Contributes to higher efficiency in automotive electric compressors and inverters for industrial equipment

ROHM has developed automotive-grade AEC-Q101 qualified 4th Generation 1200V IGBTs that combine class-leading* low loss characteristics with high short-circuit resistance. This makes the devices ideal for vehicle electric compressors and HV heaters as well as industrial inverters. The current lineup includes four models - RGA80TRX2HR / RGA80TRX2EHR / RGA80TSX2HR / RGA80TSX2EHR - in two discrete package types (TO-247-4L and TO-247N), along with 11 bare chip variants - SG84xxWN - with plans to further expand the lineup in the future.

ROHM redesigned the device structure and adopted an appropriate package to develop new 4th Generation IGBTs suitable for high voltage by delivering industry-low loss characteristics with superior short-circuit tolerance. These devices achieve an industry-leading* short-circuit withstand time of 10µs (Tj=25°C) together with low switching and conduction losses while maintaining a high withstand voltage of 1200V and meeting automotive standards by reviewing the device structure, including the peripheral design. At the same time, the new TO-247-4L package products, which feature 4 terminals, can accommodate an effective voltage of 1100V in a ‘Pollution Degree 2 environment’ by ensuring adequate creepage distance between pins. This enables support for higher voltage applications than conventional products.
