IXYS Corp. has expanded its GenX3 IGBT portfolio to 1,200V.

These new IGBTs are manufactured using IXYS' GenX3 IGBT process and use IXYS' advanced technology to provide lower saturation voltages, lower switching losses and higher surge current capabilities.

The new extension of GenX3 IGBTs is aimed at the high voltage power conversion market.

To accommodate optimum part selection, designers have a choice in selecting among three sub-classes denoted A3, B3 and C3.

These classifications offer system design flexibility and allow designers to address the trade-off between critical requirements such as switching frequency, efficiency and cost. Co-packed variants of these new devices are available with IXYS' HiPerFRED (suffix 'D1') and SONIC-FRD (suffix 'H1'), ultra-fast recovery diodes providing fast recovery and soft switching characteristics. Additional product attributes include avalanche capabilities and a square reverse bias safe operating area, allowing the device to safely switch in a snubberless hard switching application.

A variety of high-voltage applications stand to benefit from the power handling and efficiency advantages of the new family of IGBTs. Possible applications include solar inverters, automatic voltage regulators, industrial battery chargers, wind turbine inverters, capacitor discharge circuits, electronic circuit breakers, resonant power conversion circuits, induction heating for industrial processing, uninterruptible power supplies, motor drives, switch-mode power supplies, power factor correction circuits and welding machines.

IXYS' 1,200V GenX3 IGBTs are offered in various standard and ISOPLUS packages with collector current ratings Tc=110C from 20A to 120A. Standard packages include the TO-263, TO-247, PLUS247, TO-220, TO-264 and TO-268. Initial device offerings include part numbers IXGA20N120A3, IXGK120N120A3, IXGH30N120B3D1, IXGT30N120B3D1, IXGH24N120C3H1 and IXGR24N120C3D1.
