Product Description

The 2SA1661 is a PNP bipolar junction transistor designed for general-purpose amplification and switching applications. With a maximum collector-emitter voltage (VCEO) of -50V and a continuous collector current (IC) of -1.5A, it operates within a temperature range of -55°C to +150°C. Commonly used in industrial power management, audio amplifiers, and motor control systems, this transistor features moderate gain and low saturation voltage. The 2SA1661 datasheet specifies its pin configuration and thermal characteristics, while compatible 2SA1661 equivalent transistors include 2SA1837 or 2SA1309. Key 2SA1661 PNP specifications emphasize its TO-92L package and compatibility with medium-power circuits, though it requires careful heat dissipation in high-current scenarios. It lacks built-in communication interfaces or direct module integration, focusing instead on discrete component functionality.
