Part reference for the 2SD1669, supplied as a 107 KB PDF and filed in the schematic section.

PDF of 119 KB for the 2SD1664, written in lowercase in the original name and filed as a schematic.

At 198 KB, the PDF for the 2SD1658 is one of the larger sheets in this group, though it still names only the part.

Datasheet PDF, 60 KB, for the 2SD1650, with the name given in lowercase and filed under schematics.

The 2SD1628 is covered in this 88.3 KB PDF, catalogued with schematics though it relates to a single transistor.

Indexed as a schematic, this 109 KB PDF is titled 2SD1621, a transistor part number, so treat it as a datasheet rather than a circuit diagram.

Part number 2SD1424 with an unexplained _E suffix names this 41.4 KB PDF, indexed among schematics but most likely a datasheet for the transistor.

Component documentation for the 2SD1881 transistor, supplied as a 90.6 KB PDF and catalogued as a schematic, though a part number like this normally points to a…

PDF covering the 2SD1880, about 88.9 KB, listed as a schematic but named after a single semiconductor part.

Document for the 3SK227 semiconductor, stored as a 30.6 KB PDF and catalogued under schematics.

PDF document for the 2SD1995 semiconductor, catalogued under schematics but by its name a component datasheet.

The 2SD1511 NPN transistor is the subject of this 56.9 KB PDF, filed under schematics in the index. JIS numbering assigns 2SD to low-frequency NPN bipolar parts.

The name carries only a part number, 2SD1905, which points to a semiconductor datasheet even though the entry is filed under schematics.

Filed under schematics, though the file name is simply the JIS part number 2SD1903, so expect a component datasheet in this 131 KB PDF.

The 2SK3413LS is documented in this compact 32.2 KB PDF, indexed as a schematic but effectively a component datasheet.

Datasheet-type PDF of 31.1 KB for the 2SK3412 semiconductor, stored under the schematic category.

Covering the 2SK3335, this small PDF (32.6 KB) is a part datasheet placed in the schematic category.

The 2SK3291 transistor is the subject of this 34.2 KB PDF, filed as a schematic although it works as a datasheet.

PDF reference for the 2SK2825, 301 KB in size and listed in the schematic section. The 2SK designation, from the Japanese JIS numbering system, belongs to N-channel…

Indexed as a schematic, this 99.3 KB PDF is titled 2SK2406 and is most probably a datasheet for an N-channel field-effect transistor, as the 2SK prefix indicates under…

The file name gives nothing beyond 2SK2233, a JIS/EIAJ designation whose 2SK prefix marks an N-channel field-effect transistor.

PDF for the 2SK1739A, 197 KB, listed as a schematic. The 2SK prefix follows the Japanese JIS designation for N-channel field-effect transistors, and the trailing A…

PDF documentation for the 2SK1731 discrete semiconductor, roughly 90 KB in size. Japanese 2SK numbering identifies it as an N-channel FET; the name says nothing about…

At 120 KB, this PDF is a slightly larger reference for the 2SK1728. Japanese JIS/JEITA numbering assigns the 2SK series to N-channel field-effect transistors, so expect…

Short 31.7 KB PDF for the 2SK1460LS, an N-channel FET by the Japanese 2SK prefix, carrying an LS suffix that distinguishes it from the plain 2SK1460 also in this index.

Covering the 2SK1435, this 105 KB PDF is indexed as a schematic yet named after one discrete component, which suggests a datasheet.

Datasheet-style PDF of 104 KB for the 2SK1433, placed in the schematic category of the index.

Small 33.4 KB PDF covering the 2SK1406 field-effect transistor from the Japanese 2SK numbering series, which designates N-channel FETs.

Compact 33.4 KB PDF for the 2SK1374, a Japanese-numbered N-channel MOSFET. Only the part number appears in the file name, so the issuing manufacturer and exact package…

Datasheet PDF for the 2SK1058, a 55 KB file. This part number belongs to the 2SK series of N-channel field-effect transistors and is widely known from audio power…

Small 35.2 KB PDF identified only by the part number 2SK665, a designation from the Japanese 2SK family of N-channel FETs, so the content is most likely a component…

The 2SJ407 is documented in this 398 KB PDF, catalogued as a schematic though it is a component datasheet by name.

Here is a 151 KB PDF for the 2SD1230, filed under schematics although it relates to one transistor type.

Datasheet for the 2SD1187 transistor in PDF form, 227 KB, which is larger than most sheets in this series and may include more curves or package options.

Listed in the schematic category, this small 105 KB PDF is in practice a component document for the 2SD1064 part.

Reference sheet for the 2SD1062 transistor in PDF form, about 104 KB, catalogued under schematics.

For the 2SD1011, this 42.1 KB PDF carries an _E tag in the name with no stated meaning.

Reference PDF for the 2SD973, 53.5 KB, with an _E suffix the name leaves undefined. It sits in the schematic category, but the JIS 2SD prefix marks an NPN transistor for…

Datasheet for the 2SD662 NPN transistor, stored as a 44 KB PDF; the _E ending likely marks an English version of the document.

Here is a 144 KB PDF for the 2SC4728, filed as a schematic but carrying a discrete part number.
