2SA1837 Specs and Replacement

The 2SA1837 is a high-voltage PNP bipolar junction transistor widely used in audio power amplifiers and voltage-amplification stages. It features a collector-emitter voltage rating of 230V, a continuous collector current of 1A, and low output capacitance, making it suitable for high-fidelity designs. Its fast switching characteristics and linear gain improve stability in driver stages. The 2SA1837 is often paired with the complementary 2SC4793 to form robust push-pull amplifier configurations.
