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

PDF of 154 KB for the 2SD2202, listed as a schematic but named like a transistor datasheet.

PDF reference sheet covering the 2SA1823, 92.1 KB, listed among schematic files. The 2SA part prefix indicates a PNP bipolar transistor in the JIS registration system.

PDF, 502 KB, identified by the transistor number 2SC2668 and placed in the schematic category, though it is presumably a datasheet.

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.

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…
