PDF sheet named BQ24728, a Texas Instruments notebook charge controller part number, at 94.3 KB.

Schematic in PDF, about 420 KB, named only SEM2105, so the name does not identify a laptop model or board number.

PDF reference document named TPS4202, around 1 MB. The name gives only a part designation with no device or board, so it is most likely a datasheet or application…

Datasheet-style PDF for the AO4601, filed here as a schematic, 686 KB. The part number matches an Alpha and Omega Semiconductor dual MOSFET in an SO-8 package combining…

Small 91.1 KB PDF named sn608098, filed as a schematic. The name does not reveal the device; it may be a Texas Instruments component number, though that cannot be…

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.

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…

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.

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…

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

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 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.

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.

PDF of 119 KB for the 2SD1664, written in lowercase in the original name and filed as a schematic.

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

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…

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.

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.

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

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.

The 2SK3413LS is documented in this compact 32.2 KB PDF, indexed as a schematic but effectively a component datasheet.

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

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

The 2SK3291 transistor is the subject of this 34.2 KB PDF, filed as a schematic although it works as a datasheet.

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…

The name of this 421 KB PDF carries just one token, 2SK2836, a JIS-format number for an N-channel FET.

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…
