1. Overview
Leading-edge power technologies for both high-voltage and low-voltage applications combined with a full package range and innovative die bonding technologies exemplify ST’s innovation in power transistors. Our portfolio includes MOSFETs ranging from -500 to 1500V, silicon carbide (SiC) MOSFETs featuring the industry’s highest temperature rating of 200°C, IGBTs with breakdown voltages ranging from 350 to 1300V and a wide range of power bipolar transistors

ST’s broad range of power bipolar transistors will give you the perfect fit for your energy-efficient designs. The range includes Darlington transistors and BJTs with a VCES from 15 to 1700V

Key features of ST’s power bipolar transistors include:


  • Fast switching times and very low saturation voltage resulting in reduced switching and conduction losses
  • Integrated diode versions for reduced component count
  • Well-controlled hFE parameter for increased reliability
  • Best cost-performance ratio
