VHF power MOS transistor

Silicon N-channel enhancement mode vertical D-MOS transistor encapsulated in a 6-lead, SOT119A 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 associated Data Handbook for further information.

Features and benefits

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

Applications

  • Linear amplifier applications in television transmitters and transposers
