Alternative Super Junction Power MOSFETs for power electronics design

Super Junction MOSFETs (SJ-MOSFETs) are high-performance MOSFETs designed for higher power and voltage switching and used in voltage converters.

In contrast to conventional MOSFETs, SJ MOSFETs have a much larger pn junction between source and drain. This leads to an extremely low contact resistance between said electrodes. This is in the switched state (on) at about 0.1 ohms. This low on resistance causes low heat development due to the power loss.

Karl Kruse, a global distributor of electronic components, and CYG Wayon, is one of global core providers of electronic circuit protection solutions, announced a cooperation agreement.

“We are thrilled to partner with CYG Wayon, as a distributor,” said Klaus Kruse, Managing Director of Karl Kruse. “Wayon’s unique offerings in the Over-Voltage Protection & Semiconductor Devices market offer a perfect match for our customer’s needs, specifically in the industry market. We are able to cross major manufacturers, offer better costs and much shorter lead times,” commented Kruse. “Furthermore, Wayon’s commitment to quality and reliability resonates Karl Kruse’s dedication to provide our expansive customer base with top-tier components,” added Kruse.

Wayon WMOS ™ C2 is a new silicon-based cutting-edge technology for high voltage power MOSFET. Using advanced super junction principle, the technology can reduce RDS (on) per area significantly compared to conventional VDMOS. This technology achieves up to 38% better FOM (RDS (on)*Qg) versus the previous WMOSTM C1 technology. This improvement makes switching applications more efficient and more compact. WMOSTM C2 provides wide voltage range MOSFETs and is cost-effective compared to VDMOS.

CYG Wayon 800V WMOS™ M3 is a new silicon-based cutting-edge technology, which features extremely low gate charge for high efficiency when switching, especially for high frequency switching. With enhanced design, the new WMOSTM M3 family has also strong surge performance for LED application.
