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.

Indexed as a schematic, this 79.2 KB PDF is named 2SC4400 and should be the reference datasheet for that NPN bipolar transistor.

Listed under schematics but named only after a part number, this 91.6 KB PDF most likely holds the datasheet for the 2SC4188 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…

A PDF document for the 2SC4884, filed under schematics but by its name a component datasheet rather than a board diagram.

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

A brief 48.3 KB PDF on the 2SC3504, catalogued as a schematic but containing transistor data.

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.

Filed under schematics, this compact 39.7 KB PDF is named after the 2SB976 part number, a Japanese JIS-style designation where the 2SB prefix marks a PNP transistor…

PDF of 61.5 KB for the 2SA1870, with a 1-2 tag in the name. That tag may indicate one part of a split document or a revision, but the name does not say which.

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

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

Power supply schematic for a Toshiba TCL L32S4900S television, covering the PLE55-1A power board, revision 1.1, as a 4.53 MB PDF; fonte is Portuguese for power supply.

Audio Pro Ace Bass B4-200 subwoofer service manual, going by the AceBassB4_200, sub and sm tokens.

Audio Pro Ace Bass B2-40 subwoofer service manual in PDF form, about 1.96 MB, as indicated by the sub and sm tags.

Third edition of a beginner's guide to reading schematics, a 3.33 MB PDF. It is an educational text rather than a diagram for a specific device.

Compact 29.5 KB PDF for the 2SC3678, catalogued under schematics, with only the part number in the name.

Combined data document for the BD135, BD137 and BD139 transistors, filed under schematics, 51.0 KB in PDF form.

Reference sheet for the 2SD2607 component, delivered as a 51.7 KB PDF and filed under schematics. No brand or variant appears in the name beyond the part number itself.

Component document in PDF for the 2SK2555, filed under schematics although the part number points to a discrete semiconductor rather than a board.

The part number 2SJ466 is the only detail in the name of this 40.0 KB PDF, tagged as a schematic.

Reference PDF of 218 KB for the 2SC4754, indexed as a schematic but named after a single semiconductor part.

A small 51.5 KB PDF carrying the part number 2sc5147, catalogued as a schematic but almost certainly a component datasheet for that NPN transistor.

Catalogued as a schematic, this 240 KB PDF carries only the part number 2SC4200 in its name, which points to a component datasheet rather than a board diagram.

Listed as a schematic, this 28.7 KB PDF is named only after the part number 2SC5681, which in the Japanese JIS scheme marks an NPN bipolar transistor, so it is most…

A 64.4 KB PDF for the 2SA1906, with a 1-2 suffix in the name that may indicate the first of two pages or parts; the exact meaning is not stated.

Datasheet-style PDF of 101 KB for the 2SA1731, indexed under schematics but named only by part number with no device or board information.

Component document in PDF form, 47 KB, named 2PA1774 with a suffix 2 that likely denotes the sheet issue.

Component sheet in PDF format, 47.7 KB, named for 2PC4081, probably revision 4 of the document.

RAR archive of about 20 MB described in Portuguese as schematics with voltages in PDF format; no brand or model is named, so the contents must be checked after…

PDF schematic of a 150 W amplifier, marked as a new version and converted from another file format, judging by the name.

Reference PDF for the BD136, BD138 and BD140 transistor series, catalogued as a schematic but in practice a component datasheet of 51.2 KB.

Component document for the 2SD1684, filed under schematics but named after a Japanese JIS part number rather than a board.

Small PDF of about 30 KB filed as a schematic for the 3SK241 part number. The 3SK prefix is the Japanese JIS designation for four-lead field-effect transistors…

A PDF of 119 KB filed under schematics, though its name is simply the Japanese part number 2SC4364, which points to a component datasheet rather than a board diagram.
