SiC Power Devices

Silicon carbide (SiC) is a semiconductor material with a high electric breakdown field, saturated electron velocity, and thermal conductivity, compared to silicon (Si). Therefore, when used in semiconductor devices, they achieve higher voltage resistance, higher-speed switching, and lower ON-resistance compared to Si devices. This is expected to be a next-generation low-loss device that contribute to lower power consumption and system downsizing.

Lineup

SiC MOSFETs
Toshiba’s 1200V SiC MOSFETs offers high-speed switching and low ON-resistance making it excellent for high-power, high-efficiency industrial power supplies, low-loss solar inverters and UPS.
SiC Schottky Barrier Diodes
Toshiba offers 650-V silicon carbide Schottky barrier diodes (SiC SBDs) with a rated current of 2 A to 10 A.
SiC MOSFETs Modules
Our SiC MOSFETs modules have high-speed switching properties, and use SiC (silicon carbide), a new material optimized for low-loss and miniaturization of power converters for the industry, such as inverters and converters for railway vehicles and photovoltaic inverters.
3rd generation Silicon Carbide(SiC) MOSFETs
Toshiba's 3rd generation Silicon Carbide (SiC) MOSFETs introduces a selection of both 650V and 1200V voltage products. In common with 2nd generations, Toshiba's newest generation of MOSFETs include a built-in SiC Schottky Barrier Diode (SBD) with a low forward voltage (VF) of -1.35V (typ.), placed in parallel with the PN diode in the SiC MOSFETs, to suppress fluctuation in RDS(on) thereby enhancing reliability. Furthermore, Toshiba’s advanced SiC process[1] has greatly improved our on-resistance per unit area RonA, and the performance index Ron*Qgd, which indicates switching characteristics, compared to 2nd generation products. Also, it has easy to design gate drive circuit, and you can prevent malfunctions due to switching noise.
Toshiba's 3rd generation SiC MOSFETs provides lower power consumption and supports higher power density for applications such as switching power supplies (servers for data centers, communication equipment, etc.), uninterruptible power supplies (UPS), PV inverters, EV charging stations, etc.
3rd generation Silicon Carbide(SiC) MOSFETs
Features of SiC MOSFET Modules
Our SiC MOSFET modules achieve high reliability, wide gate-to-source voltage, and high gate threshold voltage. In addition, the high heat tolerance and low inductance package brings out the performance of SiC sufficiently.
Features of Toshiba SiC MOSFET Modules
Compared to IGBT module, the low-loss characteristics of SiC MOSFET module can reduce the total loss (switching loss + conduction loss). High-speed switching and low-loss operation also reduce the size of the filter and transformer and heat sink, enabling a compact, lightweight system.
Improved JBS structure to reduce the leakage current and increase the surge current capability
The improved JBS structure has been applied to improve the leakage current of the SBD and the surge current capacity.
Diodes / SiC Schottky Barrier Diodes
High withstand voltage (reverse voltage) characteristics of SiC SBDs
A device with a high breakdown voltage has been realized with dielectric breakdown field strength nearly 10 times higher than that of Si.
