Electronica: OnSemi reveals electric vehicle silicon carbide deal

“Onsemi provides assurance of supply for its SiC solutions and the necessary scale to support production,” said Onsemi general manager Simon Keeton.

The car, said the chip company, consumes under 10kWh per 100km, has a 100kWh battery and a coefficient of 0.17. It claims that 95% of the energy stored in the traction battery reaches the wheels.

It “completed a 1,202km trip from Stuttgart, Germany to Silverstone, England, holding the record for longest distance travelled on a single charge”, according to Onsemi, which has the whole SiC supply chain in-house: boule growth, substrates, epitaxy, device fabrication, modules and discrete package.

At the same time, car maker Stellantis (Fiat Chrysler Peugeot Citroen Vauxhall ….) has signed a non-binding memorandum-of-understanding with Infineon to use Infineon silicon carbide bare die semiconductors in its vehicles.

If the deal is completed, Infineon would reserve manufacturing capacity and supply CoolSiC Gen2p 750V and 1.2kV die to Stellantis’ tier 1 suppliers in the second half of the decade – with a potential value of “significantly more than €1bn”, according to Infineon.

“Compared to traditional power technologies, silicon carbide increases the range, efficiency and performance of electric vehicles,” claimed Infineon president of automotive Peter Schiefer (pictured). “We believe in electromobility and are excited to develop partnerships with automotive companies like Stellantis.”
