Efciency Through Technology Extreme-Light Punch-Through IGBTs for High-Speed Hard-Switching Applications October 2012 OVERVIEW IXYS Corporation expands its 1200V XPT™ IGBT product line. With current ratings of up to 220A, these new devices are designed to minimize switching losses in high-voltage, hard-switching applications. The high-speed switching capabilities (up to 50 kHz) of these IGBTs allow designers to use smaller and lighter components in their systems. For those IXYS customers who need to lower turn-o losses and/or remove snubbers/clamps from their designs, IGBTs with co-packed ultra-fast recovery diodes in Sonic-FRD™ or HiPerFRED™ Technology are available. Manufactured through the state-of-the-art GenX3™ IGBT process and an extreme-light PunchThrough (XPT™) design platform, these devices feature high-current handling capabilities, high-speed switching abilities, low total energy losses, and low current fall times. They have a positive collector-to-emitter voltage temperature coecient, making it possible for designers to use multiple devices in parallel to meet high current requirements. Their low gate charges also help reduce gate drive requirements and switching losses. In addition to being avalanche rated, these devices have square Reverse Bias Safe Operating Areas (RBSOA) up to the breakdown voltage of 1200V – a necessary ruggedness in snubberless hard-switching applications. The new 1200V XPT™ devices with co-packed anti-parallel Sonic-FRD™ or HiPerFRED™ diodes are optimized to reduce turn-o losses and suppress ringing oscillations, thereby producing smooth switching waveforms and signicantly lowering electromagnetic interference (EMI) in the process. Furthermore, due to the soft recovery characteristics of the diodes, the IGBTs can be switched on at very high rates of change in current (di/dt), even in low current and temperature conditions. There are various high-voltage and high-speed applications that the new IGBTs are well-suited for. Among these are power inverters, uninterruptible power supplies, motor drives, switch-mode power supplies, power factor correction circuits, battery chargers, welding machines, and lamp ballasts. TO-220 These 1200V XPT™ IGBTs are available in the following industry standard packages: TO-220, TO-247, ISO TO-247™, TO-264, SOT-227B, SOT-227B, PLUS247, PLUS264™ and ISOPLUS247™.
