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 com-
plementary PNP types are respectively the BCY78
and BCY79.
