ROHM’s New 1200V IGBTs Achieve Industry-Leading Low Loss Characteristics with High Short-Circuit Tolerance

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.

The increasing use of higher voltages in automotive systems and industrial equipment has led to a growing demand for power devices capable of handling high voltages in applications such as vehicle electric compressors, HV heaters, and inverters for industrial equipment. At the same time, there is a strong push for high efficiency power devices to improve energy conservation, simplified cooling mechanisms, and smaller form factors for a decarbonized society. Automotive electrical components must also comply with automotive reliability standards, while power devices for inverter and heater circuits are required to provide current interruption capabilities during short circuits, necessitating high short-circuit tolerance (more info).
