| BCY58 BCY59 LOW NOISE AUDIO AMPLIFIERS DESCRIPTION The BCY58 and BCY59 are silicon planar epitaxial NPN transistors in Jedec TO-18 metal case. They are intended for use in audio input stages, driver stages and low-noise input stages. The complementary PNP types are respectively the BCY78 and BCY79.
