Toshiba launches third generation 650V silicon carbide (SiC) MOSFETs

Toshiba Electronics Europe has launched a total of five new third-generation 650V silicon carbide (SiC) MOSFET devices for industrial equipment.

Highly efficient and versatile, these products will be used in a variety of demanding applications including switch mode power supplies (SMPS) and uninterruptible power supplies (UPS) for servers, data centres and communication equipment. They will also find applications in renewable energy, including photovoltaic (PV) inverters and bi-directional DC-DC converters, such as those used for electric vehicle (EV) charging.

The TW015N65C, TW027N65C, TW048N65C, TW083N65C and TW107N65C are based upon Toshiba’s advanced third generation SiC process which optimises the cell structures used in second-generation devices.

As a result of this advancement, a key figure of merit (FoM) calculated as the product of drain-source on-resistance (RDS(on)) and gate-drain charge (Qg) to represent both static and dynamic losses has improved by about 80%. This significantly reduces losses and allows power solutions with higher power densities and lower running costs to be developed.

In common with earlier devices, these third-generation MOSFETs include a built-in SiC Schottky barrier with a low forward voltage (VF) of -1.35V (typ.) to suppress fluctuation in RDS(on), thereby enhancing reliability.

The new devices are able to handle currents (ID) up to 100A and feature RDS(on) values as low as 15mΩ. All devices are housed in an industry standard TO-247 package.
