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

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.

Compact 43.6 KB PDF named for the 3N249 and filed as a schematic, although it is almost certainly a component datasheet.

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

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.

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

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

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…

Reference PDF for the 2SK2714 transistor, 144 KB, filed in the schematic section. JIS naming uses 2SK for N-channel field-effect transistors, so the contents should be 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.

Only the part number 2SK2221 names this small 55 KB PDF, which is catalogued as a schematic but most likely serves as a component datasheet.

A 398 KB PDF for the 2SK2034, a part in the Japanese 2SK series of N-channel field-effect transistors.

PDF document for the 2SK1921, filed under schematics although the name is simply a semiconductor part number.

The 2SK1826 datasheet in PDF form, sized 320 KB and filed as a schematic. Japanese JIS designations starting with 2SK identify N-channel field-effect transistors.

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…

Datasheet-type file for the 2SK1464 N-channel field-effect transistor, 120 KB in PDF form and indexed as a schematic.

Catalogued under schematics, this 112 KB PDF is tied to the 2SK1450 and is most likely a component data sheet.

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

Covering the 2SJ612, this 29.0 KB PDF sits in the schematic category, though a bare part number usually denotes a datasheet.

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

The 2SJ377 is covered by this 415 KB PDF, a component datasheet filed in the schematic category.

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.

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…

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

A 24.2 KB PDF for part 2SC5287, an NPN transistor by Japanese JIS designation. Though tagged as a schematic, a part-numbered file like this is normally a datasheet…

A 126 KB PDF dedicated to the 2SC5257, sorted into the schematic section although the name identifies a single component.

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…

The 2SC5238 is covered by this 105 KB PDF, filed among schematics but named like a discrete-component datasheet.

Documentation for the 2SC4781 in a 120 KB PDF, indexed as a schematic though the name matches a discrete semiconductor part.

Component document for the 2SC5201 part number, catalogued as a schematic but almost certainly a semiconductor datasheet given the name and small 115 KB PDF size.

PDF of about 63 KB for part 2SC4618, with a trailing h in the name whose meaning is not stated and may denote a variant or document version.

Listed as a schematic, this 103 KB PDF is titled with the device code 2SC4461. In the JIS semiconductor naming scheme, 2SC stands for an NPN bipolar transistor meant for…

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