Specifications:

The 2SC2223 transistor typically has a collector-emitter voltage (VCEO) rating of 50V and a collector current (IC) rating of 150mA. The current gain (hFE) is typically between 100 and 400. The transition frequency (fT) is typically around 180 MHz. The saturation voltage (VCE(sat)) is usually less than 0.3V. It comes in a small SOT-23 or similar surface-mount package. It's designed for low-power applications. The transistor's high hFE allows for efficient amplification of small signals. The low saturation voltage minimizes power dissipation in switching applications. It is suitable for use in both analog and digital circuits. The transistor is often used in pre-amplifier stages. The operating temperature range is typically from -55°C to +150°C. The specific hFE range and other parameters should be confirmed from the manufacturer's datasheet for the specific part number suffix (e.g., -T1B-A/JM).
