Infineon Technologies, a producer of semiconductors for power systems and IoT applications, will supply Rivian’s R2 platform with power modules for traction inverters. The R2 platform will use silicon carbide (SiC) and silicon (Si) modules from Infineon’s HybridPACK Drive G2 family. Infineon expects to start delivering the components in 2026.

HybridPACK Drive is Infineon’s power module family for electric vehicles. The company says it has sold over 10.5 million units since 2017.

Infineon will also supply other products for Rivian’s new EV platform, including AURIX TC3x microcontrollers and OPTIREG power management ICs.

Infineon is building a new 200-millimeter SiC power “fab” (the semiconductor industry’s term for a fabrication plant) in Kulim, Malaysia. This will share production technologies and processes with the company’s existing fab in Villach, Austria, enabling fast ramping and efficient operations in SiC and gallium nitride (GaN) manufacturing.

“We are committed to enhancing the performance and range of electric vehicles jointly with innovative automotive companies like Rivian,” said Stefan Obersriebnig, head of the product line for high-voltage modules in Infineon’s Automotive Division. “Our dedication for innovation and zero-defect quality has made us the preferred partner of the automotive industry.”

I love the packaging on Maximus — the drive unit for R2. It has a side mounted inverter that utilizes flat area at the end of the motor to minimize the length of bus bars, keeping them light and efficient. The large planar shape also allows all processing and power electronics to… pic.twitter.com/czFV6FYhBN
