2SD2707 / 2SD2654 / 2SD2351 / 2SD2226K / 2SD2227S are general purpose transistors produced by ROHM. They have high DC current gain, high emitter-base voltage and low saturation voltage.
The document provides specifications for a family of general‑purpose NPN transistors (2SD2707, 2SD2654, 2SD2351, 2SD2226K, 2SD2227S). Key features include high DC current gain, high emitter‑base voltage (Vebo = 12 V) and low saturation voltage (typical Vce(sat) = 0.3 V at Ic = 50 mA).\n\nAbsolute maximum ratings, packaging details (SMT3, SPT, etc.), and extensive electrical characteristics such as breakdown voltages, current limits, and transition frequency are listed. The appendix contains legal notices and export‑control information.
