ROHM SiC power devices

Power up with ROHM’s next generation of compact, energy saving SiC power devices

The demand for power continues to grow on a global scale every year while fossil fuel reserves continue to be depleted, further contributing to global warming. Our planet needs power solutions that can make more effective use of our limited resources and provide greater sustainability. To help save energy and reduce our carbon footprint, ROHM offers a broad portfolio of next-generation Silicon Carbide (SiC) Power Devices. Applications for SiC include the power, automotive, railway, and consumer sectors.

SiC is a compound semiconductor comprised of Silicon (Si) and Carbon (C). Compared to conventional Silicon Power Devices, SiC Power Devices deliver higher voltage breakdown, lower ON resistance, faster switching, and higher temperature operation. This translates to lower switching losses, reduced power loss, and smaller module size, allowing designers to make more robust products using fewer components.

ROHM SiC MOSFETs switch without producing any tail current. This enables higher speed switching which reduces switching loss. In addition, low ON resistance and small die size result in lower capacitance and gate charge. SiC exhibits minimal ON resistance increase at higher temperatures compared to standard silicon devices, where the ON resistance can more than double. Applications range from solar inverters, DC/DC converters, and switch mode power supplies to induction heating and motor drives.

SiC Schottky barrier diodes (SBD)

ROHM SiC Schottky Barrier Diodes are majority carrier devices featuring ultra-fast reverse recovery. As a result, switching loss is reduced, enabling high-speed switching operation. In addition, unlike silicon-based fast recovery diodes where the reverse recovery time (trr) increases with temperature, SiC devices maintain constant characteristics that improve performance. SiC SBDs are ideal for applications such as inverters and chargers for EV and solar power conditioners.
