10/5Pcs Original C2073 2SC2073 A940 2SA940 TO-220 Power Transistors for Audio Amplifiers
Product Description:
The C2073 (2SC2073, NPN) and A940 (2SA940, PNP) are high-voltage complementary power transistors in TO-220 packaging, designed for high-current switching and linear amplification. This matched pair delivers robust performance in audio systems, industrial controls, and power conversion circuits, with exceptional thermal stability and low saturation voltage.
Key Features:
Complementary Pair:
2SC2073 (NPN): 150V / 1.5A / 25W, ideal for push-pull amplifier outputs.
2SA940 (PNP): -150V / -1.5A / 25W, perfect for symmetrical power stages.
High Voltage Tolerance: Supports up to 150V for demanding industrial and audio applications.
Applications:
Hi-Fi audio amplifiers (Class AB/B) and subwoofer drivers
Switch-mode power supplies (SMPS) and voltage regulators
Motor control circuits (DC motor drivers, servo systems)
Industrial welding equipment and UPS inverters
DIY electronics (guitar effect pedals, LED dimmers)
