BC337 and BC338 Vishay Semiconductors formerly General Semiconductor Small Signal Transistors (NPN) TO-226AA (TO-92) Features NPN Silicon Epitaxial Planar Transistors for switching 0.142 (3.6) 0.181 (4.6) and amplifier applications. Especially suited for AF-driver stages and low power output stages. These types are also available subdivided into three groups -16, -25, and -40, according to their DC current gain. As complementary types, the PNP transistors BC327 and BC328 are recommended. On special request, this transistor is also manufactured in the pin configuration TO-18.
