Mitsubishi Electric to Release New Higher Current Automotive IPMs of the J-Series

PM800CJG060G is combining a rating of 600V/800A with a low saturation voltage of typically 1.8V at Tj=25°C. For PM500CJG120G these values are 1200V/500A with a typical saturation voltage of 2.0V. Both are supporting at the same footprint area larger currents than existing types of the J-series, starting from 300A at 600V rating respectively from 150A at 1200V. Additionally, both are equipped with built-in power supplies for IGBT drive and logic circuits. First samples will be available from August 2013 onwards. Mass production of the RoHS compliant modules is expected to begin in 2014.

Common features of the IPM J-Series are IGBT driver & protection functions (e.g. short-circuit protection, control-power-supply under-voltage protection, over-temperature protection and fault signaling output) and an isolation by using automotive high-grade photo-couplers. Additionally this J-Series provides analog output functions on a high-accuracy level to monitor the temperature at the chip center and the inverter DC-link voltage (optional). All J-Series IPM can be controlled by a ready-signal input for fail-safe operation. Vibration-resistant connectors are securing high reliable interface stability in the customer designs.

Power modules for automobiles offer higher reliability than industrial-use modules due to 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..
