NEC's NE680 series of NPN epitaxial silicon transistors is
designed for low noise, high gain and low cost applications.
Both the chip and micro-x versions are suitable for applications
up to 6 GHz. The NE680 die is also available in six different low
cost plastic surface mount package styles. The NE680's high
f
T
makes it ideal for low voltage/low current applications, down
to as low as 0.5 V / 0.5 mA. IC max for the NE680 series is
35 mA. For higher current applications see the NE681 series.
