May 2014 – IXYS introduces 900A 6.5kV press-pack IGBT

Published on: 29/05/2014

IXYS UK Westcode (now part of Littelfuse) announced today the launch of a new higher current device in its recently introduced 6.5kV press-pack IGBT product family. The new 6.5kV device is asymmetrical blocking with a fully rated anti-parallel diode included within the package. DC collector current rating is 900A with a repetitive peak current rating of over 1800A. Permanent DC forward voltage rating for 100 FIT failure rate is 3.6kV.

New Press-pack IGBT

The device is housed in a fully hermetic press-pack package with 110mm diameter copper electrodes and an overall package diameter of 144mm. Compressed package thickness is 30mm ensuring a greater than 30mm creep path over the convolutions of the ceramic package. The internal construction is based on the same high reliability format as our well established 4.5kV product lines, but with a larger individual die size to optimise die active area and the overall efficiency of rating with-in the package. As with all IXYS UK’s press-pack IGBT products, the new device is inherently robust with phenomenal thermal cycling endurance and the advantage ofpredictable failure to short circuit, without package rupture.

This new 900A addition to the 6.5kV product range will allow the advantages of the higher voltage rating to be implemented in much higher power applications up to several megawatts. For medium voltage applications the higher voltage per device gives the option to reduce the number of series devices in the phase leg switches, giving better economy for ancillary and mechanical components. Also it will allow the extension of our 3 level inverter stacks to serve the popular American 4160V standard without series connection.

Part number for the new device is T0900DF65A.

Typical applications include: medium voltage drives for industrial, marine & renewable energy infrastructure applications, including wind generation; Traction applications including main drives and auxiliary power supplies; as well as HVDC and infrastructure applications such as grid interconnects.
