ST 8050 NPN Silicon Epitaxial Planar Transistor for switching and amplifier applications. Especially suitable for AF-driver stages and low power output stages. The transistor is subdivided into four groups, B, C, D and E, according to its DC current gain. As complementary type the PNP transistor ST 8550 is recommended. On special request, these transistors can be manufactured in different pin configurations.
