With current ratings ranging from 16A to 200A, these new devices are designed to achieve an optimal balance between the turn-off energy loss and on-state voltage, especially in hard-switching applications. Able to support switching frequencies up to 60 kHz, they allow designers to use smaller and lighter components in their systems. Devices co-packed with anti-parallel fast diodes are also available.

Built with the proprietary Extreme-light Punch-Through (XPT™) technology, and the 3rd generation (GenX3™) IGBT process, these devices exhibit such qualities as reduced thermal resistance, low tail current, low energy loss, and high-speed switching capability. They are avalanche rated and able to withstand short-circuit conditions. They also have square Reverse Bias Safe Operating Areas (RBSOAs) up to the breakdown voltage of 650V. All of these attributes make them rugged and particularly useful for snubberless hard-switching designs.

Other advantages include low gate charge and a positive temperature coefficient of the on-state voltage, translating into lower gate drive requirements and multiple-device paralleling capability, respectively. Moreover the optional co-packed diode ‘Sonic-FRD™’ is optimized to help reduce turn-off losses and suppress ringing oscillations that can cause Electromagnetic Interference (EMI) in the system. These diodes can also be operated in parallel thanks to the temperature stability of the forward voltage.

A wide array of power conversion applications can benefit from deploying these new IGBTs. Among these are power inverters, uninterruptible power supplies, switch-mode power supplies, power factor correction circuits, battery chargers, welding machines, lamp ballasts, and E-Bikes.

The new 650V XPT™ IGBTs are available in the following international standard size packages: TO-220 (regular and over-molded), TO-247, TO-263, TO-268HV, and SOT-227B. The TO-268HV is a proprietary high-voltage package with an increased creepage distance between leads, compared to the standard package. Some example part numbers include IXYP15N65C3D1M, IXYP10N65C3, IXYH40N65C3H1, and IXYH100N65C3, with collector current ratings of 16A, 30A, 80A, and 200A, respectively.
