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 SiC MOSFETs TO-247-4L
Compared to Si (silicon) IGBTs and MOSFETs, which are currently mainstream, power MOSFETs using SiC (silicon carbide) not only excel in low conduction loss and operation in high-temperature environments, but also contribute to low-loss application through high-speed switching. TO-247-4L(X), a new package for our 3rd generation SiC MOSFETs, is a 4-terminal type, and by reducing the influence of the inductance of the source wire inside the package, it is possible to draw out high-speed switching performance. This contributes to lower loss in applications such as servers, uninterruptible power supplies (UPS), and Photovoltaics Inverter.
