STMicroelectronics is to supply BorgWarner, a developer of innovative and sustainable mobility solutions, with its latest third generation 750V silicon carbide (SiC) power MOSFETs dice for their proprietary Viper-based power module.

This power module is used in BorgWarner’s traction inverter platforms for several current and future Volvo Cars electric vehicles.

“BorgWarner is pleased to partner with ST to supply our longstanding customer Volvo Cars with inverters for their next generation of BEV platforms,” said Stefan Demmerle, Vice President of BorgWarner and President and General Manager, PowerDrive Systems.

To leverage the improved performance of ST’s SiC MOSFET dice, BorgWarner collaborated closely with ST’s technical team to match their die with BorgWarner’s Viper power switch, so as to maximise inverter performance and deliver a compact and cost-effective architecture.

The collaboration between the companies provides the high-volume capability that is required by the quickly growing EV market.

“Our collaboration with BorgWarner will enable Volvo Cars to offer their customers superior vehicle performance and range,” explained Marco Monti, President, Automotive and Discrete Group, STMicroelectronics. “We are committed to expanding SiC capacity and to reinforcing our SiC supply, including through vertical integration, as we ramp up volumes to support our global automotive and industrial customers in their shift to electrification and higher efficiency.”

ST’s high-volume STPOWER SiC products are manufactured in its fabs in Italy, and Singapore, with advanced packaging and testing at its back-end facilities in Morocco and China.

In October 2022, ST announced it would expand its wide bandgap manufacturing capacity with a new integrated SiC substrate manufacturing facility in Catania, home to the company’s power semiconductor expertise and the site of integrated research, development, and manufacturing of SiC.
