STMicroelectronics, a global semiconductor leader serving customers across a wide range of electronics applications, is helping to improve the driving range and fast charging of Volvo's electric vehicles with silicon carbide (SiC) technology.

STMicroelectronics today announced that it is supplying its latest third-generation 750V silicon carbide (SiC) power MOSFET die for power modules based on BorgWarner’s proprietary Viper technology.

The power modules are used in BorgWarner’s traction inverter platform, which supports Volvo Cars’ current and future electric vehicle models.


“This collaboration will help Volvo Cars make electric cars even more appealing by increasing their range and fast-charging capabilities,” said Javier Varela, executive vice president and chief operating officer at Volvo Cars. “It will also build on this to accelerate our journey to full electrification by 2030, while strengthening our vertical integration and control of key components.”

“BorgWarner is pleased to work with ST to supply inverters to support our long-standing customer Volvo Cars’ next-generation BEV platform,” said Stefan Demmerle, BorgWarner Vice President and President and General Manager of PowerDrive Systems. "I think so," he said.

BorgWarner worked closely with ST’s engineering team to maximize the performance of ST’s SiC MOSFET die, matching BorgWarner’s Viper power switches with ST’s die to maximize inverter performance and provide a compact, cost-effective architecture. This collaboration will support the high-capacity performance demanded by the rapidly growing electric vehicle market.

“ST’s collaboration with BorgWarner, a global automotive supplier leading the way in electrification, will enable Volvo Cars to support its customers with electric vehicles that offer greater performance and range,” said Marco Monti, President Automotive and Discrete Group, STMicroelectronics. “By expanding our SiC production capacity and strengthening our SiC supply chain through vertical integration, ST is committed to increasing production to support a smooth transition to electrification and high efficiency for our automotive and industrial customers worldwide.”

ST’s high-volume STPOWER SiC products are manufactured in fabs in Italy and Singapore, with advanced packaging and testing in back-end facilities in Morocco and China. In October 2022, ST announced it was expanding its wide bandgap manufacturing capabilities with a new integrated SiC substrate fabrication facility in Catania, Italy, the home of ST’s power semiconductor expertise and home to its integrated SiC R&D and manufacturing plant.
