If your design has to keep power consumption and heat dissipation to a minimum, then our low VCEsat (BISS) devices are the perfect solution. They deliver exceptionally low power consumption and have a high collector current capability (due to an innovative mesh-emitter technology).


This makes them ideal for a host of power sensitive applications, including portable products, telecom and automotive systems, and household appliances, where low heat dissipation is often a critical factor.

Key features

  • Low collector-emitter saturation voltage VCEsat and corresponding resistance RCEsat(down to < 30 mOhm)
  • High collector current capability IC and ICM
  • High collector current gain hFE at high IC
  • High performance in reduced board space
  • Cost effective replacement for larger, medium power and power transistors such as SOT89, SOT223, TO-126 and DPAK

Key applications

  • Medium power peripheral drivers e.g. fan, motor
  • 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
  • Loadswitches
