PDF datasheet, 40.9 KB, for the 2SD2240 transistor, filed under schematics in this index. An _E suffix in the name is an edition marker for the document only. In JIS terms 2SD is the code for NPN low-frequency bipolar transistors, and the body marking may read simply D2240. The sheet helps verify the pinout and the voltage, current and power limits before swapping the part, and the gain rank letter printed on the original is worth matching where possible.
