  • SOT89 (SC-62) package
  • Low collector-emitter saturation voltage VCEsat
  • High collector current capability: IC and ICM
  • Higher efficiency leading to less heat generation
  • Reduced printed-circuit board requirements
  • AEC-Q101 qualified

Target applications

  • Power management
    • DC/DC converters
    • Supply line switching
    • Battery charger
    • LCD backlighting
  • Peripheral drivers
    • Driver in low supply voltage applications (e.g. lamps and LEDs)
    • Inductive load driver (e.g. relays, buzzers and motors)
