Filed under schematics, this 413 KB PDF is named after the 2SK2838. The 2SK prefix in the JIS system indicates an N-channel FET, so the file most likely holds the…

A 429 KB PDF titled 2SK2789 and stored among schematics, most likely the datasheet for that part.

Part documentation for the 2SK2731, a 113 KB PDF placed in the schematic category. JIS naming assigns the 2SK prefix to N-channel field-effect transistors, so the…

A 166 KB PDF covering the 2SK1961 transistor. The 2SK series in the JIS system denotes N-channel FETs, so this schematic-categorised file should be read as a component…

Only the part number 2SK1897 identifies this 97.1 KB PDF, which the index places among schematics.

Documentation for the 2SK1431, a part whose 2SK prefix places it among N-channel FETs under Japanese JIS numbering.

A brief 34.4 KB PDF describing the 2SK1267 N-channel MOSFET from the Japanese JIS 2SK numbering range.

The 2SK1237 N-channel transistor is the subject of this 45.8 KB PDF, filed under the schematic category.

Short 34.3 KB PDF for the 2SK1228 N-channel field-effect transistor, catalogued among schematics. The 2SK prefix identifies a JIS-registered Japanese N-channel FET.

Compact 31.0 KB PDF for the 2SK662, a JIS-registered N-channel field-effect transistor number, most likely the manufacturer datasheet despite its schematic label.

Part reference for the 2SK242, saved as a 170 KB PDF in the schematic section. Japanese JIS designations beginning with 2SK belong to N-channel FETs, so the file is most…

This catalogue entry covers a 118 KB PDF called 2SJ192, a Japanese JIS part number for a P-channel field-effect transistor; although filed under schematics, it is likely…

A 144 KB PDF whose name is just the part number 2SD1190, filed as a schematic but in practice a transistor datasheet.

The 2SD1046 is documented in this 115 KB PDF, placed in the schematic group. Its name carries no detail other than the part number.

Covering the plain 2SC5261 without suffix, this 183 KB PDF is indexed as a schematic but concerns a single NPN bipolar transistor, as the JIS 2SC prefix indicates.

Covering the 2SC4632, this 89.2 KB PDF sits in the schematic category, yet its name matches a transistor part number.

The 2SC5226 is covered by a 112 KB PDF that the index classes as a schematic, though the name indicates a component datasheet.

Indexed under schematics, the 116 KB PDF named 2SC5155 refers to a discrete semiconductor rather than a whole board.

Only the part number 2SC4563 identifies this 85.4 KB PDF, categorised as a schematic but best treated as a datasheet for a JIS-designated NPN bipolar transistor of the…

A 91.7 KB PDF bearing the JIS part number 2SC4437, catalogued as a schematic. The 2SC prefix classifies it as an NPN bipolar transistor for high-frequency use, so the…

Bearing only the number 2SC4293, this 92.7 KB PDF is catalogued under schematics while most likely holding the datasheet for that transistor.

PDF reference, about 124 KB, for the 2SC3776 transistor. The JIS 2SC prefix identifies an NPN bipolar part, so although the file is labelled a schematic it most likely…

Specification PDF for the 2SC4924 NPN transistor, roughly 79 KB. No manufacturer, package or application appears in the name, only the JIS-style part number.

At 217 KB, this PDF for the 2SC3673 is one of the larger documents in the 2SC367x group and is indexed as a schematic.

Catalogued as a schematic, this 149 KB PDF is labelled just 2SC3416, a JIS designation in which 2SC marks an NPN bipolar transistor.

A 41.1 KB PDF named for the 2SC3312 part, listed as a schematic yet in practice a component datasheet.

Part number 2SA1533 names this 51.3 KB PDF, with an unexplained _E suffix; despite the schematic category it is presumably the transistor datasheet.

At 95.1 KB this is one of the larger files in the set, a PDF named after the 2SB1205 transistor and indexed as a schematic, though it is presumably the datasheet.

Reference sheet for the 2SB1184, a part number in the Japanese JIS series where 2SB indicates a low-frequency PNP bipolar transistor.
