PDF schematic labelled only 1002, in an unlocked version with document protection removed so pages can be printed and searched.

Schematic PDF of 1.6 MB named only Y300, which most likely refers to a Lenovo IdeaPad Y300-series device, though the name does not state the brand or board number.

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

Schematic for a Nokia phone listed as model 26110 in a 1.87 MB PDF. The number as written does not match a familiar Nokia model, so it may be a typo for another handset…

PDF schematic section for the SM6150 processor, also tagged SM61, about 1.26 MB, with no device model specified.

Datasheet for the 2SD612K transistor, a 303 KB PDF listed in the schematic section. The K at the end belongs to the type number and indicates a variant of the 2SD612…

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

Part 5LP01N is documented in this 27.9 KB PDF, filed under schematics. The name is limited to the part code; in this family LP appears to designate a P-channel MOSFET…

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

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.

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.

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

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

The 3N248 is covered by this 43.6 KB PDF, indexed under schematics but named only by its JEDEC part number.

Part number 2SD2459 names this 41.2 KB PDF, followed by an unexplained E tag; it is catalogued as a schematic.

Largest in this set at 269 KB, the PDF 2SD2414 is catalogued as a schematic, yet its 2SD prefix marks an NPN bipolar transistor under the Japanese JIS scheme.

The name carries only a part number, 2SD1905, which points to a semiconductor datasheet even though the entry is filed 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.

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…

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…

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…

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…

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.

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…
