Features and benefits

  • Low collector-emitter saturation voltage
  • High collector current capability: IC and ICM
  • High collector current gain (hFE ) at high IC
  • Higher efficiency leading to less heat generation
  • Reduced PCB area requirements compared to DPAK.
  • AEC-Q101 qualified


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