What happened
onsemi launched EliteSiC M4, its fourth-generation silicon carbide platform based on a trench architecture for next-generation power systems.S1 The company says the platform delivers up to 30% higher power density and 35% lower losses than the preceding generation, targeting AI data centers, electric vehicles and energy infrastructure.S1
The platform is intended to support more compact power conversion within existing space, thermal and efficiency constraints, with lower cooling requirements.S1 onsemi says its silicon carbide experience includes more than 16 billion miles of real-world operation in automotive and industrial applications.S1
EliteSiC M4 reduces specific on-resistance, or RSP, by 20% to 50%, which onsemi links to lower conduction losses and faster switching.S1 Its switching figures of merit improve by 67% in hard-switching applications and by 50% in soft-switching environments.S1
Available formats include top-side-cooled surface-mount packages and high-power modules.S1 The technology is qualified for operating temperatures of 185°C and above in automotive, industrial and other high-reliability applications.S1
The first EliteSiC M4 product, a 750 V bare die for automotive traction inverters, is available immediately.S1 Additional devices with voltage ratings up to 1200 V are expected to begin appearing in 2027.S1

Background timeline
XAIPART take
Technical impact
XAIPART analysis Engineers evaluating compact converters should benchmark EliteSiC M4 at their actual switching frequency, gate drive and thermal conditions rather than rely on headline comparisons. Package selection, die-level paralleling and cooling design will determine how much of the advertised electrical improvement reaches the finished converter.
Market impact
XAIPART analysis A 750 V bare die gives automotive inverter teams an early sourcing path, but a bare die carries different assembly and traceability requirements from a packaged component. The source discloses neither lead times nor pricing, so buyers should treat near-term capacity and cost as unresolved rather than assume immediate availability across all voltage classes.
Action
XAIPART analysis Request samples, electrical characterization data and assembly requirements for the 750 V die, and ask onsemi to clarify when packaged variants will cover the full voltage range. Procurement should also request a delivery plan and production-volume forecast before committing an automotive program to this roadmap.
XAIPART Forecast
XAIPART analysis XAIPART expects onsemi to introduce at least one EliteSiC M4 device rated above 750 V and no higher than 1200 V within 9 months; if no such device is released within that window, this forecast is wrong. This threshold tracks device-class breadth, an engineering-relevant measure of portfolio availability rather than market demand.
Facts are as reported by the cited source. The design-in, sourcing and forward-looking statements above are XAIPART's analysis, not the source's claims. Pricing, lead times, production volumes and a complete rollout schedule were not disclosed, and the performance figures remain single-source vendor claims as presented by the publication.
Corrections: none at publication. This brief will be updated with a timestamp if the source corrects its report.
