FEATURES
DESCRIPTION
Silicon N-channel enhancement
mode vertical D-MOS transistor
designed for large signal amplifier
applications in the VHF frequency
range.
The transistor is encapsulated in a
4-lead SOT123A flange package,
with a ceramic cap. All leads are
isolated from the flange.
Matched gate-source voltage (V
groups are available on request.
