Mar 05, 2024BorgWarner gets SiC power from ST as well as Onsemi
Only a few weeks ago Onsemi announced that its silicon carbide power transistors are to be used in BorgWarner Viper electric vehicle traction inverters, and now STMicroelectronics has revealed something similar.
“STMicroelectronics will supply BorgWarner with third-generation 750V silicon carbide power mosfet die for their proprietary Viper-based power module,” according to ST. “This power module is used in BorgWarner’s traction inverter platforms for several current and future Volvo Cars electric vehicles.”
It continued that the two companies collaborated to match ST’s SiC mosfet die with “BorgWarner’s Viper power switch” – Electronics Weekly has asked about the nature of the switch here – watch this space.
Such is the demand foreseen for SiC power components, that companies up and down the supply chain have signed multiple deals to ensure continuity of supply.
“This collaboration [with ST and BorgWarner] will strengthen our increased vertical integration and our control of critical components,” said Volvo COO Javier Varela.
ST’s high-volume SiC products are manufactured in its own Italian and Singapore fabs, with back-end packaging and testing at its facilities in Morocco and China.
In October last year, ST announced it would build a SiC substrate production line in Catania Sicily, where is has power semiconductor research, development and manufacturing.
