High Frequency NPN Transistor Array
The CA3127 consists of five general purpose silicon NPN
transistors on a common monolithic substrate. Each of the
completely isolated transistors exhibits low 1/f noise and a
value of f
T
in excess of 1GHz, making the CA3127 useful
from DC to 500MHz. Access is provided to each of the
terminals for the individual transistors and a separate
substrate connection has been provided for maximum
application flexibility. The monolithic construction of the
CA3127 provides close electrical and thermal matching of
the five transistors.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
compatible with both SnPb and Pb-free soldering operations. Intersil
Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-020.
