Classified according to transition frequency and noise / gain performance, our wideband transistors offer a host of package, process and specifications options. The range is now up to its 7th generation, delivering operating frequencies from 100 MHz to 20 GHz.

Automotive Bipolar Transistors

The fT-IT C curve represents Transition Frequency (fT T) characteristics as a function of collector current (IT C) for the six generations of RF wideband transistors. A group of transistors having the same collector current (IT C) & similar transition frequencies (fT T) represents a curve. The curve number matches products in the table, detailing their RF characteristics.



  • Very high gain
  • Broad portfolio (1st - 7th generation)
  • Low noise
  • Short leadtimes
  • Low current consumption
  • Smallest packages
  • Easier heatsinking - via emitter lead
  • Volume delivery
  • Wide range of package options including SOT343F, a small, 4-pin, flat-lead plastic SMD package

Target Applications

  • Mobile phone ODM/CEM designs
