PDF sheet of 38.4 KB for the 2SD2575, with an _E suffix in the file name. Filed as a schematic, it most likely holds datasheet content, because 2SD is the JIS code for…

Datasheet for the 5HP01N part in PDF form, about 27 KB. No device or motherboard is named; the code with an N ending appears to be a package variant of the 5HP01 series.

A 41.8 KB PDF named for the 2SD2457 with an E tag, filed as a schematic. By the JIS scheme, 2SD marks an NPN bipolar transistor, so expect a component reference rather…

Covering the 2SK3495, this 28.0 KB PDF carries the schematic tag yet is named after one JIS part, pointing to a brief datasheet.

A 418 KB PDF named for the 2SK2742, an N-channel field-effect transistor under the Japanese JIS 2SK prefix, placed in the schematic category.

The 2SK2740 transistor is the subject of this 143 KB PDF, filed as a schematic even though the name points to a component datasheet.

Reference sheet for the 2SK2739 in PDF format, 146 KB, indexed in the schematic section.

PDF for the 2SK2504 with an added _1-5 suffix in the name, 135 KB in size; the suffix meaning is not stated and may indicate a page range or alternate edition.

A 40.8 KB PDF on the 2SK2012, an N-channel FET according to the JIS 2SK naming convention.

A 110 KB PDF dedicated to the 2SK1922, which the JIS 2SK prefix identifies as an N-channel field-effect transistor.

Part number 2SK1906 is all the name reveals about this 96.0 KB PDF, which sits in the schematic category.

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.

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

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

Datasheet-like PDF, 42.5 KB, for the 2SJ583LS and filed as a schematic. Japanese JIS designations starting with 2SJ belong to P-channel FETs, and the LS suffix points to…

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

Reference sheet for the 2SD1313 transistor, stored as a 206 KB PDF and filed under schematics.

Datasheet-style PDF for the 2SD1302, 46.0 KB, listed in the schematic category. The 2SD prefix follows the Japanese JIS designation for NPN bipolar transistors in…

Compact 44.8 KB PDF for the 2SD1051, with an _E suffix in the name whose meaning is not stated, possibly a language or edition marker.

The 2SD968 is covered by this 42.9 KB PDF, whose name includes an _E suffix with no explanation given.

Specification sheet for the 2SD874 transistor in PDF form, about 44 KB, catalogued with the schematics but actually a component datasheet.

Datasheet for the 2SD814 NPN transistor, a 42 KB PDF whose _E suffix probably indicates an English edition.

Datasheet for the 2SD669 NPN transistor in a small 32 KB PDF, maker not stated in the file name.

The 2SC4688 transistor is documented in this 178 KB PDF, which the catalogue files under schematics.

At only 34.3 KB, this PDF for 2SC4453 is probably a short datasheet of a page or two, even though it is catalogued as a schematic.

A 187 KB PDF named after the 2SC4408 part number and listed in the schematic category. JIS numbering uses 2SC for NPN bipolar transistors, so treat the file as a…

Component documentation for the 2SC4269 in PDF form, 108 KB in size, listed in the schematic category. Nothing beyond the part number appears in the name.

Part number 2SC4223 is all the file name gives, so this 93.9 KB PDF is best treated as a datasheet for that component rather than a circuit schematic.

Datasheet-style PDF, 95.3 KB, for the 2SC4222 transistor. It is indexed as a schematic, but the name holds only the part number.

At 108 KB, this PDF is labelled with the transistor type 2SC4221 and nothing else, so no board, model or revision is identified.

Small 44.2 KB PDF for the 2SC5541, filed as a schematic though the part code points to an NPN bipolar transistor under the Japanese JIS system.

PDF for the 2SC4061K, 61.7 KB, filed under schematics though the name reads as a component datasheet.

The 2SC3996 is covered by this 91.9 KB PDF, sorted under schematics although a name consisting only of a part code usually means a datasheet.

Only the type number 2SC4836 appears in the name of this 110 KB PDF, indexed as a schematic.

PDF documentation for the 2SC4793 transistor, at 173 KB larger than most files in this series and probably a fuller datasheet with characteristic curves.
