Named simply 2SC4984, this 48.8 KB PDF is catalogued as a schematic yet points to a discrete semiconductor.

Single-part reference for the 2SC4864 in a 118 KB PDF, catalogued as a schematic. Apart from the part number, the name gives no information.

Part-number document for the 2SC3917, delivered as a 30.8 KB PDF. The 2SC prefix follows the JIS system for NPN bipolar transistors, so the content should be a datasheet…

A 53.1 KB PDF referencing the 2SC3902, an NPN bipolar transistor under JIS numbering, where 2SC marks that device class.

Labelled 2SC4835 with an _E suffix, this 41.5 KB PDF is filed as a schematic but refers to a JIS-numbered NPN transistor, indicated by the 2SC prefix.

Transistor datasheet for the 2SC3474, supplied as a 303 KB PDF and filed under schematics.

A small PDF filed as a schematic, though the name is simply the part number 2SC3468, which follows the Japanese JIS semiconductor scheme where the 2SC prefix marks an…

Part number 2SC3401 is the only information in the name of this 87.3 KB PDF, so no device or board is identified.

Covering the 2SC5353, this 208 KB PDF sits in the schematic category but, judging by the name, documents a single transistor.

A 97.4 KB PDF for the 2SC3151, an NPN bipolar transistor according to its JIS 2SC designation.

The 2SC3116 NPN transistor is described in this 47.6 KB PDF, placed in the schematic category.

Reference document for the 2SC3112 transistor, supplied as a 257 KB PDF and filed under schematics. The name holds only the part number.

The 2SC3099 is the only detail this 318 KB PDF name gives, and the file is indexed as a schematic, although it is probably a datasheet.

Small 42 KB PDF for the 2SC3077, filed as a schematic. The trailing _E in the name is not explained by the file name itself.

Catalogued as a schematic, this 190 KB PDF is named after the 2SC2999, a part number in the Japanese JIS scheme where the 2SC prefix marks an NPN bipolar transistor.

A 508 KB PDF filed under schematics, named only with the JIS part number 2SC2996. The 2SC prefix identifies an NPN bipolar transistor, so the document is probably a…

Indexed as a schematic, this 187 KB PDF is named after the 2SC2880, which the JIS 2SC prefix identifies as an NPN bipolar transistor.

A 186 KB PDF identified by the part number 2SC2873 and classed as a schematic. Under the JIS standard the 2SC prefix means an NPN bipolar transistor, so this is most…

Named 2SC2859, this 192 KB PDF is indexed among schematics but probably holds the datasheet of a JIS-numbered NPN bipolar transistor, as the 2SC prefix suggests.

Reference document for the 2SC1815, a 310 KB PDF classed as a schematic. In JIS numbering the 2SC prefix denotes an NPN bipolar transistor, and the file is most likely…

Datasheet-style PDF of 170 KB for the 2SC1627A, the A-suffixed variant of a JIS-numbered NPN bipolar transistor, indexed as a schematic.

Short PDF of 50.8 KB for the 2SC1509, with an _E suffix in the file name, listed in the schematic section.

A 190 KB PDF holding the data document for the 2SB1640 transistor, indexed under schematics.

Datasheet covering the 2SB1592 PNP transistor in a compact 38.9 KB PDF; the _E tag likely indicates the English version of the document.

Data document for the 2sb1590k, a 34.8 KB PDF listed under schematics. The 2SB part follows JIS numbering for PNP low-frequency bipolar transistors; the trailing K is a…

Reference document for the 2SB1398 transistor, with an _E suffix in the name that is not explained and may indicate an edition or language version.

The 2SA1592 is covered by this 156 KB PDF, filed as a schematic although the name refers to a single semiconductor.

An 89.5 KB PDF for the 2SA1590 transistor, listed under schematics but almost certainly a part datasheet given the name.

Named after the 2SA1537 transistor, this 41.0 KB PDF sits in the schematic category but should contain the manufacturer data for that part.
