Nokia N90 schematics in a 1.35 MB PDF, separate from the other numbered N90 parts in the collection.

Datasheet in PDF form for the 2SK3565, an N-channel field-effect transistor by its 2SK prefix under the Japanese JEDEC-style numbering.

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…

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.

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

Part data for the 2SC4686A in a 208 KB PDF, catalogued with schematics. JIS numbering marks 2SC as an NPN bipolar transistor, and an A suffix normally points to a…

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…

Here is the 2SC5242 documentation as a 173 KB PDF, placed in the schematic category but evidently a part datasheet going by its name.

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.

Small 56 KB PDF covering the 2SC4626 part, with an _E suffix that possibly marks an English-language version of the original document.

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.

Small 39.3 KB PDF covering the 2SC4562, with an unexplained _E suffix in the name, listed under schematics.

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…
