en.Wedoany.com Reported - U.S. semiconductor company Wolfspeed has launched its fifth-generation silicon carbide (SiC) MOSFET platform, targeting next-generation 1200V and 750V automotive and industrial power systems, aiming to reduce specific on-resistance (RSP) and improve high-temperature performance. Compared to existing competitive 1200V SiC solutions, the new technology can reduce RSP by up to 27%, directly lowering conduction losses and helping system designers enhance current capability, improve inverter efficiency, and reduce overall size.
The first two devices released are the 1200V model QEM50120-025D10 and the 750V model QEM50075-025D10. The 1200V device achieves a chip-level RSP of 3.4 mΩ-cm² at 175°C, while the 750V version reaches 2.0 mΩ-cm² at the same temperature. Both voltage levels specify a strict RDS(ON) distribution of ±18%, helping to reduce design margin requirements in high-performance systems.
The new MOSFETs are suitable for electric vehicle traction inverters, on-board chargers, fast charging infrastructure, industrial power supplies, and solid-state protection systems. Lower conduction and switching losses can improve vehicle range, reduce cooling system size, and increase power density; in electric vehicle platforms, they support more compact inverter designs and may also reduce battery size requirements for a given range.
Gen 5 devices retain the soft body diode structure introduced in the previous generation while extending the maximum continuous junction temperature to 200°C, with limited-life operation up to 215°C. This combination improves reverse recovery behavior and overall switching performance while supporting long-term system reliability in harsh environments. Production is based on Wolfspeed's 200 mm SiC manufacturing platform at its Mohawk Valley facility in New York. The new generation of products has completed design and qualification, ready for mass production using existing infrastructure that can be quickly ramped up, allowing customers to transition from design verification to production without requiring new manufacturing tools.
Samples of the first Gen 5 devices, QEM50120-025D10 and QEM50075-025D10, are now available to select customers, with more 750V and 1200V products expected to be launched throughout 2026 and into early 2027.
