600V fast-switching rugged IGBT from IR for automotive power supply applications

International Rectifier (IR) has introduced an innovative 600V automotive grade IGBT platform, COOLiRIGBT for use in fast switching applications for electric (EV) and hybrid electric vehicles (HEV) including on-board DC-DC converters, motor drives, and battery chargers.

The new Gen. 1 COOLiRIGBT devices are capable of operating at the same fast switching 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 5µs, low Vce(on) and positive Vce(on) temperature coefficient. Additional features common to the family include square reverse bias safe operating area (SRBSOA) and maximum junction temperature of 175°C. COOLiRIGBT also provides designers with the flexibility of selecting a diode with optimized performance for the application.

"With an extended temperature range of 175°C and much simpler and more rugged device structure, IR's 200kHz capable COOLiRIGBTs offer a superior and lower cost solution for fast switching applications such as HEV DC-DC converters or chargers and power supplies used in Plug-in-HEVs and EVs compared to super junction MOSFETs," said Benjamin Jackson, senior power switch product manager, IR's automotive products business unit.

The 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. In addition to offering a maximum junction temperature and hard switching up to 200kHz, the two devices deliver better performance of higher currents due to lower conduction losses and enhanced efficiency when used in resonant Zero Current Switching (ZCS) topologies.

The new devices are lead-free and RoHS compliant.
