DM Silicon Carbide Half-Bridge Power Module

The Wolfspeed DM module family is engineered to provide exceptional current capability in a form factor with a low mass (41 g) and volume. Designers can create high-power density silicon carbide converters for applications with weight and space constraints thanks to DM. With a lightweight AlSiC baseplate and a high-reliability silicon nitride (Si3N4) power substrate to ensure mechanical robustness, the optimized packaging allows for +175°C continuous junction operation.

The DM4 option includes Gen 4 technology, which reduces cosmic FIT rate for operation at higher altitudes. Taking advantage of lower-cost PCBs versus choosing a legacy bus bar solution helps reduce development time and costs.

Common applications for the DM power modules include e-mobility inverters, EV chargers, high-efficiency converters, and renewable energy.
