2N1711
EPITAXIAL PLANAR NPN
DESCRIPTION
The 2N1711 is a silicon Planar Epitaxial NPN
transistor in Jedec TO-39 metal case. It is
intented for use in high performance amplifier,
oscillator and switching circuits.
The 2N1711 is also used to advantage in
amplifiers where low noise is an important factor.
