DESCRIPTION
The 2SC4094 is an NPN epitaxial silicon transistor designed for use in
low-noise and small signal amplifiers from VHF band to UHF band. Low-
noise figure, high gain, and high current capability achieve a very wide
dynamic range and excellent linearity. This achieved by direct nitride
passivated base surface process (DNP process) which is an NEC
proprietary new fabrication technique.
