Reference PDF for the CD4094, an eight-stage shift-and-store bus register from the CMOS 4000 series, as the name notes it is a shift register.

This PDF of about 124 KB covers the 2SD2114 transistor with a KS suffix; the suffix is not explained by the name and may denote a gain class or package variant.

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.

For the 2SK3411 transistor, this 32.0 KB PDF provides the component reference, even though the index files it as a schematic.

Datasheet-style PDF for the 2SK3018, indexed here under schematics, though the 2SK prefix marks a Japanese JIS-registered N-channel field-effect transistor rather than a…

Part number 2SK2231 is the only information carried by this 420 KB PDF, which the index places among schematics but which most likely documents a single transistor.

Compact 31.6 KB PDF dedicated to the 2SK2032. Because 2SK identifies an N-channel field-effect transistor in the Japanese numbering scheme, this is effectively a…

PDF datasheet of 287 KB for the 2SK2009, an N-channel field-effect transistor under the Japanese 2SK designation.

The 2SK1920 is the only detail in this file name, and the 93.1 KB PDF is indexed as a schematic.

Part 2SK1890, documented in a 96.7 KB PDF placed in the schematic category. Japanese JIS numbering reserves 2SK for N-channel FETs, so this is a component datasheet…

For the 2SK1470, a Japanese-coded N-channel field-effect transistor, this 97.9 KB PDF serves as component reference material even though it sits in the schematic…

Reference PDF for the 2SK1382 N-channel MOSFET, 389 KB, listed in the schematic category of the index.

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…

PDF covering the 2SK1104, an N-channel FET identified by the 2SK prefix of the Japanese semiconductor numbering system.

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…

Part documentation for the 2SJ337 in a 98.2 KB PDF. The file name names only this semiconductor, nothing about a device.

This 93.0 KB PDF carries the part number 2SJ258 and nothing else. The 2SJ prefix, under Japanese JIS numbering, indicates a P-channel field-effect transistor, so expect…

Named only 2SJ232, this 88.9 KB PDF relates to a P-channel field-effect transistor, as indicated by the JIS 2SJ prefix.

The 123 KB PDF bears the part number 2SC4644 and nothing else. That makes it a reference for a single NPN transistor rather than a full circuit diagram, despite the…

Filed under schematics, this 244 KB PDF is named after the part number 2SC4479, which follows the Japanese JIS scheme where the 2SC prefix marks an NPN bipolar…

PDF of about 113 KB identified by the transistor number 2SC4403. The JIS prefix 2SC marks an NPN bipolar transistor, so this document should provide datasheet…

Reference PDF for the 2SC4224, at 97.3 KB, catalogued as a schematic although the name is just a semiconductor part number.

Short 30.1 KB PDF for the 2SC5778 transistor, placed in the schematic category. Japanese JIS codes beginning with 2SC denote NPN bipolar devices, so the contents are…

The 2SC5488 is covered by this 34.5 KB PDF, indexed as a schematic. Since 2SC numbers designate NPN bipolar transistors in the Japanese JIS system, the file is likely a…

Filed as a schematic at 106 KB, this PDF bears only the identifier 2SC5070. That code belongs to the Japanese 2SC series of NPN transistors, so the document should be a…

Specification document for the 2SC4782 transistor, saved as a 46.9 KB PDF whose _E ending likely marks an English version.

Compact 38 KB PDF named for the 2SC5380 transistor. The 2SC numbering marks an NPN device under the Japanese JIS scheme; the name gives no manufacturer or application.

Compact 33.5 KB PDF for the 2SC3664 transistor. The 2SC prefix, under the JIS scheme, signals an NPN bipolar device; nothing else is stated in the name.

Catalogued as a schematic, this 127 KB PDF carries only the designation 2SC3466 in its name.

Filed under schematics, this 209 KB PDF is named after the part number 2SC3405, which follows the Japanese JIS scheme where the 2SC prefix marks an NPN bipolar…

The 140 KB PDF is identified only by the transistor number 2SC3393 and contains no board or model reference.

Small 41.7 KB PDF for the 2SC5346; the _E suffix possibly marks an English edition, though the name alone cannot confirm this.

Datasheet PDF of 248 KB for the 2SC3138, an NPN bipolar transistor going by its Japanese JIS 2SC prefix.

Brief 41.4 KB PDF for the 2SC3117, which JIS numbering identifies as an NPN bipolar transistor.

A 145 KB PDF labelled only 2SC2839, catalogued under schematics. The JIS 2SC prefix indicates an NPN bipolar transistor, so this is most likely a datasheet rather than a…

Part reference for the 2SC1518 in a 51.5 KB PDF carrying an _E suffix, filed under schematics.

Short PDF of 38.2 KB covering the 2SA1635, a part number that follows the Japanese JIS scheme where 2SA identifies a high-frequency PNP bipolar transistor.

Named only as 2SA1924, this 198 KB PDF sits in the schematic category but most likely holds the datasheet for that part.

Datasheet PDF for the 2N4031 part number, 52.3 KB in size, placed in the schematic category of the index.
