KAWASAKI, Japan — Toshiba Electronic Devices & Storage Corporation (“Toshiba”) has launched four 650V silicon carbide (SiC) MOSFETs, equipped with its latest[1]3rd generation SiC MOSFET chips and housed in a compact DFN8x8 package, suitable for industrial equipment, such as switched-mode power supplies and power conditioners for photovoltaic generators. Volume shipments of the four devices, “ TW031V65C,” “ TW054V65C,” “ TW092V65C,” and “ TW123V65C,” start today.

Article content
The new products are the first 3rd generation SiC MOSFETs to use the small surface-mount DFN8x8 package, which reduces volume by more than 90% compared to lead-inserted packages, such as TO-247 and TO-247-4L(X) and improves equipment power density. Surface mounting also allows use of parasitic impedance[2] components smaller than those of lead-inserted packages, reducing switching losses. DFN8x8 is a 4-pin[3] package, allowing use of a Kelvin connection of its 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 TW054V65C, it reduces turn-on loss by approximately 55% and turn-off loss by approximately 25%[4] compared to current Toshiba products[5], helping to reduce power loss in equipment.
