The power module device market will post a 10.2% compound annual growth rate (CAGR) over the next five years. This will impact the power module packaging market, which will see a 9.5% CAGR and reach a value of almost $1.8B.

Power modules have come a long way since the early stages of car electrification, and now play a key role in power modulation through all EV/HEVs, from inverters to bi-directional converters. Packaging these modules has become critical due to several technical aspects: moulding, high-temperature die attach, TIM, and connections.

Power modules must combine good thermal and electrical efficiency, while maintaining a low mass and volume. Also, to remain competitive in an open market, power module makers must deliver high reliability while remaining cost-efficient.

With its new J1-series, Mitsubishi proposes a power module family with voltages in the range of 650V – 1200V, and with a new direct cooling system for automotive applications. Mitsubishi’s modules are extra compact, with direct-cooling substrate 6-in-1 package and pin fin. The modules also integrate the latest Mitsubishi IGBT with Gen7 CSTBT technology and the latest RFC diodes.

The publisher presents a technology and cost analysis of two J1-series power modules with 650V and 600A/1000A, respectively: the CT600CJ1A060 and the CT1000CJ1B060. This report also provides insights into these modules’ structure, technical choices, design, processes, supply chain position, and cost.

Also included in this report is an analysis of the packaging, IGBT, and diode die, along with a cost analysis for all devices. Moreover, we supply a full comparison between the latest generations of Mitsubishi IGBT and diode. Lastly, we compare this module with the technical choices found in Infineon’s HybridPACK drive and Tesla’s SiC Power module molded with ST SiC MOSFET.
