PDF file, 105 KB, for the 2SD2199, placed under the schematic category although the name indicates a discrete transistor datasheet.

A larger 213 KB PDF named 2SD1415A, listed under schematics but realistically the datasheet for that transistor; the A suffix denotes a variant of the base 2SD1415 part.

Schematic set for the Lenovo ThinkPad X1 Carbon, packed in a RAR archive of about 1 MB.

Here is the 2SD1825 in PDF format, 150 KB, listed under schematics though the name suggests a transistor datasheet rather than a circuit diagram.

This 55 KB PDF relates to the 2SC2362K, a K-suffixed NPN transistor named under the JIS convention.

Short 46 KB PDF named only 2SD1651, classified as a schematic but almost certainly the datasheet for this NPN bipolar transistor from the 2SD family.

Reference PDF, 170 KB, for the 2SD1525 transistor, listed under schematics. Japanese JIS designation 2SD identifies an NPN bipolar device meant for low-frequency work.

The 2SJ106 is the only detail in this 283 KB PDF name. JIS numbering reserves 2SJ for P-channel field-effect transistors, so the document is best treated as a datasheet…

PDF file, 105 KB, for the 2SC4695 part. Since 2SC is the JIS designation for NPN bipolar transistors, the document is likely the component datasheet rather than a device…

Part datasheet for the 2SC4484, a 134 KB PDF. Japanese JIS numbering uses 2SC for NPN bipolar transistors, which identifies the device class here; nothing else is given…

Datasheet-like PDF of 116 KB covering the 2SC3638. Under JIS semiconductor naming, 2SC identifies NPN bipolar transistors.
