PNP Silicon Transistor
BC 201, BC 202, and BC 203 are epitaxial PNP silicon planar transistors of miniature design in U 32 plastic package. The types are marked by a green (BC 201), blue (BC 202), and gray (BC 203) color line on the case. The transistors are aprticularly intended for use in low noise AF amplifiers and as complementary transistors to BC 121, BC 122, and BC 123.
