900A, 6.5kV press-pack IGBT includes anti-parallel diode
The 6.5kV device is asymmetrical blocking and has a fully rated anti-parallel diode 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. The device is housed in an 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, says the company. The T0900DF65A will allow the higher voltage rating to be implemented in much higher power applications, up to several MW, and extends the company’s three level inverter stacks to serve the American 4160V standard without series connection. Applications include medium voltage drives for industrial, marine and renewable energy infrastructure applications, including wind generation, traction applications, main drives and auxiliary power supplies and HVDC.
