Datasheet for the 2SD2216J, a 40.5 KB PDF listed as a schematic. The J is part of the type designation and marks a variant of the 2SD2216, so the exact suffix should be…

A 40.6 KB PDF for the component 5HN02C. Although classed as a schematic, the file name contains just a part code, with C probably denoting the package, and states no…

A 171 KB PDF for the 4N39 and 4N40 optocouplers, listed under schematics but in practice a component datasheet.

Component sheet covering the 3N254, delivered as a 42.2 KB PDF and indexed as a schematic. JEDEC numbers beginning with 3N denote registered devices having four leads.

Datasheet-style PDF of 27.2 KB for the 2SK2682, a JIS-designated N-channel FET; it is listed under schematics but describes a single component.

Compact 65.7 KB PDF for the 2SK2539, listed as a schematic but named after a discrete semiconductor.

Sized at 111 KB, a PDF for the 2SK2394 that the index lists under schematics, though its JIS-style part number indicates a datasheet for an N-channel field-effect…

Reference sheet in PDF form for the 2SK2349, sized 54.7 KB and listed in the schematic category.

The 2SK2152 is covered by this 93 KB PDF, listed as a schematic but named only by its part number, so it is most likely the transistor's datasheet.

The 2SK1891 transistor is covered by this 96.0 KB PDF, which the index lists as a schematic.

Component datasheet in PDF, 86.7 KB, for the 2SK546, listed among schematics. Following JIS numbering, 2SK parts are N-channel FETs, so the document covers a single…

A small 31.5 KB PDF identified only by the part number 2SK374. Under JIS numbering the 2SK series covers N-channel FETs, so the content is almost certainly a short…

Documentation for the 2SJ378 P-channel FET in a 418 KB PDF, listed as a schematic though really a datasheet.

An 88.9 KB PDF for the 2SD1247, indexed as a schematic although the name identifies a single semiconductor.

Compact UTC datasheet, around 14 KB, for the 2SD880 NPN transistor from Unisonic Technologies.

Reference sheet for the 2SC5298 in a 95.7 KB PDF. Parts with the 2SC prefix are NPN bipolar transistors under the Japanese JIS numbering system, so the content is likely…

The 2SC5263 is covered by this 103 KB PDF, listed among schematics in the index. Following Japanese JIS numbering, 2SC marks an NPN bipolar transistor, and no variant…

A 271 KB PDF for the 2SC5232, listed as a schematic yet named like a single-component datasheet. JIS numbering gives the 2SC prefix to NPN bipolar transistors.

A 136 KB PDF for the 2SC4616, listed among schematics though the name only carries a component part number, implying a transistor datasheet.

Small 92.6 KB PDF bearing only the part number 2SC4219. Although the catalogue lists it as a schematic, the 2SC prefix, the JEITA code for an NPN bipolar transistor…

PDF of 49.6 KB named 2SC5565, catalogued with the schematics although it refers to a single semiconductor.

Datasheet-style PDF of 181 KB for the 2SC5819 transistor, listed under schematics in the index.

Covering the 2SC5472, this 38.0 KB PDF carries an _E suffix that probably means an English edition.

Part 2SC5075 gives this 220 KB PDF its name; the catalogue lists it as a schematic, but under Japanese JIS naming the 2SC code means an NPN bipolar transistor, so a…

Reference PDF for the 2SC4869, 126 KB, sorted into the schematic category. Nothing else is given in the name.

Listed among schematics, this 155 KB PDF is named after the transistor type 2SC3788 and gives no further details such as maker or case.

Data sheet material for the 2SC3772 NPN transistor in a 128 KB PDF, filed among schematics. The 2SC prefix follows the JIS convention for Japanese bipolar transistors.

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.

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

PDF of 30.1 KB covering the 2SA1520, listed as a schematic yet named like a single-part data sheet. JIS numbering places 2SA parts among PNP bipolar transistors.

The 2SB1140 is covered by this 103 KB PDF, catalogued in the schematic section. Japanese JIS numbering assigns 2SB to PNP transistors meant for low-frequency service, so…
