PDF of 173 KB for the 2SC4707, sorted into the schematic category. Because 2SC is the JIS/JEITA designation for NPN bipolar transistors, expect a component datasheet…

Filed under schematics, this 138 KB PDF is named after the 2SK2463, a JIS-style part number, so it is most likely a component datasheet rather than a board drawing.

PDF datasheet of 287 KB for the 2SK2009, an N-channel field-effect transistor under the Japanese 2SK designation.

A 39.2 KB PDF for the 2SC3956 transistor, indexed as a schematic but by its name a datasheet for a JIS-designated NPN bipolar device.

Component reference for the 2SB1386, a 155 KB PDF that likely holds full electrical tables, though the name states nothing beyond the part number.

Indexed as a schematic, this 72.3 KB PDF relates to the 2SB888, likely as its data sheet.

Compact 80.7 KB PDF for the 189NQ135, a single Schottky rectifier designation in the NQ range; the 135 suffix most likely means a 135 V reverse rating.

The 2SK3121 is covered by this 126 KB PDF, which the index lists as a schematic although it serves as a part datasheet.

PDF of 56.2 KB named 2SD1391, a JIS designation for an NPN low-frequency bipolar transistor, and presumably its datasheet although indexed under schematics.

Data reference for the 1SV239, a 70.1 KB PDF whose trailing underscore carries no meaning. The index files it as a schematic.

Part-number document for the 2SC5173, stored as a 231 KB PDF under the schematic category.

Datasheet in PDF format for the 2SC5583, 46.0 KB in size. The file name states the part number and nothing else.

PDF of 41.0 KB for the 2SC3904 transistor, with an _E suffix in the name whose meaning is not stated, possibly an edition or language marker.

This 41.1 KB PDF bears the part number 2SA1536 and, although indexed as a schematic, is best treated as the datasheet for a JIS-registered transistor.

PDF datasheet material for the 1SS397, sized at 77.7 KB and indexed under the schematic type.

Diagram of a 2.1 preamplifier joined to an audio power amplifier, taken from a YouTube project; the doubled pdf extension is just a naming slip.

At 351 KB, the largest of this set of 2SC sheets, this PDF covers the 2SC3268 and is catalogued as a schematic while most likely holding a transistor datasheet.

This 145 KB PDF carries the 2SD1722 part number and nothing more, so it is best treated as that transistor's datasheet.

PDF reference, 105 KB, for the 2SK1813 transistor. In the Japanese JIS scheme, 2SK designates an N-channel field-effect transistor, so this is probably its datasheet.

Component documentation for the 2SK1033, a 34.4 KB PDF file. The 2SK series covers N-channel field-effect transistors in the Japanese designation system, and a…

PDF of 42.8 KB for part 2SJ585LS, listed under schematics. JIS semiconductor coding assigns 2SJ to P-channel FETs, so this is most probably a datasheet with ratings…

A 137 KB PDF on the 2SA1225, named only with the part number; despite the schematic category it is most likely the manufacturer datasheet.

Component documentation for the 2SK1904, provided as a 95.2 KB PDF and filed as a schematic.

Datasheet-like PDF, 42.5 KB, for the 2SJ583LS and filed as a schematic. Japanese JIS designations starting with 2SJ belong to P-channel FETs, and the LS suffix points to…

Datasheet-style PDF for the 2SD1302, 46.0 KB, listed in the schematic category. The 2SD prefix follows the Japanese JIS designation for NPN bipolar transistors in…

Datasheet in PDF format for the 2SA1579 transistor, 36.6 KB. Only the part number is given in the name.

A 144 KB PDF filed under schematics for the 220CNQ030, a designation that matches the CNQ family of high-current Schottky rectifier modules.

Part documentation for the 2SK2987, provided as a 426 KB PDF. The 2SK designation follows the Japanese JIS standard for N-channel field-effect transistors, so the file…

Reference PDF for the 2SK2122, about 35 KB and catalogued under schematics, although the plain part-number name implies a datasheet.

A 120 KB PDF for the 2SK2083, indexed under schematics but most probably the component datasheet.

Specification sheet for the 2SC5276, a 136 KB PDF. The 2SC designation follows the Japanese JIS scheme for NPN bipolar transistors, so the document is probably the…

Short 34.8 KB datasheet-style PDF for the 2sk2576, an N-channel FET under the Japanese JIS 2SK designation.

Small 43.1 KB PDF for the 2SJ400, likely a short datasheet despite being indexed as a schematic.

Lenovo all-in-one A560-27IOB document for the IB560SL2 mainboard, LCFC project NM-D661, labelled boardview but stored as a 332 KB PDF.

Titled in lowercase as 2sd1414, this 62.9 KB PDF is catalogued as a schematic, though a lone part number indicates a transistor datasheet.

Named after the 2SK210, this 362 KB PDF sits in the schematic category but most probably contains the datasheet for that JIS N-channel FET.

Component document for the 2SC2669, delivered as a 473 KB PDF and filed under schematics. The 2SC prefix is the JIS designation for NPN bipolar transistors.

PDF datasheet of roughly 194 KB for the 2SA2065 transistor, catalogued among schematics.
