ROHM announced the start of online sales for new silicon carbide molded modules, including the TRCDRIVE pack™, HSDIP20 and DOT-247 series. The new modules are designed to promote wider adoption of high-efficiency SiC-based power conversion technologies as global demand for energy-efficient power systems continues to grow.
The products are available for online purchase through distributors such as DigiKey and Farnell.
The TRCDRIVE pack™ is a 2-in-1 SiC molded module designed for traction inverters in electric vehicles with power levels up to 300 kW. It integrates ROHM’s fourth-generation SiC MOSFETs with low on-resistance, enabling approximately 1.5× higher power density compared with conventional SiC molded modules. The module also features a terminal layout that allows the gate driver board to be connected from the top, simplifying assembly and reducing installation time. Example applications include xEV traction inverters.
The HSDIP20 module is available in 4-in-1 and 6-in-1 configurations and targets applications such as xEV onboard chargers, EV charging stations, server power supplies and AC servo systems. The lineup includes six models rated at 750 V and seven models rated at 1200 V. The modules integrate the essential power conversion circuits into a compact package, reducing design complexity and enabling smaller power conversion systems.
The DOT-247 module is a 2-in-1 SiC module designed primarily for industrial applications such as photovoltaic inverters and uninterruptible power supply systems. It retains the versatility of the widely used TO-247 package while delivering higher power density. The module supports both half-bridge and common-source circuit configurations and helps reduce component count and PCB area in power conversion circuits.
Applications for the new SiC modules include electric vehicle systems such as onboard chargers, DC-DC converters and electric compressors, as well as industrial equipment including EV charging stations, V2X systems, PV inverters, power conditioners and AI data center power systems.
