Schematic diagrams for the Nokia 7210 colour-screen phone, a 4.56 MB PDF. The name provides only the model, with no board number or revision, so confirm the main board…

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…

Troubleshooting chapter for the Samsung GT-S7580 and GT-S7582 phones, section 7 of the service manual, in a 3.08 MB PDF.

HCF4050 reference document in PDF format, 175 KB, covering the 4050 hex non-inverting buffer in its HCF-prefixed version.

Reference PDF for the CD4094, an eight-stage shift-and-store bus register from the CMOS 4000 series, as the name notes it is a shift register.

PDF reference of 116 KB for the CA3306, a CMOS flash analog-to-digital converter in the Intersil and Harris CA-series line.

Component documentation for the 2SD2257 transistor, in PDF form at 180 KB. Although the index lists it as a schematic, the file name points to a single discrete part…

PDF datasheet, 40.9 KB, for the 2SD2240 transistor, filed under schematics in this index. An _E suffix in the name is an edition marker for the document only.

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-type PDF, 30.8 KB, for the 2SD2627LS, catalogued as a schematic. The LS suffix is part of the type designation and likely refers to a specific variant or…

PDF of 75.0 KB covering the 2SD2176 part. Though listed as a schematic, a file named after a single JIS transistor number is most likely a datasheet, and the 2SD prefix…

Single-part PDF of 47.0 KB for the 2SD2583, listed as a schematic but most probably a datasheet.

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

Compact 42.8 KB PDF for the 2SD2537, listed as a schematic though the name points to a single-component datasheet.

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…

A 41.4 KB PDF covering the 5HP02C part, indexed under schematics. Only the component code is present in the name, with C most likely denoting the package type.

Component documentation for the 4N38 optocoupler, filed under schematics though it is in practice a part datasheet in PDF form of about 140 KB.

The 2SD2079 PDF, 219 KB in size, is indexed as a schematic yet corresponds to a single discrete component.

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

The 2SD1683 is the subject of this 146 KB PDF, which is catalogued as a schematic although the name is a transistor part number.

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

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

At 198 KB, the PDF for the 2SD1658 is one of the larger sheets in this group, though it still names only the part.

Datasheet PDF, 60 KB, for the 2SD1650, with the name given in lowercase and filed under schematics.

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

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.

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…

PDF covering the 2SD1880, about 88.9 KB, listed as a schematic but named after a single semiconductor part.

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.

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.

Catalogued as a schematic, the 40.9 KB PDF 2SD2413 with an E tag relates, by the JIS 2SD prefix, to an NPN bipolar transistor rather than a complete board.

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