2SD2703 is a general purpose amplification transistor launched by ROHM, its features are large current amplification factor and low saturation voltage.
The 2SD2703 is a general‑purpose N‑PN transistor designed for low‑frequency amplification with a large collector current capability and low collector‑saturation voltage. It is suitable for a wide range of electronic circuits such as audio‑visual equipment, office‑automation devices, and communication gear.
The document lists absolute maximum ratings, electrical characteristics, and packaging specifications, including breakdown voltages, current gain, transition frequency, and capacitance curves. An appendix notes usage restrictions for safety‑critical applications and export control information.
| Collector‑base breakdown voltage (BVCBO) | 30 V |
|---|---|
| Transition frequency (fT) | 100 MHz |
| DC current gain (hFE) | up to 320 |
The typical transition frequency is 100 MHz.
The saturation voltage is ≤ 350 mV at IC = 500 mA and IB = 25 mA.
