Toshiba high performance and small size SiC MOSFET for industrial equipment

Toshiba recently launched the MG800FXF1ZMS3 and MG800FZF1JMS3 series, high-performance, small-format SiC mosfets for industrial equipment applications.

The two products have rated currents of 3300 V and 800 A respectively. The new product uses 3rd generation silicon carbide (SiC) and SBD (Schottky Barrier Diode) MOSFET chips. This helps reduce conduction losses with Switching loss when turned on is only 230 mJ and switching loss when turned off is only 230 mJ. With all the above advantages, MG800FXF1ZMS3 and MG800FZF1JMS3 bring optimization in performance and reduced size for the entire system, suitable for applications in industrial equipment, motor control equipment, generation systems. renewable energy electricity, and inverters and converters for rail vehicles.
