Toshiba Launched 3300V SiC MOSFET Module
The new 800A power module integrates third-generation silicon carbide technology to improve thermal and electrical efficiency.
Updated on Sept. 24, 2026 in Semiconductors
Toshiba has launched the IX800FXF2YMS4, a new silicon carbide (SiC) MOSFET module designed for high-power industrial equipment. The component is now available for integration into systems requiring high voltage tolerance and switching efficiency.
Why it matters
Industrial power systems demand smaller, more efficient modules capable of sustaining higher temperatures and surge currents. This release addresses those reliability constraints by leveraging advanced material bonding and updated semiconductor architectures.
The module achieves a typical drain-source on-voltage of 1.4V, with switching losses measured at 185mJ (turn-on) and 175mJ (turn-off). It supports a maximum channel temperature of 175°C and offers a diode surge current capability of 300kAs.
The players
Toshiba
A Japanese conglomerate specializing in the research, design, and manufacturing of high-power semiconductor devices and infrastructure components.
The details
The IX800FXF2YMS4 utilizes third-generation silicon carbide (SiC) MOSFET chips—power transistors made from a compound of silicon and carbon that allows for higher voltage operation and faster switching than standard silicon. To manage the resulting thermal load, Toshiba employs silver sintering bonding—a process where silver particles are fused at high pressure and heat to create a highly conductive and heat-resistant electrical connection. The internal circuitry is housed in the company’s proprietary iXPLV package design, optimized for high-power density environments.

The Tech Race
This module represents the latest iteration of third-generation silicon carbide chips as manufacturers compete to push power density and voltage ceilings in industrial electronics. Toshiba remains focused on scaling this lineup to replace traditional silicon-based solutions in high-efficiency power architectures.
Industrial hardware manufacturers can expect improved thermal efficiency and reliability in power-intensive applications once these modules are integrated into future system designs. Availability timelines for specific product lineups will depend on individual industrial design cycles and procurement schedules.
The takeaway
The move to silver sintering and third-generation SiC architecture signals an industry-wide transition toward higher thermal thresholds for power electronics. Engineers should watch for future announcements regarding the expansion of this module lineup, which will likely dictate the next wave of high-power industrial efficiency standards.
