EMG2 / UMG2N / FMG2A is an NPN 100mA 50V complex digital transistor produced by ROHM Co., Ltd. It features built-in bias resistors and is suitable for inverter circuits, interface circuits, and driver circuits.
The EMG2, UMG2N, and FMG2A are NPN transistors that incorporate built‑in bias resistors (Ry = Re = 47 kΩ) and are offered in compact SOT‑353 (SC‑88A) or SC‑74A packages. They are designed for inverter, interface, and driver circuits, providing easy on/off control and eliminating the need for external bias resistors.
The datasheet lists absolute maximum ratings, electrical characteristics such as a 50 V supply rating, 30 mA output current, and up to 100 mA collector current, as well as power dissipation limits (150 mW for EMG2/UMG2N, 300 mW for FMG2A). Detailed dimension tables for each package and application circuit examples are also provided.
