VHF push-pull power MOS transistor

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.

Features and benefits

  • High power gain
  • Easy power control
  • Good thermal stability
  • Gold metallization ensures excellent reliability

Applications

  • Large signal amplifier applications in the VHF frequency range
