A 41.6 KB PDF for the 2SC3114, an NPN bipolar transistor under the JIS 2SC designation.

A PDF of about 318 KB covering part 2SC3098, likely the datasheet for that device even though it is catalogued as a schematic.

Indexed as a schematic, this 96.7 KB PDF is named for the 2SC3086 and most likely holds that transistor's datasheet.

The 2SC3040 appears in the name of this 107 KB PDF, which is indexed among schematics and probably holds that part's datasheet.

Filed under schematics, this 99.9 KB PDF is named for the 2SC3038 transistor and probably contains its datasheet.

Document for the 2SC2778 transistor, a 60.1 KB PDF whose name ends with _E. The suffix may indicate an English-language edition, but the name does not confirm it.

Named for the 2SC2555, this 186 KB PDF is filed under schematics but is most likely the component's datasheet.

The 2SC2230 is the subject of this 202 KB PDF, indexed among schematics yet named only by a transistor part number.

Covering the plain 2SC1627 without suffix, this 211 KB PDF sits in the schematic category but names only a part number.

The 2SA1362 gets this 201 KB PDF, which carries only the part number and is therefore most likely the manufacturer datasheet rather than a board schematic.

Datasheet for the 2N3055, filed here under schematics as a 39.8 KB PDF. The 2N3055 is a classic NPN silicon power transistor, usually in a TO-3 metal can, found in…

Component documentation for the 2SD2257 transistor, in PDF form at 180 KB. Although the index lists it as a schematic, the file name points to a single discrete part…

Datasheet for the 2SD612K transistor, a 303 KB PDF listed in the schematic section. The K at the end belongs to the type number and indicates a variant of the 2SD612…

PDF datasheet, 40.9 KB, for the 2SD2240 transistor, filed under schematics in this index. An _E suffix in the name is an edition marker for the document only.

Covering the 2SD2645, this 29.3 KB PDF sits in the schematic index although the name suggests a component datasheet.

Datasheet-type PDF, 30.8 KB, for the 2SD2627LS, catalogued as a schematic. The LS suffix is part of the type designation and likely refers to a specific variant or…

PDF of 75.0 KB covering the 2SD2176 part. Though listed as a schematic, a file named after a single JIS transistor number is most likely a datasheet, and the 2SD prefix…

Single-part PDF of 47.0 KB for the 2SD2583, listed as a schematic but most probably a datasheet.

Datasheet-style document for the 2SD2581 transistor, saved as a 43.7 KB PDF and filed in the schematic category.

Compact 42.8 KB PDF for the 2SD2537, listed as a schematic though the name points to a single-component datasheet.

Part datasheet for the 2SD1782K, an NPN transistor named under the Japanese JIS scheme, with the K suffix indicating a particular variant or package.

This PDF of about 124 KB covers the 2SD2114 transistor with a KS suffix; the suffix is not explained by the name and may denote a gain class or package variant.

The 2SD2079 PDF, 219 KB in size, is indexed as a schematic yet corresponds to a single discrete component.

The name offers nothing beyond the 2SD2500 part number, and the 250 KB PDF is almost certainly that transistor's datasheet.

The 2SD1683 is the subject of this 146 KB PDF, which is catalogued as a schematic although the name is a transistor part number.

Part reference for the 2SD1669, supplied as a 107 KB PDF and filed in the schematic section.

Transistor documentation for the 2SD1667, 136 KB in PDF format. Nothing beyond the part number appears in the name.

PDF of 119 KB for the 2SD1664, written in lowercase in the original name and filed as a schematic.

At 198 KB, the PDF for the 2SD1658 is one of the larger sheets in this group, though it still names only the part.

Datasheet PDF, 60 KB, for the 2SD1650, with the name given in lowercase and filed under schematics.

The 2SD1628 is covered in this 88.3 KB PDF, catalogued with schematics though it relates to a single transistor.

Indexed as a schematic, this 109 KB PDF is titled 2SD1621, a transistor part number, so treat it as a datasheet rather than a circuit diagram.

Part number 2SD1424 with an unexplained _E suffix names this 41.4 KB PDF, indexed among schematics but most likely a datasheet for the transistor.

Component documentation for the 2SD1881 transistor, supplied as a 90.6 KB PDF and catalogued as a schematic, though a part number like this normally points to a…

PDF covering the 2SD1880, about 88.9 KB, listed as a schematic but named after a single semiconductor part.

Part number 2SD2459 names this 41.2 KB PDF, followed by an unexplained E tag; it is catalogued as a schematic.

Largest in this set at 269 KB, the PDF 2SD2414 is catalogued as a schematic, yet its 2SD prefix marks an NPN bipolar transistor under the Japanese JIS scheme.

Catalogued as a schematic, the 40.9 KB PDF 2SD2413 with an E tag relates, by the JIS 2SD prefix, to an NPN bipolar transistor rather than a complete board.

PDF document for the 2SD1995 semiconductor, catalogued under schematics but by its name a component datasheet.
