HF-VHF power MOS transistor

Silicon N-channel enhancement mode vertical D-MOS transistor designed for professional transmitter applications in the HF/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.

Features and benefits

  • High power gain
  • Low noise
  • Easy power control
  • Good thermal stability
  • Withstands full load mismatch
  • Gold metallization ensures excellent reliability

Applications

  • Transmitter applications in the HF/VHF frequency range
