The device is housed in a fully hermetic press-pack package with 66mm diameter copper electrodes and an overall package diameter of 100mm. The internal construction is based on the same high reliability construction as IXYS UK’s well established 4.5kV product lines, but with a larger individual die size to optimise die active area and the overall efficiency of rating within the package. As with all IXYS UK’s press-pack IGBT products, the new device is inherently robust with phenomenal thermal cycling endurance, double sided cooling and ruggedness in failures without package rupture.
“For medium voltage applications these new higher voltage devices give the option to reduce the number of series devices in the phase leg switches; thereby giving better economy for ancillary and mechanical components. IXYS UK has launched this new product in advance of much larger devices to give our potential customers an opportunity to try the new technology with a device rated at 900A planned for introduction in May 2014 and larger devices towards the end of the year,” commented Frank Wakeman, IXYS UK’s Marketing and Technical Support Manager.
Typical applications include medium voltage drives for industrial, marine and renewable energy infrastructure applications, including wind generation; traction applications including light rail and auxiliary power supplies; as well as HVDC and infrastructure applications such as grid interconnects.
