High-frequency IGBT

  • 27-Aug-2012 10:10 EDT


The rugged 600-V automotive-grade insulated-gate bipolar transistor (IGBT) platform COOLiRIGBT from International Rectifier (IR) is suitable for use in a wide range of fast switching applications for electric and hybrid-electric vehicles. Capable of operating at the same speeds as MOSFETs while offering higher efficiency at high current levels, the first-generation COOLiRIGBT devices cover a broad current range and offer a minimum short circuit rating of 5 μs, low Vce(on), and positive Vce(on) temperature coefficient. Additional features common to the family include square reverse bias safe operating area and maximum junction temperature of 175°C (347°F). According to the company, COOLiRIGBT also provides designers with the flexibility of selecting a diode with optimized performance for the application. IR’s AUIRGC655A1N0 is optimized for main electric and hybrid vehicle inverters and large motor drives while the AUIRGC65A20N0 and AUIRGC65G20N0 are targeted for power supply and high-switching-frequency applications.
