme.

A 140 KB PDF named after the semiconductor 2SJ563, listed in the index under schematics.

A compact 44.5 KB PDF labelled 2SJ520 and catalogued as a schematic. Because 2SJ is the JIS prefix for P-channel FETs, the document is best treated as a short datasheet…

Filed as a schematic, this 93.5 KB PDF is identified solely by 2SJ274. The Japanese JIS 2SJ prefix stands for a P-channel field-effect transistor, so the content is most…

Named after the JIS part number 2SJ267, this 91.8 KB PDF most likely documents a P-channel field-effect transistor, since the 2SJ prefix denotes that device class.

The 2SA1734 is the subject of this 183 KB PDF, which carries only the component number in its name.

Schematic for board V336, revision marked 20 and probably meaning 2.0, as a decrypted PDF of about 1.04 MB.

Circuit diagram set for the Compal LA-5481P laptop mainboard, revision R0.2, delivered as a 953 KB RAR file.

The 2SD2285 is documented in this 128 KB PDF. Its JIS part number, with the 2SD prefix, places it among NPN transistors intended for low-frequency circuits such as…

Covering the 2SK2910 transistor, this 150 KB PDF is listed in the schematic category but reads from its name as a component datasheet.

PDF of 37.3 KB named after the 2SC5406 and listed as a schematic, though it is almost certainly a component datasheet.

Compact 49.5 KB PDF for the 2SC3354, with an _E suffix in the name that may indicate an English-language edition, though the name does not confirm it.

A compact PDF of 48 KB filed under schematics, named after the part 2PB1219A with a trailing 3 that probably marks a document issue.

PDF of 25.8 KB carrying only the code 2pg302 in its name and filed under schematics. No laptop model, board number or manufacturer is stated, so the content cannot be…

PDF of 47.7 KB named 2PD602A, apparently issue 4 of the document. The name identifies a part rather than a product or board, which points to a discrete semiconductor…

PDF of 168 KB filed as a schematic and named 2N2219A, a designation in the JEDEC 2N numbering used for discrete semiconductors.
