ROHM Launches New Top-side Cooling Package for SiC MOSFETs, Combining High Heat Dissipation with High Voltage Support

Published

on

KYOTO, Japan, June 10, 2026 /PRNewswire/ — ROHM Co., Ltd. has developed the TSC3PAK (14.00 x 18.58 x 3.50 mm) package for SiC MOSFETs. By adopting a top-side heat dissipation structure that places the heat dissipation surface on the top of the package, the new product enables automated mounting while achieving heat dissipation performance comparable to that of conventional through-hole packages (TO-247-4L). This contributes to greater efficiency and reliability in power conversion circuits for onboard chargers (OBCs) and electric compressors used in xEVs (electric vehicles).

In xEVs, the adoption of SiC devices is expanding beyond main inverters to include power conversion circuits such as OBCs and electric compressors to improve charging speed and extend cruising range.

Through-hole type devices involve manual mounting processes, and their form factor makes it difficult to achieve a lower package profile. Surface-mount SiC devices compatible with automated mounting have begun gaining adoption. To address these issues, the new TSC3PAK delivers heat dissipation performance comparable to through-hole technology such as TO-247 in a surface-mount package.

The new package incorporates ROHM’s proprietary groove structure to secure a long creepage distance of 6.66 mm, allowing it to accommodate an AC peak voltage of 1200 V in a Pollution Degree 2 environment while maintaining compatibility with products widely adopted in the market.

Products using the new package incorporate ROHM’s 4th Generation SiC MOSFETs, achieving low ON resistance and high-speed switching characteristics. As a result, switching losses during power conversion are significantly reduced, contributing to greater application efficiency and lower power consumption.

Mass production started in June 2026. For more details, please visit the contact page on ROHM’s website.

By

XIAMEN, China, Nov. 13, 2026 /PRNewswire/ — The inaugural Global Energy Storage Colloquium was held in Xiamen under the theme “Frontiers in Dialogue•Powering Tomorrow’s Storage.” Hosted by HiTHIUM and co-organized by the Energy Storage Application Branch of China Industrial Association of Power Sources (CESA), the colloquium brought together leading international experts, scholars, and industry representatives. Participants discussed battery materials, energy storage technologies, power electronics, system applications and industrial innovation.

As energy storage develops toward longer durations, diverse technologies, larger capacity and greater system integration, the industry faces scientific and technical challenges involving battery materials, lifetime mechanisms, safety limits and power system integration. The colloquium provided a platform for experts to exchange views on these topics and explore how fundamental research and international collaboration can support continued innovation.

Participants came from Imperial College London, the University of Cambridge, Tsinghua University, Xiamen University, Huazhong University of Science and Technology, City University of Hong Kong and other institutions. Maochun Hong, Academician of the Chinese Academy of Sciences from the Fujian Institute of Research on the Structure of Matter, attended the event. Clare Grey, Dame Commander of the Order of the British Empire, Professor of Chemistry, University of Cambridge; Tim Green, Fellow of the Royal Academy of Engineering and Professor at Imperial College London; Shigang Sun, Academician of the Chinese Academy of Sciences and Professor at Xiamen University; Yong Yang, Distinguished Professor at Xiamen University; and Chongqing Kang, Professor at Tsinghua University served as co-chairs. Yunhui Huang, Professor at Huazhong University of Science and Technology served as chief advisor.

Jeff Wu, Founder and Chairman of HiTHIUM; Yong Liu, Vice Chair of CESA; and Kate Harrisson, His Majesty’s Trade Commissioner for China and Hong Kong, delivered remarks at the Colloquium.

According to Jeff Wu, energy storage is a systemic technology spanning multiple disciplines and sectors, and that its development depends on breakthroughs in fundamental research and international collaboration. He said HiTHIUM hopes to build on the colloquium to expand cooperation with leading universities and research institutions worldwide, deepen engagement between academia and industry, and help translate research into practical contributions. The company will continue supporting the colloquium as a lasting platform for exchange and collaboration.

Academic sessions covered battery mechanisms and characterization, degradation and lifetime prediction for grid-scale lithium-ion batteries, power system stability with high penetration of inverter-based resources, and the development of virtual power plants. Experts also discussed real-time, non-destructive battery testing, early warning of thermal runaway, energy storage opportunities at distribution transformer areas, and revenue streams from electricity market participation.

The three-day colloquium also included thematic sessions on energy storage materials and batteries, power and grids, systems and applications. Scholars visited HiTHIUM’s smart factory in Xiamen to learn about advanced manufacturing and industrial practices in China’s energy storage sector.

HiTHIUM looks forward to working with partners worldwide to advance energy storage technology and the industry’s development, supporting the global energy transition and a clean, sustainable future.

Guangdong and Papua New Guinea: Taking roots across the Pacific

Published

on

By

GUANGZHOU, China, Nov. 13, 2026 /PRNewswire/ — A news report from South:

Few places on Earth feel as wild as Papua New Guinea. Spread across more than 600 islands, the Pacific nation is home to extraordinary cultural and biological diversity. But some of what comes from its waters is now travelling much further—all the way to dinner tables in China.

For local seafood exporter Tony Lan, China has transformed the scale of his business. His company buys wild-caught mud crabs from local fishermen before flying them to Chinese cities including Guangzhou.

“We used to sell a few hundred kilos a week to the local market,” Lan said. “But once we started exporting crabs to China, business just exploded. Now we’re moving 20 to 30 tons a week.”

The impact has spread beyond the company itself. Lan said families involved in the crab trade have been able to build better homes and buy televisions and generators.

But the connections between Papua New Guinea and Guangdong go far beyond seafood.

In Port Moresby, 21-year-old Maureen works as a receptionist for a Chinese company. Finding work is far from guaranteed. “A lot of degree holders, they don’t have jobs,” she said. “But you see me, I don’t have a degree, but I have a job.”

Her story leads back to Butuka Academy, the school she graduated from. Built with support from Shenzhen under its sister-city relationship with Port Moresby, the academy now accommodates around 3,000 students. Maureen says the computer skills she learned there—including Microsoft applications, web skills and Excel—are the same ones she now uses at work.

Another connection has taken root in soil.

Juncao, a grass-based agricultural technology developed in China, was introduced to Papua New Guinea in the 1990s. Initially used for mushroom cultivation, it has since found applications ranging from livestock feed to fibers and bioenergy. Over three decades, the technology has spread to more than 9,000 farming households, benefiting around 30,000 people.

For Georgina, whose family was among the early adopters, Juncao has shaped both family life and career. After struggling to find a job for two years, she returned to mushroom farming and helped local farmers find markets. That experience eventually led to her current work with a Shenzhen company exploring new uses for the grass.

“I want everyone to know about Juncao, the benefits of it,” she said. “It’s part of me.”

For National Capital District Governor Powes Parkop, such exchanges are part of Papua New Guinea’s wider development journey.

“Being a rural-based, traditional economy, now trying to become a modern economy, we can only learn from China,” Parkop said. He also stressed the importance of APEC for smaller economies, saying PNG does not always have the means to engage with economies across the Pacific individually, “and we have the opportunity at APEC.”
