PDF datasheet of about 56 KB for the 2SD661 transistor, with an _E suffix that probably indicates an English edition.

The 2SC4690 is the subject of this 175 KB PDF, which the index files as a schematic even though the name points to a single transistor document.

A 161 KB PDF carrying only the part number 2SC4650, a JIS-registered NPN transistor. Nothing in the name links it to a specific device, so treat it as a component…

A 39.6 KB PDF for the 2SC5216, with an _E tag in the name that is not explained. It is listed as a schematic, but the name points to a transistor datasheet.

Catalogued as a schematic, this 184 KB PDF is named only after the part number 2SC5175, so it is most likely the manufacturer datasheet for that discrete transistor.

The 2SC5171 named in this 169 KB PDF is a JIS-style part number, where the 2SC prefix denotes an NPN bipolar transistor for high-frequency applications, so the content…

A compact 93.8 KB PDF carrying only the designation 2SC4476 in its name. Under JIS numbering the 2SC prefix identifies an NPN transistor of the high-frequency class, so…

Datasheet-style PDF of 119 KB for the 2SC4401, listed in the index under schematics although the name points to a single semiconductor part.

A 42.8 KB PDF for the 2SC5639, placed under schematics although its name is a bare part number pointing to a transistor datasheet.

Smallest of the batch at 30.8 KB, the PDF named 2SC5607 is presumably a concise datasheet for that NPN transistor despite being labelled a schematic.

A 51.7 KB PDF for the 2SC4208, with an _E suffix in the name whose meaning is not stated; it could mark an edition or language version, but that is unconfirmed.

Despite sitting in the schematic category, this 99.9 KB PDF is named after the 2SC4164 and should therefore contain transistor specifications rather than a circuit…

The name of this 156 KB PDF is just the part number 2SC4134, so despite its schematic label it should be the datasheet for that transistor.

The 2SC5774 part number is all this 29.9 KB PDF name reveals, and the catalogue lists it as a schematic.

Compact 43.3 KB PDF covering the 2SC5551, a JIS-coded NPN bipolar transistor, even though the catalogue type says schematic.

For the 2SC5534 transistor, this 44.8 KB PDF sits in the schematic category but, going by the JIS 2SC code for NPN bipolar devices, is the part datasheet.

Catalogued as a schematic, this 45.8 KB PDF is named after the 2SC5503, a part number in the Japanese 2SC series used for NPN bipolar transistors.

A 39.3 KB PDF for the 2SC5490 component, which belongs to the 2SC range of NPN bipolar transistors under Japanese JIS numbering.

Filed under schematics, the 2SC3993 PDF (107 KB) is far more likely a component datasheet, since the name is simply a JIS transistor part number.

Reference PDF for the 2SC5420 transistor, 69.2 KB, indexed as a schematic though the bare part number points to a component datasheet.

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…

The 2SC3502 NPN transistor is the subject of this 157 KB PDF, which the index files under schematics.

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

Datasheet PDF of 172 KB carrying the part number 2SC5358, listed under schematics in the index.

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

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

A 29.2 KB PDF carrying the part number 2SB1683, a PNP transistor by Japanese JIS naming; though labelled as a schematic, it is expected to be the component datasheet.

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.

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.

Reference PDF, 88.0 KB, for the 2SA1582 transistor. The file name states only the part number and nothing about the maker, package or application.

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