Product Description

The 2SA1774 is a high-performance PNP transistor designed for general-purpose amplification and switching applications. As a 2SA1774 PNP transistor, it operates within a voltage range of -5V to -50V, making it suitable for low-to-medium power amplifier circuits, such as the 2SA1774 amplifier circuit in audio systems or signal processing modules. Its collector current capacity of -1.5A and power dissipation up to 10W enable direct integration with voltage regulators, relays, or small motor drivers. The device supports operation across a temperature range of -55°C to 150°C, ideal for industrial automation, automotive electronics, and power supply units. Key advantages include low saturation voltage (VCE(sat) ≈ -1.2V at IC = -1A) and high current gain (hFE ≈ 60-320), though its moderate switching speed limits high-frequency applications. While not equipped with communication interfaces or screen components, its compact TO-220 package ensures efficient thermal management in space-constrained designs.
