TRENCHSTOP™ 5 WR6 Family in TO-247-3-HCC Housing

Infineon Technologies AG introduces the new 650 V TRENCHSTOP™ 5 WR6 family in a discrete housing. The family comes in a TO-247-3-HCC package and offers a broad portfolio comprising 20 A, 30 A, 40 A, 50 A, 60 A and 70 A current ratings. The devices can easily be used for replacing previous technologies like Infineon’s TRENCHSTOP 5 WR5 and HighSpeed 3 H3 as well as competitor technologies. The family is optimized for power factor correction (PFC) for residential and commercial air conditioning systems as well as welding applications.

The TRENCHSTOP 5 WR6 switches provide very low conduction losses (30 A, 1,45 V at 25°C) as well as lowest switching losses (30 A, 1,55 mJ at 175°C). They feature a very low saturation voltage (V CE(sat)) of 1,45 V and a monolithically integrated diode with optimized forward voltage for the target applications. This results in best-in-class performance while enabling a low BOM cost. Additionally, the device leverages the performance advantage of the TRENCHSTOP 5 WR5 series, the predecessor to the TRENCHSTOP 5 WR6 series.

The new TO-247-3-HCC housing of the WR6 family increases the creepage and clearance distances thus improving the isolation voltage rating. With this, the product family enables more reliable system designs that are resistant against contamination and condensation which e.g. often occur at AC outdoor units. The TRENCHSTOP 5 WR6 reduces the total cost of ownership with less failure rate while it also enables higher switching frequency in application.

After BYD, Another Chinese Company to Mass Produce Automotive IGBTs

As a key component of new energy vehicles, IGBT is regarded as the core technology peak due to its difficult technology and a large investment. Now, after BYD, another Chinese company is going to mass-produce this product.

Shanghai Huahong Grace Semiconductor Manufacturing Corp, a foundry, and Starpower, a leader in China’s IGBT industry, held a “Huahong Automotive IGBT and 12-inch IGBT mass production ceremony” and signed a strategic cooperation agreement.

The two sides will work together to build high-power automotive-grade IGBT chips, which have now passed product validation by car companies and are entering the market for automotive applications such as power units, according to the company.

Huahong has successfully established its IGBT wafer production process on a 12-inch production line and its products have passed customer certification, making it the first pure-play foundry in the world to mass-produce advanced trench gate electric field cutoff IGBTs on both 8-inch and 12-inch production lines, the company said.

The company said its 12-inch IGBT output has exceeded 10,000 wafers. Last year, Starpower produced automotive-grade IGBT modules for more than 200,000 new energy vehicles.

IGBT, or insulated gate bipolar transistor, is a key technology that affects the performance of electric vehicles and is the “brain” of new energy vehicles, accounting for about 5 percent of the cost of the vehicle.

The technology has been mastered in Japan, Europe, and other foreign manufacturers for many years until BYD emerged to bring China out of this dilemma.


It is worth noting that although IGBT is the current technology used by mainstream car manufacturers, Tesla, BYD, and NIO have started to introduce the more advanced silicon carbide (SiC) technology.

Tesla and BYD have already started using Sic MOSFETs (silicon carbide power field-effect transistors) in their Model 3 and Han EV models.

NIO announced on June 22 that the first silicon carbide electric drive system C prototype, a volume prototype for process and production test verification, has rolled off the production line.

As a product of NIO’s second-generation electric drive platform, this electric drive system is more efficient, compact and lightweight, and is an advanced technology in current electric vehicle manufacturing.

After the mass production of this technology, it will be firstly equipped by NIO’s first sedan product, ET7, to provide a longer range for the vehicle.

In the field of new energy vehicles, silicon carbide is mainly used in the power control unit, which can be applied to the inverter that drives and controls the motor, vehicle charger, fast charging pile and other systems.

UK’s Largest Chip Plant to Be Acquired by Chinese-Owned Firm Nexperia

Newport Wafer Fab, the U.K.’s largest chip producer, is set to be acquired by Chinese-owned semiconductor company Nexperia for around £63 million ($87 million) next week.

Nexperia, a Dutch firm that is 100%-owned by China’s Wingtech Technology, told CNBC on Friday that the deal talks are ongoing.

Located in Newport, South Wales, privately-held NWF’s chip plant dates back to 1982 and it is one of just a handful of semiconductor fabricators in the U.K.

The deal comes during a global chip shortage that has led countries to try and become more independent when it comes to semiconductor production. The vast majority of today’s chips are manufactured in Asia, with Taiwan’s TSMC, South Korea’s Samsung and China’s SMIC among the largest chip producers in the world.

Hitachi ABB Power Grids is Evolving to Become Hitachi Energy

Hitachi ABB Power Grids that includes ABB Semiconductors business announced that it will be evolving to become Hitachi Energy from October 2021. The decision to change name has board and shareholder consent and coincides with the business’ first-year anniversary since it started operations on 1 July, 2020. Hitachi Ltd. has an 80.1 percent stake in the joint venture and ABB Ltd. holds the balance.

Headquartered in Zurich, Switzerland, the global technology and market leader brings a rich heritage of pioneering breakthroughs, which have helped to increase access to safe, secure, and reliable electricity for more than one century.
