J1-Series high-power semiconductor modules

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 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.

Features of Sample Products
1) Extra-compact package for automotive inverters
-The 6-in-1 package design shrinks inverter footprint to about 60% of six 2-in-1 J-Series T-PM (CT300DJH120) inverters.
2) Low power loss and high reliability for automotive power train
-Seventh-generation CSTBTTM chip technology enables collector-emitter saturation voltage to be reduced by about 10% compared to 2-in-1 J-Series T-PM (CT300DJH120) chips.
-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.
3) Suppresses surge voltage through internal inductance reduction
-Low-inductance package adopted for high-frequency switching applications.
-Internal inductance reduced by about 30% compared to 2-in-1 J-Series T-PM (CT300DJH120).
Environmental Awareness
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.
