FEATURES
Silicon Epitaxial Planar Transistors switching amplifier applications. These transistors subdivided into three groups according their current gain. type BC556 available groups however, types BC557 BC558 supplied three groups. BC559 low-noise type available three groups. complementary types, transistors BC546 BC549 recommended. special request, these transistors also manufactured configuration TO-18.
