Toshiba launches 650V third generation SiC MOSFETs in compact TOLL package
Toshiba Electronics Europe has released three new 650V silicon carbide (SiC) MOSFETs, which constitute its latest third generation SiC MOSFET chips. The TW027U65C, TW048U65C and TW083U65C are housed in a surface-mount TOLL package
) for direct CO2 measurement, the STCC4 set to transform how
society monitors indoor air quality. Utilizing the latest technological advancements in thermal conductivity sensing, the STCC4 provides the accuracy needed for indoor air quality applications.
Both accurate signal compensation and monitoring of relevant indoor environmental parameters are achieved when STCC4 is combined with Sensirion’s industry-leading temperature and humidity sensors. Engineered and manufactured in Switzerland, it has been optimised for easy integration into high volume applications through its SMD design and tape & reel packaging.
The SEK-STCC4 evaluation kit jumpstarts the sensor assessment process by offering users a straightforward testing approach. Sensirion enables simple sensor evaluation through provided hardware, software testing platform and driver support. Other features of the STCC4 CO2
include avg. current consumption possibility below
100µA for low power applications, and accuracy of ±(100 ppm + 10%). The STCC4 is suitable for a wide range of applications, including indoor air quality monitors, smart thermostats, air conditioners and much more.

and are designed to reduce switching losses in industrial equipment. They are suitable for a wide range of demanding power applications, including switched-mode power supplies (SMPS) in servers, data centres and communications equipment, uninterruptible power supplies (UPS), EV charging stations, and power conditioners for photovoltaic (PV) inverters.
Compared to lead-inserted packages, such as the TO-247 and TO-247-4L(X), these new devices significantly reduce volume by more than 80%. This substantial miniaturisation directly contributes to improved equipment power density. Furthermore, the surface mounting capability of the TOLL package allows for the use of smaller parasitic impedance components, including resistors and inductors, which in turn leads to a reduction in switching losses.
The TOLL package is a 9-pin, 4-terminal package designed to facilitate the use of a Kelvin connection for its signal source terminal for the gate drive. This advanced design minimises the influence of inductance in the source wire within the package, thereby achieving high-speed switching performance. For example, the TW048U65C demonstrates a notable reduction in turn-on loss (Eon) of approximately 55% and turn-off loss (Eoff) of around 25% compared to Toshiba’s equivalent product that uses the TO-247 package without a Kelvin connection. This improvement directly contributes to reducing power loss in equipment.
