onsemi, a leader in intelligent power and sensing technologies, announced the release of the latest generation of 1200 V EliteSiC silicon carbide (SiC) M3S devices, which enable power electronics designers to achieve best-in-class efficiency and lower system cost. The new portfolio includes EliteSiC MOSFETs and modules that facilitate higher switching speeds to support the growing number of 800 V electric vehicle (EV) on-board charger (OBC) and energy infrastructure applications, such as EV charging, solar and energy storage systems.
Also, part of the portfolio, are new EliteSiC M3S devices in half-bridge power integrated modules (PIMs) with industry leading lowest Rds(on) in a standard F2 package. Targeting industrial applications, the modules are ideally suited for DC-AC, AC-DC and DC-DC high power conversion stages. They provide higher levels of integration with optimized direct bonded copper designs to enable balanced current sharing and thermal distribution between parallel switches. The PIMs are designed to deliver high power density in energy infrastructure, EV DC fast charging and uninterruptible power supplies (UPS).
“onsemi’s latest generation of automotive and industrial EliteSiC M3S products will allow designers to reduce their application footprint and system cooling requirements,” said Asif Jakwani, senior vice president and general manager of the Advanced Power Division, onsemi. “This helps designers to develop high power converters with higher levels of efficiency and increased power densities.”
The automotive-qualified 1200 V EliteSiC MOSFETs are tailored for high-power OBCs up to 22 kW and high voltage to low voltage DC-DC converters. M3S technology has been developed specifically for high-speed switching applications and has the best-in-class figure of merits for switching losses.

onsemi, a leader in intelligent power and sensing technologies, and premium electric mobility brand ZEEKR announced a long-term supply agreement (LTSA) between the two companies. onsemi will provide its EliteSiC silicon carbide (SiC) power devices to increase the powertrain efficiency of ZEEKR’s smart electric vehicles (EVs), resulting in improved performance, faster charging speeds and extended driving range.
To support its expanding portfolio of high-performance EVs, ZEEKR will adopt onsemi EliteSiC MOSFET, 1200V, M3E with enhanced electrical and mechanical performance and reliability. These power devices deliver improved power and thermal efficiency, which reduces the size and weight of the traction inverter and enhances the range of the automaker’s EVs.
“With cutting-edge technologies such as advanced SiC, ZEEKR will be able to offer electric vehicles with improved performance and even lower carbon emissions,” said Andy An, CEO of ZEEKR Intelligent Technology. “As a brand committed to sustainability, ZEEKR will continue to explore different ways to accelerate the transition towards new energy vehicles.”
The new LTSA will enable both companies to build a stronger supply chain relationship to support ZEEKR’s growth over the next decade.
“A reliable supply chain is critical to business success and, after significant investments in our SiC end-to-end supply chain, onsemi can offer this strategic value to customers,” said Hassane El-Khoury, president and CEO, onsemi. “This agreement will help our continued ramp of SiC operations, enabling us to offer industry-leading power devices that help our customers deploy the most efficient and highest performing EVs on the market.”
ZEEKR is a premium electric mobility brand built to address the global demand for premium EVs. Utilizing Geely’s advanced Sustainable Experience Architecture (SEA), ZEEKR develops in-house battery technologies, battery management systems, electric motor technologies and electric vehicle supply chain support.

onsemi announced a breakthrough in simulation tools for onsemi’s EliteSiC Silicon Carbide (SiC) product family and its applications. The company launched the online Elite Power Simulator and Self-Service PLECS Model Generator, which provide meaningful insights for complex power electronic applications through system-level simulations at an early stage of the development cycle. The tools save power electronic engineers time by providing state-of-the-art accurate simulation data enabling EliteSiC product selection tailored to customer applications, instead of costly and time-consuming hardware fabrication and testing.
Users have ultimate power and flexibility to create high-fidelity system-level PLECS models when the Elite Power Simulator is deployed in conjunction with the Self-Service PLECS Model Generator. Whether uploaded to onsemi’s Elite Power Simulator or downloaded for direct use, the self-service PLECS models deliver the optimization and accuracy required for demanding power electronic simulations. The models are generated based on typical or worst-case conditions to let the customer design within the technology boundaries. The capability to define application-specific parasitics ensures that the generated PLECS models provide highly accurate results for the customer’s system-level simulations.
“Our PLECS simulator has proven very popular with power designers due to speed and ease of use,” said Jost Allmelling, managing director and co-founder, Plexim. “It is particularly exciting to see the truly novel aspects here, including the ability to simulate soft switching accurately, the customized models via the onsemi Self-Service PLECS Model Generator and the ready-made models for corner cases.”
To date, system-level simulators and their associated PLECS models have only been valid for hard switching topologies, with simulation results for soft switching applications such as LLC (inductor-inductor-capacitor) or CLLC (capacitor-inductor-inductor-capacitor) being highly inaccurate. onsemi’s industry-first PLECS models break this trend and solve this problem for customers.
“This is a significant step for the industry, increasing its ability to get both hard and soft switching designs to market quickly,” said Asif Jakwani, senior vice president and general manager of the Advanced Power Division, which is part of the Power Solutions Group at onsemi. “Our tools enable our customers to understand how our devices perform in their application environment and fully optimize the performance within the boundaries of the technology.”
