Onsemi takes next step in SiC innovation
Onsemi has introduced its latest generation SiC technology platform, EliteSiC M3e MOSFETs. The company also disclosed plans to release multiple additional generations through 2030.
According to Onsemi, the EliteSiC M3e MOSFETs achieve a significant reduction in both conduction and switching losses. Compared to previous generations, the platform can reduce conduction losses by 30 percent and turn-off losses by up to 50 percent.
The EliteSiC M3e MOSFETs are also claimed to offer the industry’s lowest specific on-resistance (RSP) with short circuit capability which is critical for the traction inverter market that dominates SiC volume.
Packaged in Onsemi’s discrete and power modules, the 1200V M3e die delivers substantially more phase current than previous EliteSiC technology, resulting in approximately 20 percent more output power in the same traction inverter housing.
Conversely, a fixed power level can now be designed with 20 percent less SiC content, saving costs while enabling the design of smaller, lighter and more reliable systems.
Onsemi says that with each new generation of SiC, cell structures will be optimised to efficiently push more current through a smaller area, increasing power density. Moreover the company says it can develop multiple generations in parallel and accelerate its roadmap to bring several new EliteSiC products to market at an accelerated pace through 2030.
“We are applying our decades of experience in power semiconductors to push the boundaries of speed and innovation in our engineering and manufacturing capabilities to meet the rising global energy demands,” said Mrinal Das, senior director of technical marketing, Power Solutions Group, Onsemi. “There is a huge technical interdependency between the materials, device and package in SiC. Having full ownership over these key aspects allows us to have control over the design and manufacturing process and bring new generations to market much faster.”
Onsemi provides gate drivers, DC-DC converters, e-Fuses and more to pair with the EliteSiC M3e platform. The EliteSiC M3e MOSFET in the industry-standard TO-247-4L package is now sampling.
