This improves efficiency at the system level, enhances power density, reduces electromagnetic interference (EMI) and reduces system size and weight. New generation SiC MOSFETs employ a novel active cell design combined with advanced thin wafer technology enabling best in class figure of merit Rsp (Rdson*area) for 650V breakdown voltage. Devices have low Rdson (12 mOhm) in D2PAK7L and To247 packages. Technology is also optimized around energy loss figure of merits, optimizing performance in automotive and industrial applications. An internal gate resistor (Rg) allows more flexibility to designers eliminating the need to slow down devices artificially with external gate resistors.
