PCB artwork for the subwoofer 7294 design, version 1.1, in a 72.5 KB PDF. The Polish word oddruku in the name indicates a print-ready layout, meant for toner transfer or…

PCB layout drawing for the Honor Play, a Huawei sub-brand phone, in a 957 KB PDF. Layout documents show component placement and designators on the board, so a technician…

Hi-fi 2.1 amplifier schematic credited to SeahorseDIY, in a 688 KB PDF. It covers a stereo-plus-subwoofer layout, likely with the crossover or filter stage feeding the…

The 2SA1518 is the subject of this 30.2 KB PDF, which the index files as a schematic although the name suggests a component data sheet.

Component location map for the small sub-board of the Redmi K40 Pro smartphone, provided as a 95.4 KB PDF.

Reference sheet of 37.8 KB covering the 2SC5694, an NPN bipolar transistor going by the JIS 2SC prefix, filed under schematics but most likely a datasheet.

PDF document named TDA2824, a designation used for a dual low-voltage audio power amplifier IC.

Datasheet in PDF format, 229 KB, for the 2SD553 transistor, catalogued among schematics. Nothing besides the part type is stated in the name.

A 171 KB PDF for the 2SC5196 transistor, grouped under schematics although the name points to a datasheet.

A 100 KB PDF for the 2SC4769, categorised as a schematic, though the name is just a JIS part number and the content is therefore most likely a datasheet.

Datasheet covering the 2SC4487 transistor, stored as a 155 KB PDF and filed as a schematic in the index.

A 40.7 KB PDF bearing the 2SC5451 part number. Under the JIS 2SC convention it is an NPN bipolar transistor, and the document is probably its datasheet even though the…

Datasheet-style PDF of 304 KB for the 2SC5716, a JIS-numbered NPN bipolar transistor, catalogued here as a schematic.

The 2SA1483 is covered by this 178 KB PDF, catalogued under schematics though the name suggests a component data sheet.

Catalogued as a schematic, the 44.6 KB PDF 2SA1973 is named after a JIS-numbered PNP bipolar transistor, identified by the 2SA prefix.

PDF of 126 KB covering the 2SD1842, an NPN bipolar transistor in the JIS 2SD series, so the content is a datasheet rather than a board schematic.

PDF document of 112 KB for the 2SD2280, an NPN bipolar transistor in the Japanese 2SD numbering, filed as a schematic but in practice a datasheet.

The 2SK1413 is documented in this 112 KB PDF, listed under schematics but named after a single discrete part, which points to a datasheet.

The largest of this group at 340 KB, this PDF for the 2SC5446 likely contains an extensive datasheet with many characteristic curves and detailed package drawings.

Indexed as a schematic, this 175 KB PDF is named 80EPF10, a code following International Rectifier style for a rectifier diode part rather than a board number.

Small PDF, 33.9 KB, covering the 2SK1036 N-channel field-effect transistor from the JIS 2SK range.

Datasheet in PDF format, 90.9 KB, for the 2SC4522 NPN bipolar transistor, the 2SC prefix being the JIS designation for that device class.

Part 2SC5443 is the only detail this 42.3 KB PDF name provides. The 2SC prefix marks a JIS-registered NPN bipolar transistor, so expect a datasheet with electrical…

Reference PDF of 38.3 KB for the 2SC2632, with an _E suffix that possibly marks an English version, though this is not confirmed.

The largest file in this batch at 308 KB, this PDF documents the 2SA1384, a JIS-numbered component whose 2SA prefix identifies a PNP transistor of the high-frequency…

PDF of 87.3 KB named after the 2SA1347 transistor and nothing else, so it is best regarded as a datasheet despite the schematic label.
