Covers the 2SD2218 NPN transistor in a 122 KB PDF filed under the schematic category. Only the transistor type appears in the name.

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

Datasheet-style document for the 2SD2581 transistor, saved as a 43.7 KB PDF and filed in the schematic category.

Part datasheet for the 2SD1782K, an NPN transistor named under the Japanese JIS scheme, with the K suffix indicating a particular variant or package.

The name offers nothing beyond the 2SD2500 part number, and the 250 KB PDF is almost certainly that transistor's datasheet.

Transistor documentation for the 2SD1667, 136 KB in PDF format. Nothing beyond the part number appears in the name.

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.

Small 33.0 KB PDF for the 3SK144, catalogued as a schematic but named for an individual semiconductor, so it is most likely a datasheet.

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

Reference sheet for the 3SK180 semiconductor in PDF form, roughly 173 KB, catalogued as a schematic.

Short 54.7 KB PDF for the 2SD1991A, an NPN bipolar transistor going by its JIS 2SD prefix. The index lists it under schematics.

Tiny 30.2 KB PDF named 2sk65, a JIS part number that indicates a component datasheet, although it is filed as a schematic.

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

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…

Part reference for the 2SK2782, delivered as a 419 KB PDF under the schematic label. The 2SK prefix follows Japanese JIS numbering for N-channel field-effect…

PDF reference for the 2SK2749 transistor, 412 KB, stored in the schematic section. Under Japanese JIS numbering the 2SK prefix identifies an N-channel field-effect…

Part document for the 2sk2575, 35.2 KB in PDF format and catalogued as a schematic. The 2SK prefix in JIS nomenclature marks an N-channel field-effect transistor; the…

Reference sheet in PDF format for the 2SK2549 field-effect transistor, 373 KB in size. In the JIS numbering used by Japanese semiconductor makers, 2SK denotes an…

Brief PDF, about 30.2 KB, for the 2SK2509, a JIS-designated N-channel FET as indicated by its 2SK prefix.

The 2SK2504 transistor is documented in this 134 KB PDF, named in lowercase and catalogued under schematics.

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

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.

A 96.5 KB PDF identified only as 2SK1889 and filed under schematics. Under the JIS scheme the 2SK prefix indicates an N-channel field-effect transistor, so the file most…

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…
