Power modules for automobiles must deliver higher reliability than industrial-use modules due to the extremely high standards for vehicle safety. Mitsubishi Electric pioneered the mass production of power modules for hybrid vehicles in 1997, and since then the demand for these modules has grown in parallel with the expanding global market for electric and hybrid vehicles. The new J1-Series power modules feature compact package with small footprint, low power loss and high reliability for use in the inverters of electric and hybrid vehicles. Mass production is expected to begin in 2015.
