650V IGBTs Optimized for Motor Drive Applications

Alpha and Omega Semiconductor Limited (AOS) today announced the expansion of its IGBT product portfolio with the release of the 650V M-Series. The new M-series is co-packaged with a soft and fast freewheeling diode available in a variety of package types. This platform has been optimized for superior performance with higher robustness in addition to fast and soft turn-off switching in motor drives such as refrigerators, washing machines, fans, air conditioners, treadmills, and sewing machines applications.

All devices for the M-Series are built upon the latest patent pending AlphaIGBTâ„¢ technology platform, and feature very low VCE(SAT) and soft turn-off for higher efficiency and reduced power dissipation. The 650V minimum BVCES rating and rugged breakdown voltage characteristics provide higher reliability during extreme voltage transients. Furthermore, low turn-on di/dt and high turn-on dv/dt switching performance effectively reduces EMI.

“IGBT inverter-driven motor control applications are rapidly expanding in the home appliances area due to their extraordinary energy saving benefits. Selecting the right device is vital to attain an ideal balance of efficiency, robustness and reliability.” said Dr. Brian Suh, Vice President of IGBT product line at AOS. “The 650V M-Series offers system designers the ideal blend of higher efficiency, higher short-circuit endurance time, and EMI performance.”

650V M-Series technical highlights include: 650V IGBTs with soft and fast freewheeling diode; Excellent turn-on performance by low di/dt and high dv/dt; Fast and soft turn-off switching performance; Short circuit rating (tsc) of > 5μs at 400VCC, 15VGE and 150 degrees C; TJ(max) = 175 degrees C. The 650V M-Series IGBTs are immediately available in production quantities with a lead-time of 12-14 weeks.
