eMPack® Module Technology for Next Gen EV

Both companies will continue to contribute to automotive technology innovations by providing optimal power solutions.

ROHM’s latest 4th generation of SiC MOSFETs has been fully qualified in SEMIKRON’s eMPack® modules for automotive use.

SEMIKRON announced it had secured a billion-Euro contract to supply its innovative eMPack® module to a major German car maker, beginning in 2025. The company developed a fully sintered assembly and connection technology ‘Direct Pressed Die’ (DPD).

This enables extremely compact, scalable and reliable traction inverters. The eMPack®   module technology has been specially designed for SiC-based converters of medium and high power in order to fully exploit the properties of the new semiconductor material.

In addition, SEMIKRON provides evaluation boards for eMPack® that incorporate ROHM’s gate driver ICs, helping customers shorten the time required for evaluation and adoption. In the future, SEMIKRON also plans to use ROHM’s IGBTs in modules for industrial applications.

“Thanks to ROHM’s SiC technology, SEMIKRON’s innovative eMPack®- family of power modules is ready to make a significant contribution to reducing emissions through e-mobility,” says Karl-Heinz Gaubatz, CEO and CTO at SEMIKRON. “ROHM’s SiC technology provides more efficiency, performance and reliability in automotive and also industrial applications.”

ROHM produces SiC components in-house in a vertically integrated manufacturing system and thus delivers high-quality, energy-saving products while achieving a constant market supply. ROHM’s production subsidiary SiCrystal, located in Nuremberg, Germany, plans to strongly grow its silicon carbide wafer capacities and human resources – to produce several 100,000 substrates a year.

Both companies will continue to contribute to automotive technology innovations by providing optimal power solutions that meet market needs through the fusion of ROHM’s device/control technologies and SEMIKRON’s module technologies that can optimally combine them.
