PDF reference for the 2SD200, a part from the 2SD range of NPN bipolar transistors, indexed as a schematic but probably a datasheet; the name states nothing beyond the…

Datasheet for the 2SD1835 NPN bipolar transistor, stored as a 149 KB PDF in the schematic category. The 2SD prefix marks NPN transistors under the Japanese JIS standard.

Documentation for the 2SD2241 NPN transistor, supplied as a 178 KB PDF and categorised as a schematic. The name provides only the part number.

A 43.9 KB PDF for the 2SD2580, indexed as a schematic. Japanese JIS numbering reserves the 2SD prefix for NPN bipolar transistors in low-frequency applications, so this…

Small PDF of 26.5 KB named 5HP01SS, listed as a schematic yet evidently referring to a single semiconductor part rather than a board.

The 2SD1800 transistor is covered by this 79 KB PDF datasheet. Under JIS numbering, 2SD denotes an NPN transistor for low-frequency service, often used in switching…
