VHF push-pull power MOS transistor
FEATURES
•
High power gain
•
Easy power control
•
Good thermal stability
•
Gold metallization ensures
excellent reliability.
DESCRIPTION
Dual push-pull silicon N-channel
enhancement mode vertical D-MOS
transistor, designed for broadcast
transmitter applications in the VHF
frequency range.
The transistor is encapsulated in a
4-lead SOT262A1 balanced flange
package, with two ceramic caps. The
mounting flange provides the
common source connection for the
transistors.
