Component documentation for the 2SK1904, provided as a 95.2 KB PDF and filed as a schematic.

At 287 KB this PDF for the 2SK1875 is larger than its neighbours, which may mean extra graphs or pages, though the name says nothing more than the part number.

Datasheet-type PDF for the 2SK1737, sized 90.0 KB and categorised as a schematic. The 2SK prefix comes from the Japanese JIS naming scheme for N-channel field-effect…

PDF, 87.5 KB, for the 2SK1735 semiconductor. Part numbers beginning 2SK are registered in the Japanese JIS scheme as N-channel field-effect transistors, making this most…

PDF document for the 2SK1530, filed under schematics although the name is only a semiconductor part number.

A 117 KB PDF catalogued as a schematic but named after the 2SK1458 part number, so it most likely holds the manufacturer's data sheet for that semiconductor.

Part reference for the 2SK1452 in PDF form, 111 KB, classified as a schematic. The name states only the device number.

A 109 KB PDF for the 2SK1446, catalogued as a schematic and probably the main data sheet for this transistor.

The 2SK1429 is covered by this compact 99.1 KB PDF, entered in the schematic category although a lone part number usually signals a datasheet.

The 2SK1412 is a Japanese-registered N-channel MOSFET, and this 110 KB PDF is its reference document, catalogued as a schematic.

The 2SK1266 N-channel field-effect transistor is documented in this 33.9 KB PDF, indexed as a schematic.

Part reference sheet in PDF form for the 2SK663, carrying a 2SK prefix that under the Japanese JIS system denotes an N-channel FET.

PDF of 32.5 KB covering the 2SK656, a part from the JIS 2SK range of N-channel field-effect transistors, so it is effectively a component datasheet rather than a device…

Covering the 2SK443, this 95.2 KB PDF sits under schematics, though the JIS 2SK naming for N-channel field-effect transistors indicates a component datasheet.

Reference sheet for the 2SJ620 in PDF form, 345 KB, listed in the schematic category. The 2SJ prefix follows the Japanese JIS scheme for P-channel field-effect…

Here the only information in the name is 2SJ525, a Japanese-standard part code where 2SJ marks a P-channel field-effect transistor.

Under the JIS semiconductor scheme the name 2SJ464 refers to a P-channel FET, and this 320 KB PDF, although indexed as a schematic, should be its datasheet.

A 110 KB PDF labelled 2SJ440 and listed under schematics. The 2SJ prefix is the Japanese JIS code for P-channel field-effect transistors, so the content is likely a…

The 2SJ382 P-channel FET is described in this 96.9 KB PDF, filed as a schematic though it is a component datasheet.

The 2SJ344 is covered by this 310 KB PDF, which the catalogue lists under schematics. The file name carries nothing beyond the part number.

PDF for the 2SJ306, about 94.4 KB. The name contains just the transistor type, so no device, board or revision can be stated.

A compact 27.8 KB PDF named after 2SJ164, a JIS designation identifying a P-channel FET.

Named 2SD1350_E, this 44.0 KB PDF sits in the schematic category but most likely holds the datasheet for the 2SD1350, an NPN low-frequency bipolar transistor under…
