Fourth chapter of a Spanish cellular-phone course, dealing with cloning or unlocking, saved as an 863 KB PDF.

Schematic in PDF, 1.96 MB, centred on the SM7150 processor according to its name; the phone model and board revision are not stated.

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

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

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.

Part number 2SC4207 is the sole content of this 257 KB PDF's name, which the index places under schematics.

Part-number PDF for the 2SC4107, 93.2 KB, stored in the schematic category. Nothing in the name points to a specific device or board; the 2SC prefix marks an NPN bipolar…

PDF sheet titled only with the part number 2SC5022, 42.0 KB, placed under schematics. No suffix, revision or maker appears in the name.

A 99.4 KB PDF for the 2SC3779 transistor. The file name gives only the part number; the 2SC prefix follows the Japanese JIS scheme for NPN transistors, so this is almost…

Datasheet for the 2SC3613, a 241 KB PDF listed among schematic files although its content is a single-component specification.

A 144 KB PDF for the 2SA1317 transistor, listed under schematics but almost certainly a part datasheet given that the name is just the component code.

Component documentation for the 2SA1892, supplied as a 225 KB PDF. Under Japanese JIS naming, 2SA marks a PNP bipolar transistor, so despite being classed as a schematic…

PDF document for the Samsung SM-A105FN, the Galaxy A10 European variant, inside a 922 KB RAR archive.

Only the part number 2SD2088 appears in the name of this 171 KB PDF, so treat it as the datasheet for that transistor.

Datasheet in PDF form for the 2SK2058, a part number in the Japanese JIS 2SK series, which designates N-channel field-effect transistors.

Brief 31.8 KB PDF for the 2SK1980, which by the JIS 2SK prefix is an N-channel FET. Although indexed as a schematic, the document is almost certainly a datasheet for…

The 2SK1900 transistor is the subject of this 99.3 KB PDF, catalogued with schematics. Under the JIS convention, 2SK designates an N-channel field-effect transistor, so…

The 2SK1736 is documented in this 92.6 KB PDF. Under JIS designations, 2SK means an N-channel FET, so the file is almost certainly a component datasheet despite its…

Part 2SK1438 is the subject of this 108 KB PDF, filed in the index as a schematic but almost certainly a component datasheet.

Component documentation for the 2SK1119, a part number in the Japanese 2SK series that designates N-channel field-effect transistors.

PDF document for the 2SK715 part number, catalogued under schematics but almost certainly a component datasheet, since the 2SK prefix follows the Japanese JIS…

Labelled only 2SJ254, this 93.0 KB PDF is filed as a schematic but almost certainly describes one discrete component: the 2SJ prefix in the JIS system denotes a…

The 2SD1244 with an _E suffix is the subject of this 44.8 KB PDF, placed in the schematic category.

The 2SC4249 transistor is the subject of this 263 KB PDF, filed under schematics. The name carries the part number alone, so maker and revision are not stated.

The 2SC4935 is covered by this 176 KB PDF, filed as a schematic but, judging by the bare JIS part number, almost certainly the transistor datasheet.

An 88.2 KB PDF carrying only the designation 2SC3402, catalogued as a schematic but almost certainly a single-part reference sheet.

Document for the 2SA1619 in PDF form, 51.3 KB, catalogued under schematics though it concerns a single transistor.

The 2SA1539 part number gives this 41.0 KB PDF its name, and although it is filed under schematics it almost certainly holds the datasheet for that transistor.

Indexed as a schematic, this 50.3 KB PDF is titled 1N757A, a JEDEC 1N diode number with A suffix, so it almost certainly holds a part datasheet.

Filed as a schematic, the 209CNQ135 document is almost certainly a datasheet for a high-current Schottky rectifier module in the CNQ series, where 135 points to a 135 V…

Filed as a schematic, this 161 KB PDF titled 27lc010 is almost certainly a component datasheet rather than a board diagram.

Quanta ED2 motherboard schematic, UMA edition, version 1C and revision C2A, provided as a roughly 1007 KB PDF.

PDF schematic for the ASUS X409 series, with the name listing the X409FA, X409FB, X409FJ and X409FL variants that share this design.

Schematic for the Apple iPad 2 logic board, saved as a 637 KB PDF. Repair technicians use such drawings to trace supply rails, check the charging and battery circuits…

Compal LS-8481P schematic in a 52.9 KB RAR archive. Unlike its siblings, the name states no revision, and no laptop model is mentioned either.

PDF schematic for the Lenovo ThinkPad W700 DDR3 variant, about 2.21 MB, with an added note in the name reading N-note 07247 4Y90 whose meaning is not certain; it may be…

Named for the 2SK2824 transistor, this 305 KB PDF is indexed as a schematic but is most likely a single-part datasheet.

A 418 KB PDF named for the 2SK2742, an N-channel field-effect transistor under the Japanese JIS 2SK prefix, placed in the schematic category.

A 134 KB PDF for the 2SK2460N, catalogued as a schematic but almost certainly a datasheet for a discrete transistor, since 2SK numbers under the Japanese JIS system…
