Where will Nexperia's power MOSFETs be manufactured under this deal?

Nexperia's next-generation power MOSFETs will be manufactured at Polar Semiconductor's wafer foundry in Bloomington, Minnesota. Polar operates a fully domestic, high-volume fabrication facility with over six decades of semiconductor manufacturing experience and more than 25 years of automotive production heritage.

What markets does the Polar and Nexperia collaboration target?

The collaboration targets rapidly growing demand across automotive, AI server infrastructure, robotics, and industrial applications. Nexperia's automotive MOSFET portfolio serves xEV powertrain applications including high-voltage traction inverters, onboard chargers, DC-DC converters, and battery management systems.

What is a power MOSFET and why does it matter for electric vehicles?

A power MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a semiconductor switching device used to control and convert electrical power. In electric vehicles, power MOSFETs are used in traction inverters, onboard chargers, DC-DC converters, and battery management systems. Their switching performance, thermal efficiency, and robustness directly affect powertrain efficiency and vehicle reliability.

What is IATF 16949 certification and why is it significant?

IATF 16949 is the international quality management standard for automotive production and relevant service organisations. Polar Semiconductor's IATF 16949 certification means its manufacturing processes meet the rigorous zero-defect quality requirements demanded by automotive OEMs and their supply chains, including for EV powertrain components.

What packaging technologies does Nexperia use for its power MOSFETs?

Nexperia's power MOSFET portfolio uses several advanced packaging technologies. These include copper-clip solutions such as LFPAK and CCPAK, as well as the MLPAK format. These packages are designed to deliver enhanced electrical performance, ruggedness, and thermal efficiency across automotive and industrial applications.

Why is U.S.-based semiconductor manufacturing important for the automotive supply chain?

Domestic U.S. semiconductor manufacturing reduces dependence on geographically concentrated supply sources and provides greater supply chain resilience for automotive OEMs. Polar Semiconductor's fully domestic Minnesota operations offer Nexperia's customers a stable, U.S.-based production source for critical automotive power components.

How does switching performance in power MOSFETs affect xEV powertrain efficiency?

Switching performance in power MOSFETs determines how efficiently the device transitions between on and off states in high-frequency power conversion circuits. Lower switching losses reduce heat generation and improve overall powertrain efficiency in xEV applications such as traction inverters and onboard chargers. Nexperia's MOSFET portfolio is specifically designed to help engineers select the right balance of switching performance and robustness for each application.

What voltage classes does Nexperia's next-generation MOSFET portfolio cover?

Under the Polar Semiconductor collaboration, Nexperia is developing an extensive portfolio of next-generation power MOSFETs spanning a wide range of voltage classes and package types. While specific voltage parameters for the new portfolio have not been disclosed, Nexperia's existing automotive MOSFET range includes devices from 40 V through to high-voltage classes suited to traction inverter and EV charging applications.

How does the MLPAK platform reduce system cost in automotive power electronics?

Nexperia's MLPAK platform is designed to reduce overall system cost in automotive power electronics by lowering component count and board area requirements. Its high avalanche rating reduces the need for free-wheeling diodes or bulky snubbers in switching circuits. The standardised footprint also enables footprint reuse and simplified design-in, reducing engineering time and qualification costs across multiple automotive applications.

Automotive power semiconductor supply chain gets U.S. manufacturing base

Nexperia and Polar Semiconductor have announced a strategic manufacturing collaboration that strengthens the automotive power semiconductor supply chain. Under the agreement, Nexperia’s next-generation power MOSFETs will be produced at Polar’s IATF 16949-certified wafer foundry in Bloomington, Minnesota. The partnership addresses rapidly growing demand across automotive, AI server infrastructure, robotics, and industrial markets – sectors where reliable component supply underpins EV powertrain and industrial electrification applications.

Polar Semiconductor brings more than six decades of semiconductor manufacturing experience to the collaboration, including a 25-plus-year heritage specifically in automotive production. Its Minnesota facility operates as a fully domestic, high-volume wafer fab committed to zero-defect manufacturing standards – a quality baseline that aligns directly with the rigorous demands of xEV powertrain applications, including traction inverters, onboard chargers, and battery management systems.

Nexperia, headquartered in Nijmegen, Netherlands, will develop a broad portfolio of next-generation power MOSFETs under the collaboration, spanning multiple voltage classes and package types. The expanded range is designed to meet diverse power electronics requirements across the automotive and industrial sectors. Nexperia’s existing automotive MOSFET portfolio already serves xEV powertrain applications including high-voltage traction inverters, onboard chargers, DC-DC converters, and battery management systems.

“This collaboration is an important step in strengthening Nexperia’s long-term manufacturing and supply-chain strategy,” said Stefan Tilger, Nexperia’s interim CEO. “By working closely with Polar Semiconductor, we are securing reliable capacity and providing our customers with a strong, stable, and resilient supply foundation to support future growth.”

Power MOSFET portfolio targets EV powertrain supply chain demands

Nexperia has continuously advanced its packaging technologies to improve thermal management and electrical performance in demanding automotive environments. Its copper-clip LFPAK and CCPAK packages, along with the MLPAK format, deliver enhanced electrical performance, ruggedness, and thermal efficiency. The MLPAK platform is specifically designed to reduce overall system cost in automotive power electronics designs by lowering component count and board area, while maintaining the switching performance and robustness that automotive OEMs require.

Fredrik Öberg, General Manager of Business Group MOS at Nexperia, highlighted the shared quality commitment between the two firms. Reza Kazerounian, Executive Chairman of Polar Semiconductor, described the partnership as validation of Polar’s strategy to build a differentiated foundry focused on power, sensor, and high-voltage semiconductors.

Production of the next-generation MOSFET portfolio will advance as Nexperia develops its full voltage-class roadmap for manufacture at Polar’s Minnesota facility, with supply targeted at automotive and industrial customers across AI server infrastructure and electrification markets.
