FEATURES
DESCRIPTION
Dual push-pull 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, SOT279A balanced flange
package, with a ceramic cap. The
mounting flange provides the
common source connection for the
transistors.
