Wolfspeed Inc. has introduced its 1200-V silicon carbide six-pack power modules, designed for use in high-power inverters, including those found in electric-vehicle (EV) charging and powertrain systems.
The modules use the company’s Gen 4 SiC MOSFET technology and updated packaging to support higher operating temperatures and increased current capability within an industry-standard footprint.
They also incorporate packaging features such as sintered die attach, epoxy encapsulation and copper clip interconnects. These updates are intended to improve power-cycling durability compared with previous versions.
The design provides lower RDS(ON) at high temperatures and reduced switching losses across operating conditions. The soft-body diode also decreases reverse-recovery losses and voltage overshoot compared with earlier models.
The new power modules use a standard package format that can serve as a replacement for IGBT-based designs in existing inverter systems, including EV-related applications. They’re compatible with commonly used power components, such as capacitors, cooling systems, gate drivers and current sensors and do not require power-terminal laser welding or cold-plate mounting.
