Diodes launches automotive field-plated Super Barrier Rectifiers rated from 2 A to 8 A

Diodes Incorporated has introduced a family of field-plated Super Barrier Rectifier (SBRFP) devices for automotive use, including parts rated at 2 A, 3 A and 8 A. Diodes says the parts are drop-in replacements for comparable Schottky and PN junction diodes, and that their low forward voltage and reverse leakage suit DC-DC converters, reverse-polarity protection circuits, battery charging systems, automotive LED lighting and transmission control systems.

Diodes says its patented field-plated rectifier technology, built on a metal oxide semiconductor (MOS) manufacturing process rather than the metal-semiconductor junction of a conventional Schottky rectifier, overcomes the limitations of both Schottky and PN junction diodes.

The 8 A SBRFP8A60P5Q has a maximum forward voltage of 0.55 V at 8 A. A rectifier’s conduction loss is the product of its forward voltage and current, so a lower drop means less heat to remove at higher currents.

The 2 A SBRFP2M60P1Q and 3 A SBRFP3M60SAFQ have maximum reverse leakage currents of 12 µA and 7 µA, respectively, at 25° C and a 60 V reverse voltage, according to their data sheets. Schottky leakage climbs steeply with temperature, and Diodes says the low leakage helps minimize the risk of thermal runaway under high-temperature operating conditions.

Avalanche energy ratings reach up to 145 mJ, depending on the device. The data sheet lists that rating for the SBRFP2M60P1Q at an avalanche current of 2 A. Diodes puts the family’s avalanche capability at five to 10 times that of conventional Schottky rectifiers, which the company says lets the parts withstand surge events, load dumps and other transients common in automotive electrical systems.

The SBRFP2M60P1Q comes in a PowerDI123 package, the SBRFP8A60P5Q in PowerDI5 and the SBRFP2M60SAFQ and SBRFP3M60SAFQ in SMAF. All four operate across a junction temperature range of -55° C to +175° C.

In 1,000-piece quantities, pricing is $0.08 for the SBRFP2M60P1Q, $0.11 for the SBRFP2M60SAFQ, $0.13 for the SBRFP3M60SAFQ and $0.26 for the SBRFP8A60P5Q.

Scania to supply Core 800 battery packs for Prinoth’s electric snow groomers

Scania has signed a long-term agreement to supply its Core 800 battery packs to Italian snow groomer maker Prinoth, part of the High Technology Industries (HTI) Group. The packs will power two fully electric groomers: the Husky E-Motion and the Leitwolf E-Motion.

The agreement turns an existing collaboration into a long-term partnership. Prinoth introduced the Husky E-Motion in 2022, and Scania describes it as the world’s first market-ready fully electric snow groomer. The Core 800 has powered it since 2023, and the machine has been deployed in markets including Norway, France, Italy, the UK and the US.

“At Prinoth, we have chosen to continue our collaboration with Scania because of the high quality of their battery systems, which we have tested in some of the most challenging environmental conditions,” said Roberto Pegoraro, Prinoth’s Head of R&D Snow Groomers.

The Leitwolf E-Motion carries Core 800 packs in both top and side orientations, and Scania says the packs are configured to meet higher energy and power requirements. Prinoth launched the model in April 2026 and says it runs for approximately five hours under real working conditions and fast-charges from 10 to 80% in around one hour.

The Core 800 is a lithium-ion pack with 97 kWh of installed energy and a nominal voltage of 691 V. The pack is modular, so systems can scale from 21 kWh up to 624 kWh. It has integrated liquid cooling and a proprietary battery management system.

Scania’s industrial battery systems are also used in mining, construction, agriculture and logistics vehicles, as well as in energy storage and airport ground support equipment.

“Snow groomers operate in very low temperatures and steep terrain, moving heavy volumes of snow. This requires batteries that can deliver high power, withstand cold climates, and handle vibrations,” said Elin Åkerström, Managing Director of Scania Industrial Batteries.

Siemens Canada to develop a digital twin of Rock Tech’s Red Rock lithium converter

Rock Tech Lithium has signed agreements with Siemens Canada covering the Red Rock Lithium Converter, the lithium conversion plant Rock Tech plans to build in Ontario with capacity for up to 32,000 tonnes per year of lithium carbonate equivalent. Siemens will develop a digital process twin of the plant and support Rock Tech’s project team on the converter’s definitive feasibility study (DFS).

Rock Tech describes the twin as a virtual, physics-based model of the plant’s processes, energy flows and material streams that lets the company test, optimize and validate design choices, efficiency, emissions and operational reliability before major capital is committed. The first step is a digital process twin built on results from the DFS. The company plans for the technology to cover the project’s entire lifecycle, from the feasibility study through engineering and construction to operations.

The agreements are the first implementation phase under a memorandum of understanding the two companies signed in March 2026. That memorandum covers development and integration of Siemens digital twin technology, as well as evaluation of additional Siemens solutions, services and engineering support. Rock Tech says the goal is to position the Red Rock Converter as a blueprint for future converters in Canada and allied markets. The parties will also evaluate applying the cooperation to future projects in other G7 countries.

In Canada, Rock Tech’s feedstock sources include its wholly owned Georgia Lake Project. In July 2026, the company secured an option to acquire the Victory project, a lithium exploration property in Northwestern Ontario.

For the DFS, Siemens Canada will provide support in process control, instrumentation and automation architecture. Rock Tech launched the study at the end of June 2026 and expects to finalize it by mid-December 2026.

Neo Performance Materials starts commercial EV traction magnet production in Estonia

Neo Performance Materials’ permanent magnet plant in Estonia, opened in 2025, is in commercial production, and the first commercial volumes of rare earth sintered magnets have gone to a Tier 1 EV traction motor customer.

Three Tier 1 motor manufacturers have awarded Neo multiple magnet programs, including traction motor applications, and the company has delivered qualification samples for each. Neo calls traction motor magnets the most technically demanding category of permanent magnets. Neo shipped the plant’s first magnet samples to a traction motor customer in June 2025.

Traction rotors run their magnets hot and against high reverse fields, so the material has to resist irreversible demagnetization at temperature rather than simply deliver peak remanence on the bench. Qualifying a new plant for that duty means showing that magnetic properties, dimensional tolerance and coating adhesion repeat lot to lot, which is the work the sampling phase does before a production award.

Neo expects two to three programs to be producing commercially before the end of 2026, and further traction motor and accessory magnet programs are scheduled to launch later in 2026. Automotive magnet programs are usually awarded for the life of the vehicle platform they supply, so a single award carries several years of volume visibility.

Phase 1A of the facility has nameplate capacity of about 2,000 metric tonnes a year. Phase 1B would raise that to roughly 5,000 metric tonnes a year and is in design. Detailed engineering, equipment procurement, supply chain planning and facility layout are all under way.

Neo’s long-term plans include reaching 20,000 metric tonnes of annual production through continued global expansion, a figure the company estimates could account for 10% to 15% of the projected rare earth permanent magnet market outside China.

“We built this facility in under two years and have won multiple program awards from Tier 1 motor manufacturers,” said Rahim Suleman, Neo’s President and Chief Executive Officer.

Chinese rare earth groups and Anhui’s EV sector launch a joint magnet alliance

Five Chinese industry, research and government organizations signed a strategic cooperation agreement, launching the Anhui Rare Earth Industry Alliance. The signatories were the China Rare Earth Industry Association (CREIA), the Chinese Society of Rare Earths, the National Key Laboratory of Rare Earth Permanent Magnet Materials, the Baohe District government in Hefei and the Anhui New Energy and Intelligent Connected Vehicle Industry Development Association.

Sintered neodymium-iron-boron magnets give permanent-magnet traction motors their torque density. Schaeffler has developed a process at its Szombathely plant to recover those magnets from defective rotors and reuse them in new ones, drawing on manufacturing scrap rather than vehicles at the end of their lives.

Sumida introduces DC common-mode chokes rated up to 16 A for automotive power electronics

Sumida has introduced the CNFC6D33 and CNFC11D57, a pair of surface-mount DC common-mode chokes that suppress electromagnetic interference (EMI) on DC power lines. The company lists traction inverters, onboard chargers, automotive powertrain systems and automotive HVAC, including electric compressors and PTC heaters, among the applications, alongside industrial and consumer electronics.

The smaller CNFC6D33 measures 7.2 × 6.2 × 3.5 mm. Sumida's product listing rates its versions at 1.5 A and 4 A and gives minimum common-mode impedance at 100 MHz of 500 Ω to 1,970 Ω. Typical impedance reaches 2,500 Ω. DC resistance (DCR) is as low as 15 mΩ maximum.

The CNFC11D57 measures 12.3 × 11.3 × 6.0 mm and comes in three impedance configurations spanning 240 Ω to 1,000 Ω minimum common-mode impedance at 100 MHz. The listing rates its versions at 10 A and 16 A, and DCR is as low as 3 mΩ maximum.

Both parts operate from -40° C to +150° C, including self-heating. Sumida's product announcement also lists an 80 V Hi-Pot test voltage.

A common-mode choke's windings impede noise currents that flow in the same direction on both conductors of a line. The DC supply current flows out on one conductor and back on the other, so its magnetic fields cancel in the core and it sees little more than the windings' DC resistance.

Sumida says both parts are RoHS-listed, have provisional AEC-Q200 compliance and are available through its global distribution network. Custom windings are offered for OEM applications. The company's August product announcement had described the chokes as in pilot production.

"The increasing use of power electronics in vehicles has created new sources of high-frequency electrical noise," said Carl G. LeJambre III, Sumida's Vice President of Sales. "Switching converters, inverters, and onboard chargers can generate unwanted common-mode currents that can interfere with other electronic systems if not adequately controlled."
