Toshiba Electronic Devices & Storage Corporation has started mass production of a 3rd generation silicon carbide (SiC) 1700 V and drain current (DC) rating 250 A of SiC MOSFET module “MG250V2YMS3” for industrial equipment and has expanded its lineup.

The new product MG250V2YMS3 offers low conduction loss with low drain-source on-voltage (sense) of 0.8 V (typ.). It also offers low switching loss with low turn-on switching loss of 18 mJ (typ.) and low turn-off switching loss of 11 mJ (typ.). This helps to reduce power loss of equipment and the size of cooling device.

MG250V2YMS3 has a low stray inductance of 12 nH (typ.) and is capable of high-speed switching. In addition, it suppresses surge voltage in switching operation. Thus, it is available for high frequency isolated DC-DC converter.

Toshiba’s SiC MOSFET module of 2-153A1A package has a lineup of four existing products, MG250YD2YMS3 (2200 V / 250 A), MG400V2YMS3 (1700 V / 400 A), and MG600Q2YMS3 (1200 V / 600 A), including new products. This provides a wider range of product selection.

Toshiba will continue to meet the needs for high efficiency and the downsizing of industrial equipment.
