SGS Thomson Microelectronics BCY59, BCY58 Datasheet
DESCRI PTIO N
The BCY58and BCY59are silicon planar epitaxial
NPN transistorsin Jedec TO-18 metal case.
They are intended for use in audio input stages,
driverstagesand low-noise inputstages.The complementary PNP types are respectively the BCY78
and BCY79.
