KAWASAKI, Japan — Toshiba Electronic Devices & Storage Corporation (“Toshiba”) has launched three 650V silicon carbide (SiC) MOSFETs equipped with its latest[1]3rd generation SiC MOSFET chips and housed in surface-mount TOLL packages. The new devices are suitable for industrial equipment, such as switched-mode power supplies and power conditioners for photovoltaic generators. Volume shipments of the MOSFETs, “ TW027U65C,” “ TW048U65C,” and “ TW083U65C,” start today.

The new products are Toshiba’s 3rd generation SiC MOSFETs in a general-purpose surface-mount TOLL package, which reduces device volume by more than 80% compared to through-hole packages such as TO-247 and TO-247-4L(X), and improves equipment power density.

The TOLL package also offers lower parasitic impedance[2] than through-hole packages, which helps to reduce switching losses. As a 4-terminal[3] package, a Kelvin connection can be used as the signal source terminal for the gate drive. This reduces the influence of inductance in the source wire within the package, achieving high-speed switching performance; in the case of TW048U65C, turn-on loss and turn-off loss are approximately 55% and 25%[4] lower, respectively, than in current Toshiba products[5], which will contribute to lower equipment power loss.

Toshiba will continue to expand its lineup to contribute to improved equipment efficiency and increased power capacity.

Features
Article content
- Surface-mount TOLL package: Enables equipment miniaturization and automated assembly. Low switching loss.
- Toshiba’s 3rd generation SiC MOSFETs:
– Optimization of drift resistance and channel resistance ratio realizes good temperature dependence of drain-source On-resistance.
– Low drain-source On-resistance×gate-drain charges
– Low diode forward voltage: VDSF=-1.35V(typ.) (VGS=-5V)
