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

The name 2sd1455 refers to a JIS-registered NPN transistor, and this 53.0 KB PDF is most likely its manufacturer datasheet, although the index lists it as a schematic.

A fairly detailed 200 KB PDF for the 2SD2352, a JIS-numbered NPN transistor, where the 2SD prefix denotes NPN low-frequency parts.

A 135 KB PDF covering the 2SK2711 transistor. The extra 1-5 token in the name is not explained and may point to a page range or document revision.

Compact 33.0 KB PDF on the 2SK1834 transistor. The 2SK prefix belongs to the Japanese JIS designation system and means an N-channel field-effect device, so the content…

The name 2SK1446LS marks this 32 KB PDF as covering an LS-suffixed version of the 2SK1446.

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

Datasheet-style PDF for the 2SK669, a part number in the JIS 2SK series used for N-channel field-effect transistors, listed in the index as a schematic.

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…

The 2SC4163 part number is all this 98.9 KB PDF name reveals, so although labelled a schematic it is best read as a transistor datasheet.

Small 95.8 KB PDF for the 2SC4109, indexed with the schematics. The file name gives nothing beyond the part number; the 2SC prefix identifies an NPN bipolar transistor…

Datasheet-sized PDF of 38.0 KB for the 2SC5474, with an _E suffix in the name that likely marks an English edition; that reading is an inference.

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…

For the 2SC4006 there is this 79.6 KB PDF, filed as a schematic though a bare JIS code like this normally names a datasheet.

Named for the 2SC4003, this 79.4 KB PDF is listed as a schematic but appears to be a transistor datasheet.

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

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…

The 2SB1642 PNP transistor is documented in this 181 KB PDF, listed as a schematic though it is a part datasheet.

Component data for the 2SB1527 in PDF form, roughly 73 KB, catalogued as a schematic though the bare part number suggests a datasheet.

Covering the 2SA1433, this 78.1 KB PDF is indexed as a schematic but is most likely a component data sheet.

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.

Data sheet sized PDF of 45.9 KB named 2PC4617J, revision 2 judging by the suffix. The J suffix normally separates a package or variant from the base 2PC4617 part, which…

The 2N4126 is the subject of this 81.9 KB PDF, listed in the schematic section of the catalogue but almost certainly a single-part datasheet.

Compact datasheet, 14.5 KB in PDF form, for the part numbered 2N2955 according to the file name.

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

Listed as a schematic, this 68.8 KB document carries the name 1SS378 and nothing else, pointing to a component data sheet for a small-signal silicon diode under the JIS…

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

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…

Listed as a schematic, this compact 47.4 KB PDF is named 80CLQ150, a code that resembles a power semiconductor part number rather than a board number.

Filed as a schematic, this 160 KB PDF carries the bare code 409CNQ135 with no brand, model or revision attached.

A small 56 KB PDF filed under schematics, named only 40CPQ080. The name looks like a component part code, not a motherboard number, and it states no device, brand or…

Indexed as a schematic, the 75.3 KB PDF titled 30TPS appears to be a family datasheet for a series of power semiconductors sharing that prefix, rather than a circuit…

Named 28F102, this 116 KB PDF is filed as a schematic but the code points to a 28F-family parallel flash memory device rather than a board.

PDF of 55.5 KB titled 30CPQ035, a code following discrete semiconductor numbering, so it is best treated as a datasheet despite the schematic label.

Combined datasheet PDF of 163 KB covering the 24C01B and 24C02B, serial EEPROMs of 1 Kbit (128 bytes) and 2 Kbit (256 bytes) respectively on the I2C bus.

Datasheet in PDF form for the 24AA024, 24LC024, 24AA025 and 24LC025 serial EEPROMs, 2 Kbit I2C memories grouped in one document.

PDF datasheet of 338 KB covering the 24AA01 and 24LC01B, the 1 Kbit members of this I2C serial EEPROM line.

Filed as a schematic, this 134 KB PDF is named for the 9AF40 and 9AF60 parts, two variants in one document.
