Description
The 2SA940 (A940) is a PNP medium-power bipolar junction transistor (BJT) commonly used in audio amplifier circuits, power amplifiers, voltage regulators, and driver stages. It is especially popular in Class-AB audio amplifiers where it is often paired with the 2SC2073 (C2073) transistor. Because of its good voltage handling capability, high gain, and reliable performance, the A940 is widely used in DIY amplifier projects and commercial audio equipment.
