Infineon Technologies has developed a 1300 V silicon carbide (SiC) power module that is the first to operate at a temperature of 205 C, writes Nick Flaherty.

The HybridPACK Drive module is capable of continuous operation at temperatures up to 205 C. Existing designs typically allow temperatures of up to 175 C. This increase enables automotive OEMs and Tier 1 suppliers to deliver higher peak and continuous output power from existing inverter designs or, in new designs, reduce system complexity and overall cost.

Higher operating temperatures provide engineers with more design flexibility and enable lower system cost. The increased operating temperature enables up to 15% higher output current compared with that of existing designs, directly translating into higher inverter power density.

At the same time, the identical module size, footprint and interfaces allow integration into existing platforms, enabling performance upgrades without costly redesigns or extended development cycles. This drop-in compatibility accelerates time-to-market for next-generation inverter designs while leveraging proven manufacturing and qualification processes.

The extended temperature capability can also significantly reduce cooling system requirements. Tolerating higher junction temperatures allows inverter designs to use smaller or less complex cooling systems, lower system cost, reduce vehicle weight and improve overall efficiency for packs at 800 and 900 V.

The FS01M9R13A7MA2B is the first device with 205 C operating capability in Infineon’s HybridPACK Drive SiC module portfolio, and Infineon plans to roll out the 205 C operating capability across its existing 1200 V SiC modules.
