Mitsubishi Electric announced new J1-Series high-power semiconductor modules featuring compact 6-in-1 packages mainly for use in electric and hybrid vehicles. Power modules for automobiles must deliver higher reliability than industrial-use modules due to the extremely high standards for vehicle safety.
Since then the demand for these modules has grown in parallel with the expanding global market for electric and hybrid vehicles. The new high-power J1-Series modules feature compact packages with small footprints, low power loss and high reliability for use in the inverters of electric and hybrid vehicles.
The 6-in-1 package design shrinks the inverter footprint to about 60% of inverters based on six 2-in-1 J-Series T-PM (CT300DJH120) modules, it provides an extra-compact package for automotive inverters. Low power loss and high reliability for automotive power trains is achieved with the seventh generation CSTBTTM chip technology that enables a reduction of the collector-emitter saturation voltage by about 10% compared to 2-in-1 J-Series T-PM (CT300DJH120). In addition, the direct cooling package with cooling fin improves heat radiation by about 30% compared to 2-in-1 J-Series T-PM (CT300DJH120) mounting power modules on Al fin by way of thermal grease.
Surge voltage suppression through internal inductance reduction makes the new module’s low-inductance package suitable for high-frequency switching applications. Internal inductance is reduced by about 30% compared to 2-in-1 J-Series T-PM (CT300DJH120).
First samples of the new 650V/1000A and 1200V/600A modules will be available from October respectively December 2015. J1-Series power modules are compliant with the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment (RoHS) directive 2011/65/EU.
