STMicroelectronics is introducing its third generation of STPOWER silicon-carbide (SiC) MOSFETs, targeting electric-vehicle (EV) powertrains and other applications where power density, energy efficiency, and reliability are important target criteria.

ST has incorporated new and advanced design know-how to open up even more of SiC’s energy-saving potential.

With the acceleration of the EV market many car makers and automotive suppliers are now embracing 800V drive systems to achieve much faster charging and help reduce EV weight, producing vehicles with longer driving ranges.

ST’s SiC devices have been optimised for high-end automotive applications including EV traction inverters, on-board chargers, and DC/DC converters, as well as e-climate compressors. This latest generation also suits industrial applications by boosting the efficiency of motor drives, renewable-energy converters and storage systems, as well as telecom and data-centre power supplies.

“We continue to drive this exciting technology forward with innovations at both the device and package levels. As a fully integrated SiC products manufacturer, we are able to deliver continued improved performance to our customers,” said Edoardo Merli, Power Transistor Macro-Division General Manager and Group Vice President of STMicroelectronics’ Automotive and Discrete Group. “We are investing relentlessly to support our automotive and industrial programs expected to generate $1 billion in SiC revenue in 2024.”

Devices with nominal voltage ratings from 650V and 750V up to 1200V will be available, giving more choices for designers to address applications.

ST will be supplying the third-generation devices in various forms, including bare dice, discrete power packages such as STPAK, H2PAK-7L, HiP247-4L, and HU3PAK and power modules of the ACEPACK family.

These packages offer a number of design features such as specially placed cooling tabs that simplify connection to base-plates and heat spreaders in EV applications.

ST has completed qualification of the third-generation SiC technology platform and expects to move most of the derivative products to commercial maturity by the end of 2021.
