Rohm began mass production of all-SiC power modules in March 2012 - the 120A and 180A 1,200V products continue are selling into industrial and power sectors. "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 minimise the effects of surge voltage during switching which can become particularly problematic at higher currents," said the firm. In response, it created the BSM300D12P2E001 with improved module construction and a chip layout that reduces internal inductance, suppresses voltage surges, and allows operation at 300A. Inside are two SiC Schottky diodes, two SiC dmosfets, and a thermistor. Maximum junction temperature is 175°C.
