A940 PDF Specs and Replacement
The A940 is a PNP bipolar junction transistor commonly used in low-frequency and medium-power amplification stages. It features a collector-emitter voltage rating of 150V and a continuous collector current up to 1.5A, making it suitable for audio drivers and general signal processing. Its power dissipation is typically around 25W. The device offers moderate gain (hFE 40-140) with low noise, ensuring stable linear performance. Housed in a TO126 package, the A940 provides reliable thermal behavior and is frequently paired with complementary NPN devices (such as C2073) in push-pull amplifier designs.
