Repair guide for the G750JH gaming notebook, RG in the name, in a 999 KB PDF. Such guides typically show the mainboard with highlighted parts, expected voltages at test…

PDF reference on the 2SC4517 transistor, the name noting it as NPN; the file is 26.9 KB and indexed as a schematic.

The 3N258 is the subject of this 42.2 KB PDF, indexed as a schematic but in practice a component reference.

PDF document for the 2SK2775, filed under schematics although the part number points to a component datasheet rather than a board drawing.

The 2SK2750 is covered by this 394 KB PDF, indexed as a schematic but most likely the component datasheet, since 2SK is the JIS prefix for N-channel FETs.

Datasheet-style PDF for the 2SK1412LS, a Japanese 2SK-series N-channel field-effect transistor, filed in the index under schematics.

Indexed as a schematic, the 44.5 KB PDF named 2SD1328_E should be a datasheet for the 2SD1328, which the JIS 2SD prefix identifies as an NPN bipolar transistor for…

The name 2SC4172 is a Japanese JIS semiconductor designation, so this 109 KB PDF, though filed as a schematic, should be the reference sheet for an NPN bipolar…

Stored under schematics, this 93.8 KB PDF is named for the 2SC4123 and is expected to hold the transistor's datasheet rather than a circuit drawing.

Small PDF of 25.0 KB dedicated to the 2SC4064, catalogued as a schematic. Going by JIS semiconductor numbering, 2SC marks an NPN bipolar transistor; the name gives no…

The 2SC3606 is the only detail given by this 464 KB PDF, catalogued as a schematic yet functionally a part datasheet.

Covering the 2SC3599, this 124 KB PDF is a discrete transistor datasheet even though it is filed as a schematic.

Datasheet-style PDF of 87.7 KB labelled 2SC3400, listed in the schematic section of the index.

The 2SC5323 is the only clue in this file name, so treat this 122 KB PDF as a probable transistor datasheet even though it sits in the schematic category.

Filed under schematics, this 49.7 KB PDF covers the 2SC1318A, an NPN transistor in JIS numbering; the A suffix denotes a variant of the base 2SC1318 type, often with…

At 190 KB this PDF is larger than most entries here and is named for the 2SC982, an NPN transistor according to the JIS 2SC prefix; the TM suffix in the name is not…

Catalogued among schematics, this 54.5 KB PDF is named for the 2SB642, which the JIS 2SB prefix marks as a PNP transistor; the document is therefore expected to be a…

A 54.3 KB PDF, named in lowercase, for the 2SA1862 PNP bipolar transistor of the JIS 2SA series.

Datasheet for the 2SA879 in a 49.9 KB PDF; the trailing _E in the name probably denotes an English version, though the name does not confirm it.

Short PDF of only 19.4 KB covering the 1SV298H, the H suffix marking a variant of the base 1SV298 part.

Filed as a schematic, this 65.8 KB PDF takes its name from the 1SV246 part number and carries no other details.

Named purely after 1SS322, this 73.1 KB PDF does not identify any device, board or revision.

Filed as a schematic, this 70.6 KB PDF is named only with the code 1SS319 and gives no device context.

The name 251UL80S is a manufacturer part code rather than a board number, so this 143 KB PDF is likely a power semiconductor datasheet even though it is listed as a…

The name 243NQ gives only a part family prefix with no suffix, so this 45.4 KB PDF probably covers a whole series of power rectifier devices in one datasheet, despite…

PDF datasheet for the 93C75A serial EEPROM, part of the 93-series three-wire Microwire memory family, filed under schematics with a size of 395 KB.

PDF listed as a schematic for the 28F020, with Intel named as the manufacturer in the file name. The 28F020 is a 2 Mbit parallel flash memory part.

PDF document of 202 KB named 25CTQ, a series-style code with no voltage suffix, so it probably covers a family of related components in datasheet form.

Weighing 332 KB, this PDF is titled 25C160, a name that resembles a serial memory part code, so treat it as a chip datasheet rather than a motherboard schematic.

Datasheet PDF, 83.7 KB, for the 24C01 serial EEPROM, a 1 Kbit (128-byte) memory on the two-wire I2C bus. The name gives no device or board context.

Front camera circuit from the Samsung SM-A10 schematic, a 2.25 MB PDF. It lays out the selfie camera connector, data and clock lanes, control signals and the voltages…

PDF schematic for the ASUS E402SA motherboard at revision 2.1, 848 KB. It shows the power tree, standby and main rails, charging circuitry, memory and peripheral…

Schematic PDF for a Dell 15-inch DDR4 laptop motherboard, board number 223032-1, model not stated. The pattern points to Wistron, which designs many Dell boards.
