SUNNYVALE, Calif.--(BUSINESS WIRE)--May 1, 2025--
Alpha and Omega Semiconductor Limited (AOS) (Nasdaq: AOSL) a designer, developer, and global supplier of a broad range of discrete power devices, wide bandgap power devices, power management ICs, and modules, today introduced the company’s next generation (Gen3) 1200V αSiC MOSFETs designed to maximize efficiency in a growing market of high power applications. These Gen3 MOSFETs provide up to 30 percent improved switching figure-of-merit (FOM) compared to AOS’ previous generation while maintaining low conduction losses at high load conditions. The performance improvements do not compromise ruggedness and reliability, as the Gen3 MOSFETs have full AEC-Q101 qualification, with extended lifetime and HV-H3TRB capabilities.

As power demands surge in electric vehicles (EVs), AI data centers, and renewable energy systems, inefficiencies in power conversion stages can significantly strain electrical supply and cooling systems. For EV designs, AOS’ Gen3 αSiC MOSFETs enable engineers to create higher power density systems with greater efficiency, reducing battery consumption and extending vehicle range. Future AI data centers adopting high-voltage DC (HVDC) architectures, such as 800V or ±400V, will benefit from reduced losses and increased power density to meet growing power requirements. To support these higher system voltages, AOS’ Gen3 1200V devices will be critical for enabling new topologies with the necessary efficiency.
The new AOS Gen3 1200V MOSFETs are available with an on-resistance (Rds(on)) range from 15mOhm (AOM015V120X3Q) to 40mOhm (AOM040V120X3Q) in a TO27-4L package. AOS plans to roll out its Gen3 MOSFETs in additional surface mount and topside cooled packages as well as in case modules. AOS has also qualified a larger Gen3 1200V/11mOhm MOSFET die designed for high-power EV traction inverter modules and is available for wafer sales.
“Electric vehicles and AI are transforming industries, but they require advanced power systems that can maintain efficiency even as energy demands increase,” said David Sheridan, Vice President of Wide Bandgap products at AOS. “We’re excited that this next generation of AOS αSiC MOSFETs can deliver the performance our customers require while making a positive environmental impact.”

Alpha and Omega Semiconductor Introduces Gen3 1200V αSiC MOSFETs Designed to Maximize Efficiency in High Power Applications
MELBOURNE, Australia (AP) — Auckland was the first major city to ring in 2026 with a fireworks display launched from New Zealand’s tallest structure, Sky Tower, followed by a defiant celebration in Australia in the aftermath of its worst mass shooting.
South Pacific countries were the first to bid farewell to 2025. Clocks stuck midnight in Auckland 18 hours before the famous ball drop in New York’s Times Square. The five-minute display involved 3,500 fireworks.
Australia’s east coast welcomed 2026 two hours after New Zealand. In Sydney, the country's largest city, celebrations were held under the pall of Australia’s worst mass shooting in almost 30 years. Two gunmen targeted a Hannukah celebration at Bondi Beach on Dec. 14, killing 15 and wounding 40.
A heavy police presence monitored the thousands who thronged to the waterfront to watch a fireworks show centered on the Sydney Harbor Bridge. Many officers openly carried rapid-fire rifles, a first for the annual event.
An hour before midnight, the massacre victims were commemorated with a minute of silence while images of a menorah were projected on the bridge pylons. The crowd was invited to show solidarity with Australia’s Jewish community.
New South Wales Premier Chris Minns urged Sydney residents not to stay away through fear, saying extremists would interpret smaller crowds at New Year’s Eve festivities as a victory.
“We have to show defiance in the face of this terrible crime and say that we’re not going to be cowered by this kind of terrorism,” he said.
In Indonesia, one of Australia’s nearest neighbors, cities scaled back festivities as a gesture of solidarity with communities devastated by floods and landslides that struck parts of Sumatra island a month ago, claiming more than 1,100 lives.
The capital, Jakarta, was not ringing in 2026 with its usual fanfare, choosing subdued celebrations with a program centered on prayers for victims, city Gov. Pramono Anung said last week.
Makassar Mayor Munafri Arifuddin urged residents of one of Indonesia’s largest cities to forgo parties, calling for prayer and reflection. "Empathy and restraint are more meaningful than fireworks and crowds,” he said.
Concerts and fireworks on Indonesia’s tourist island of Bali were canceled and replaced with a cultural arts event featuring traditional dances.
Hong Kong, too, was ringing in 2026 without the usual spectacle in the sky over iconic Victoria Harbor, after a massive fire in November killed at least 161 people.
The facades of eight landmarks were turning into giant countdown clocks presenting a three-minute light show at midnight.
Many parts of Asia welcome the new year by observing age-old traditions.
In Japan, crowds were gathering at a Buddhist temple in Tokyo for a bell striking at midnight. In the South Korean capital, Seoul, a bell tolling and countdown ceremony were being held at the Bosingak Pavilion.
Tourists and Berliners alike marked the end of 2025 by enjoying snowfall, taking selfies and making snowmen in front of the German capital's cathedral and the iconic Brandenburg Gate. The Berlin TV Tower was nearly invisible thanks to the falling flakes and fog.
Greece and Cyprus were ringing in 2026 by turning down the volume, replacing traditional fireworks with low-noise pyrotechnics, light shows and drone displays in capital cities. Low-noise fireworks avoid the explosive bursts that generate the loud cracks of traditional displays.
Officials in the countries said the change is intended to make celebrations more welcoming for children and pets, particularly animals sensitive to loud noise.
Police in New York City will have additional anti-terrorism measures at the Times Square ball drop, with “mobile screening teams” in search of suspicious activity. It is not in response to a specific threat, according to NYPD Commissioner Jessica Tisch.
After the ball drops in Times Square, it will rise once again, sparking in red, white and blue, to mark the country’s upcoming 250th birthday celebration. It will be one of several patriotic flourishes throughout the night, organizers said.
Zohran Mamdani will take office as mayor at the start of 2026. Two swearing-in ceremonies are planned, starting with a private ceremonial event around midnight in an old subway station.
