VHF power MOS transistor

Silicon N-channel enhancement mode vertical D-MOS transistor encapsulated in a 4-lead, SOT121B flange package with a ceramic cap. All leads are isolated from the flange. A marking code, showing gate-source voltage (VGS) information is provided for matched pair applications. Refer to the “General” section of the handbook for further information.

Features and benefits

  • High power gain
  • Low intermodulation distortion
  • Easy power control
  • Good thermal stability
  • Withstands full load mismatch

Applications

  • Industrial and military applications in the HF/VHF frequency range.
