Tesla relies on SiC modules from STMicroelectronics

The recent SiC module developed by STMicroelectronics for Tesla and its Model 3 is a good example of this early adoption. The SiC-based inverter, analyzed by System Plus Consulting, Yole’s sister company, is composed of 24 1-in-1 power modules. Each module contains two SiC MOSFETs with an innovative die attach solution and connected directly on the terminals with copper clips and thermally dissipated by copper baseplates. The thermal dissipation of the modules is performed thanks to a specifically designed pin-fin heatsink.

“SiC MOSFET is manufactured with the latest STMicroelectronics technology design,” explains Dr. Elena Barbarini, Head of Department Devices at System Plus Consulting. “This technical choice allows to reduce conduction losses as well as switching losses”. STMicroelectronics is strongly involved in the development of SiC-based modules for the automotive industry. During its recent Capital Markets Day, the ST detailed its activities in this field (Source: Automotive & Discrete Group presentation – May 2018). STMicroelectronics is also committed in the development of innovative packaging solutions. System Plus Consulting proposes today a complete teardown analysis including a detailed estimation of the production cost of the module and its package.
