Product Description
Product Overview
The TOSHIBA 2SC4944 is a silicon NPN epitaxial transistor utilizing the PCT process. It is designed for audio frequency general-purpose amplifier applications. Key features include a small package (dual type), high voltage and current capabilities (VCEO = 50 V, IC = 150 mA max), high hFE (120 to 400), and excellent hFE linearity. It is complementary to the 2SA1873.
