COMSET SEMICONDUCTORS

1/3

The BC107, BC108 and BC109 are silicon planar epitaxial NPN 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.

The complementary PNP are BC177, BC178 and BC179.

Compliance to RoHS.
