Circuit schematic for the ASUS K53U built on the Compal LA-7322P motherboard, revision 1.0, in PDF form.

PDF reference sheet of 127 KB for the 2SD2219 transistor, catalogued among schematics although it documents one component. The name holds just the part number.

Reference sheet for the 2SD2385 transistor, delivered as a 180 KB PDF and indexed under schematics.

At 443 KB, this is the largest PDF in the group, covering the 2SK1544 transistor, likely with more curves or drawings.

Datasheet-type document in PDF for the 2SA1687, a Japanese JIS-registered transistor, listed under schematics at 143 KB.

The 2SA1739 is named in this 44.6 KB PDF, listed among schematics although the JIS 2SA designation shows it is a PNP bipolar transistor datasheet.

Stored under schematics, this 171 KB PDF is named 2SD1407A and is most probably the datasheet for that transistor variant, the A suffix distinguishing it from the base…

NEC datasheet in PDF form for the 2SK1584, 57.9 KB, with the manufacturer given directly in the file name.

Reference PDF for the 2SA1469, 101 KB, filed under schematics. Japanese JIS numbering uses 2SA for PNP transistors oriented toward high-frequency applications, which…

Datasheet PDF for the 2SA2062 transistor, 29.9 KB, the same size as the neighbouring 2SA2063 file, which hints at a shared document layout.

A 277 KB PDF covering the 2SD2539, a part number in the JIS 2SD family, which denotes NPN bipolar transistors for low-frequency circuits.

Filed among schematics, this 467 KB PDF carries just the transistor number 2SC4320 and should be regarded as its datasheet.

The 102 KB PDF 2SC5041 is indexed under schematics, though its name is just a 2SC part number, the Japanese JIS code for an NPN bipolar transistor, so treat it as a…

The 2SC3938 sheet arrives as a 46.3 KB PDF with an _E suffix, which on Japanese component documents typically signals an English edition.

Listed as a schematic, this 118 KB PDF is named only 2SC4863 and is most likely a component datasheet.
