SiC power module for high power applications

The BSM300D12P2E001 is a full SiC power module intended for inverters and converters in solar power conditioners and industrial equipment. The device has a current rating of 300 A making it suitable for high power applications such as large-capacity power supplies for industrial equipment. Moreover, the BSM300D12P2E001 has a 77% lower switching loss compared with conventional IGBT modules which enables high-frequency operation therefore contributes to smaller cooling countermeasures and peripheral components.

In March 2012, ROHM began mass production of the world’s first full SiC power module with an integrated power semiconductor element composed entirely of silicon carbide, and its 120 A and 180 A/1200 V products continue to see increased adoption in the industrial and power sectors. And although further increases in current are expected due to energy-saving effects, in order to take advantage of the high-speed switching capability of SiC products an entirely new package design was needed that can minimize the effects of surge voltage during switching which can become particularly problematic at higher currents.

In response, the BSM300D12P2E001 features an optimized the chip layout and module construction that significantly reduces internal inductance, suppressing surge voltage while enabling support for higher current operation up to 300 A. And going forward ROHM will continue to strengthen its lineups by developing products compatible with larger currents that incorporate SiC devices utilizing high voltage modules and trench structures.
