  • High hFE and low VCEsat at high current operation
  • High collector current capability: IC maximum 5 A
  • Higher efficiency leading to less heat generation.
  • AEC-Q101 qualified

Target applications

  • Medium power peripheral drivers, e.g. fans and motors
  • Strobe flash units for DSC and mobile phones
  • Inverter applications, e.g. TFT displays
  • Power switch for LAN and ADSL systems
  • Medium power DC-to-DC conversion
  • Battery chargers.
