COMSET BC179B

PNP BC177 – BC178 – BC179
LOW NOISE GENERAL PURPOSE AUDIO AMPLIFIERS
The BC177,BC178 and BC179 are silicon planar epitaxial PNP transistors mounted in TO-18
metal package.
They are suitable for use in drive audio stages, low-noise input audio stages and as low power,
high gain general purpose transistors.
Compliance to RoHS.
