ON Semiconductor Expands Its Line Of 650V SiC MOSFETsMarch 15, 2021 by Gary Elinoff
The four new devices feature RDS(ON)s as low as 12mΩ, the best on the market for D2PAK7L and TO247 packaged devices.
These new Silicon Carbide MOSFETs from ON Semiconductor are seen as replacements for outmoded silicon devices in a wide range of switching applications. They will find wide applicability in tough arenas where neither efficiency, power density nor reliability can be compromised.

The Rsp Figure of Merit
On Semiconductor’s new generation of SiC MOSFETs employ a novel active cell design along with advanced thin wafer technology. This accounts the devices’ extremely low figure for the product of RDSON x AREA. This product is defined as the Rsp figure of merit. This same technology also enables lower energy losses
An internal gate resistor (Rg) eliminates the need to slow down devices artificially with external gate resistors. The four new units also deliver greater surge protection and avalanche capability. These factors, along with and short circuit robustness, add up to higher reliability and longer device lifetimes.
Commenting on the new releases, Asif Jakwani, senior vice president of the Advanced Power Division at ON Semiconductor said: “In modern power applications such as on-board chargers (OBC) for EV and other applications including renewable energy, enterprise computing and telecom, efficiency, reliability and power density are constant challenges for designers. These new SiC MOSFETs significantly improve performance over the equivalent silicon switching technologies, allowing engineers to meet these challenging design goals. The enhanced performance delivers lower losses that enhance efficiency and reduce thermal management needs as well as reducing EMI. The end result of using these new SiC MOSFETs is a smaller, lighter, more efficient and more reliable power solution.”
