DESCRIPTION
The 2SC4095 is an NPN epitaxial silicon transistor designed for use in
low-noise and small signal amplifiers from VHF band to UHF band.
2SC4095 features excellent power gain with very low-noise figures.
2SC4095 employs direct nitiride passivated base surface process (DNP
process) which is an NEC proprietary new fabrication technique which
provides excellent noise figures at high current values. This allows
excellent associated gain and very wide dynamic range.
