This document provides technical specifications for the Siemens BC 556, BC 557, BC 558, BC 559, and BC 560 series of epitaxial PNP silicon planar transistors. These components are housed in TO 92 plastic packages and are designed for use in AF input and driver stages, with specific models like the BC 559 and BC 560 noted for low-noise input applications. They are also intended to serve as complementary transistors to the BC 546, BC 547, BC 648, BC 549, and BC 550 series.
