IXYS Corporation/Littelfuse offers an expansion of its benchmark XPT IGBT product line with new 600 V discrete additions. These new discrete IGBTs are tailored to address market demands for highly rugged, low loss semiconductor devices that offer the ability to be easily configured in parallel. The featured devices demonstrate superior performance and exceptional ruggedness in applications such as power inverters, uninterruptible power supplies, motor drives, switch mode power supplies, power factor correction circuits, battery chargers, welding machines, and lamp ballasts.
Initial release of these new discrete XPT IGBTs will include devices that are available with current ratings from 100 to 210 A. Developed using IXYS/Littelfuse's extreme light PT (XPT) design platform, these new devices feature excellent electrical characteristics, which include low typical Vcesat as low as 1.8 V, low typical current fall times (tfi as low as 42 ns), and low typical turn-off energy per pulse values (Eoff as low as 0.33 mJ). In addition, they demonstrate exceptional ruggedness during switching and under short circuit conditions, establishing a new benchmark in device ruggedness. This is achieved through a 10 us short circuit safe operating area (SCSOA), dynamic avalanche ratings, and a square reverse bias safe operating area (RBSOA) rated up to the device’s blocking voltage. Furthermore, these devices feature an extended forward bias safe operating area (FBSOA), allowing for a “wider operating window” as dictated by the power limitations of the device, resulting in improved ruggedness and reliability.
IXYS/Littelfuse XPT IGBTs are available in two distinctive speed classifications; the B3 and C3 Classes respectively. The B3 and C3 speed classifications offer designers with a more flexible approach to device selection regarding critical requirements such as switching frequency, saturation voltage, and cost. B3-Class devices feature an excellent balance between conduction and switching losses and are optimized for hard switching frequencies from 10 to 30 kHz. C3-Class devices are optimized for minimal switching losses and are recommended for hard switching frequencies from 20 to 60 kHz.
