Toshiba Starts Shipping Test Samples of 1200V Trench-Gate SiC MOSFET that will Enhance Efficiency in Next-Generation AI Data Centers

KAWASAKI, Japan--(BUSINESS WIRE)--May 20, 2026--

Toshiba Electronic Devices & Storage Corporation ("Toshiba") today started shipping test samples of “TW007D120E,” a 1200V trench-gate SiC MOSFET primarily intended for power supply systems in next-generation AI data centers that is also suitable for use in renewable energy-related equipment.

With the rapid expansion of generative AI, increasing power consumption has become a pressing issue for data centers. In particular, the widespread adoption of high-power AI servers and the growing deployment of 800V high-voltage direct current (HVDC) architectures are driving demand for power supply systems with higher power conversion efficiency and power density. Toshiba has addressed these requirements for next-generation AI data centers by developing TW007D120E, which will contribute to lower power consumption and to the miniaturization and higher efficiency of power supply systems.

TW007D120E is built around Toshiba’s proprietary trench-gate structure [1], which achieves industry-leading [2] low On-resistance per unit area (R DS(on) A); it reduces conduction loss through lower On-resistance while simultaneously achieving lower switching loss. Compared with Toshiba’s current products, TW007D120E reduces R DS(on) A by approximately 58% [3] and improves the figure of merit, On-resistance × gate-drain charge (R DS(on) × Q gd ), which represents the trade-off between conduction loss and switching loss, by approximately 52% [3]. These characteristics will help to realize highly efficient operation and reduced heat generation in data center power supply systems and contribute to improved overall system efficiency.

The new product is housed in a QDPAK package that supports top-side cooling. This contributes to both higher power density implementation and enhanced thermal performance in the power stage, which are essential for power conversion in next-generation AI data centers.

Toshiba will prepare for mass production of TW007D120E during fiscal year 2026 and will continue to expand its lineup, including development for automotive applications. Through the trench-gate SiC MOSFET, the company will contribute to improved power efficiency and reduced CO₂ emissions in data centers and a wide range of industrial equipment, supporting the realization of a decarbonized society.

TW007D120E is based on results obtained from JPNP21029, a project subsidized by the New Energy and Industrial Technology Development Organization (NEDO).

PHOENIX (AP) — Two Phoenix police officers were fired and arrested after an unreported traffic stop in which they assaulted a man and woman and shocked them with a Taser, the police chief said.

Officers Antonio Felix and Luis Vasquez were arrested on charges including aggravated assault and kidnapping, police chief Matt Giordano said at a news conference Saturday.

“Detectives have confirmed that the two former officers physically assaulted both the man and woman during the traffic stop,” Giordano said. “The investigation also shows that a Taser was used on the victims during the stop.”

The officers did not report the Aug. 5 traffic stop and did not activate their body-worn cameras, police said.

“There is no video evidence, but we established what we believe is probable cause that these crimes were committed,” Giordano said, adding there was no indication that the officers knew the victims.

Dave Evans, a spokesperson for the Maricopa County Sheriff’s Office, said Sunday that Vasquez had been released from custody while Felix remained incarcerated at the Lower Buckeye Jail in Phoenix.

Attempts by The Associated Press to determine who their defense attorneys were to request comment were unsuccessful.

During the late-night traffic stop in Phoenix, the male driver and woman passenger reported that the officers smashed the car window, according to a statement from Phoenix police. Vasquez punched the man and threatened to shoot him, while the woman was removed from the vehicle and handcuffed.

The man managed to drive away and abandoned the car in neighboring Tempe, while the woman was released at the scene, the statement said.

A police officer in neighboring Tempe who responded to the abandoned car asked over dispatch whether it had fled from any neighboring police agencies and was told it had not, according to a Tempe police report.

The Tempe officer called the car's registered owner, the mother of the male driver, and through her was able to connect with the woman passenger and eventually the male driver. The woman passenger told the officer that both of them had been shocked with a Taser, while the man later told the officer that he had been punched in the face multiple times and that they had repeatedly asked why they had been stopped.

The Tempe officer wrote in the report that he believed they were victims of an attempted carjacking by people impersonating police officers.

Giordano, the Phoenix police chief, said he had a similar reaction when he initially learned of the incident as it was “so far outside the bounds of our policies.” But when detectives started looking into it, they realized Phoenix officers might be involved and transitioned the case to a special investigations detail, he said.

“That's when they started putting evidence together, including the automatic vehicle locator that did put a vehicle at that location about the time that the victims reported it occurred," Giordano said, referring to the location technology in city vehicles.

Vasquez and Felix had served eight and nine years with Phoenix police, respectively. Giordano, without elaborating, said both had previously violated department policy but that it was “nothing of this nature.”

The Phoenix department's investigation and audit are ongoing. The officers have a scheduled court date on Friday.
