SiC Modules – 10kW to 350kW

Semikron Danfoss Silicon Carbide power modules combine industry standard housings, sophisticated packaging technologies, and the latest SiC chips.

Silicon Carbide Power Modules Benefits

Semikron Danfoss´ hybrid SiC and SiC MOSFET power modules combine the benefits of proven industry standard power modules with Semikron Danfoss packaging technologies. Thanks to various packaging optimizations, all the benefits that silicon carbide offers can be fully exploited.

A low module commutation inductance allows for full speed switching of SiC MOSFETs. The higher switching speeds can be converted into higher switching frequencies, resulting in smaller magnetic filter components. At the same time, the switching losses can be reduced, increasing system efficiency. Sophisticated materials and packaging technologies minimize the thermal resistance of the chip to the heatsink, enabling higher power densities.

    SEMITOP E1/E2 SiC MOSFET Platform

    The SEMITOP E1/E2 SiC MOSFET platform delivers the latest chip generations in multiple topologies, including sixpack, half-bridge and H-bridge.

    The SEMITOP E2 half-bridges come in two different pin-outs:

    • Pin-out 1 allows for a multiple-sourcing strategy down to the chip level
    • Pin-out 2 is highly optimized for easy PCB designs and paralleling several power modules.

    The SEMITOP E1/E2 Silicon Carbide features a low specific resistance (specific RDS(on)) temperature coefficient. Combined with one of the lowest thermal resistance values of the module package this leads to unprecedented performance. The RDS(on) temperature coefficient is as low as 0.1mΩ/K.

    Thanks to thorough simulations during the design phase, all modules are designed for highest switching speeds, exhibiting high performance and stable operation at the same time. The high value of the ratio of input capacitance to Miller capacitance (ciss/crss) protects against parasitic turn-on.
