Covering the 2SD2645, this 29.3 KB PDF sits in the schematic index although the name suggests a component datasheet.

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.

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

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…

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.

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

Here the 2SK3285 is documented in a 48.6 KB PDF, placed in the index's schematic section.

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…

Reference PDF for the 2SK2711, about 140 KB, listed in the schematic category though the part number points to a discrete transistor datasheet.

Brief 34.7 KB PDF for the 2sk2581 transistor, catalogued as a schematic. JIS naming assigns 2SK to N-channel field-effect transistors, and the name gives no further…

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 2SK2312 is covered by this 391 KB PDF, catalogued under schematics yet most likely a component datasheet.

The 2SK2267 named here is an N-channel FET under the Japanese JIS/EIAJ scheme, where 2SK denotes that transistor class.

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

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 reference, 115 KB, for the 2SK1924 N-channel field-effect transistor; the 2SK prefix places it in the Japanese JIS transistor registry.

PDF datasheet, 173 KB, covering the 2SK1740. The 2SK series in JIS nomenclature consists of N-channel FETs, and this document is likely its specification sheet.

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

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

Datasheet-type PDF for the 2SK536, 60.8 KB, catalogued under schematics. Under the Japanese JIS system the 2SK designation means an N-channel FET, so the content…

Covering the 2SJ589LS, this 33.2 KB PDF is catalogued as a schematic, though the name points to a component datasheet.

Brief 24.7 KB PDF for the 2SJ0398, written with a leading zero in the name, which most likely refers to the 2SJ398 P-channel FET in JIS numbering.

Catalogued among schematics, this 103 KB PDF is labelled only 2SJ263. In the Japanese JIS designation system the 2SJ prefix covers P-channel field-effect transistors, so…

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

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

Unisonic Technologies (UTC) specification sheet for the base 2SD882 NPN transistor, supplied as a 22 KB PDF.

A 155 KB PDF bearing the part number 2SC4734 and nothing else. The 2SC prefix belongs to the JIS/JEITA system for NPN bipolar transistors, so despite the schematic label…

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

A 247 KB PDF titled only with the part number 2SC4667, catalogued here as a schematic. The 2SC prefix is the JIS code for an NPN transistor intended for high-frequency…

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…
