NoMIS Power Demonstrates 6.5 kV SiC MOSFET, Advancing a High-Voltage Roadmap to 10 kV and 20 kV SiC IGBTs

Initial 6.5 kV silicon carbide (SiC) results — over 8 kV blocking, 90 mΩ, 55 A — establish NoMIS Power as a U.S. source of high-voltage SiC devices, with a roadmap toward 10 kV SiC MOSFETs and 20 kV SiC IGBTs.

ALBANY, N.Y., Aug. 6, 2026 /PRNewswire/ -- NoMIS Power Corporation, a leader in advanced Silicon Carbide (SiC) power semiconductor technology, today announced a major high-voltage milestone: the successful demonstration of its first 6.5 kV large-die SiC MOSFET. The device was measured at over 8 kV blocking, 90 mΩ on-resistance, and 55 A drain current. The result carries NoMIS Power's proven planar SiC device technology from its established 3.3 kV devices into the high-voltage class, and establishes a clear, demonstrated path toward the company's forthcoming 10 kV MOSFETs and 20 kV SiC IGBTs.

A U.S.-designed SiC roadmap: shipping today and demonstrated for tomorrow

NoMIS Power's high-voltage SiC roadmap spans three stages — 3.3 kV in production and 6.5 kV sampling, with 10 kV in development:

"Demonstrating 6.5 kV blocking to over 8 kV proves our planar SiC platform scales cleanly from the 3.3 kV devices shipping today into the high-voltage class," said Dr. Adam Morgan, Co-Founder and CEO of NoMIS Power. "High-voltage SiC is becoming foundational to data-center, grid, aerospace, and defense power systems, and it should be built at home — we're building the domestic source the industry can qualify against, from 3.3 kV and 6.5 kV today to 10 kV MOSFETs and 20 kV SiC IGBTs on our roadmap."

A U.S.-based, domestic source of high-voltage SiC

For programs dependent on a single supplier of high-voltage SiC, NoMIS Power offers a domestic alternative. The company's devices are U.S.-designed, ITAR- and DFARS-aware, and available through various foundry options, and its SiC is already specified into U.S. government-funded programs such as U.S. Department of Energy and Department of War programs. The company supports device qualification and design-in — including form-fit-function-compatible devices and support for existing high-voltage SiC platforms — to reduce single-source risk and strengthen continuity of supply for mission-critical programs. NoMIS Power designs SiC devices, packaging, and power modules at its facility within the Albany Nanotech Complex in Albany, New York.

Availability and engagement

The 6.5 kV large-die SiC MOSFET is sampling now to U.S.-based customers for evaluation, with standard production parts scheduled for Q4 2026. NoMIS Power is engaging system developers on design-in, custom current ratings, and packaging. Teams evaluating high-voltage SiC for HVDC, solid-state transformers, pulsed power, traction, high-power charging, or aerospace and defense platforms can contact NoMIS Power to align to the 6.5 kV, 10 kV, and 20 kV roadmap.
