Nexperia China launches 19 automotive MOSFETs on 12-inch line

Nexperia China unveiled a 19-product automotive MOSFET portfolio built on a 12-inch mass-production platform, saying the move cuts per-chip costs by up to 50% versus 8-inch wafers. The launch targets EV and automotive power systems, with delivery to major domestic customers set for the second half of 2026.

Why it matters: - The 12-inch platform lowers per-chip cost while boosting output, which can matter for high-volume automotive power electronics. - Nexperia China says the new MOSFETs support body control, infotainment, battery protection, lighting, OBCs, traction inverters and battery management systems. - The portfolio arrives as automakers and suppliers push for higher efficiency, better thermal performance and more local sourcing.

What happened: - Nexperia China released 19 automotive MOSFET products in the 40V to 100V range. - The company said the devices are built on its proprietary 12-inch SGT T2X automotive MOSFET platform. - Mass production is slated for the second half of 2026. - The products have entered supply chains of leading domestic new-energy vehicle customers.

The details: - The T2X platform is designed to reduce on-resistance at the same chip area by optimizing gate structure, doping profile and termination design. - The platform also improves gate charge and gate-drain charge, which lowers both conduction losses and switching losses. - Nexperia China says the 12-inch process can produce about 5.7 times as many effective chips as a 5-inch wafer, about 4 times as many as a 6-inch wafer and about 2.2 to 2.4 times as many as an 8-inch wafer. - The company says that translates to per-chip cost cuts of about 70% versus 5-inch wafers, 60% versus 6-inch wafers and 50% versus 8-inch wafers. - The 40V devices reach on-resistance as low as 0.48 milliohms, more than 50% better than the previous generation. - The 80V platform reaches a minimum on-resistance of 1.3 milliohms, 45% lower than the previous generation. - Nexperia China says device thermal resistance and avalanche energy are about 20% better than the industry benchmark. - The series completed standardized reliability verification for both automotive and industrial grades. - The full lineup exceeds AEC-Q101 requirements. - Core devices in braking, chassis, steering and battery protection are controlled at parts-per-billion failure levels. - The automotive-grade 100V products reach on-resistance as low as 0.99 mΩ and support safe currents above 460 A. - Nexperia China says those 100V parts fit OBCs, traction inverters and BMS applications.

Between the lines: - The move signals a shift from wafer-size talk to system-level manufacturing economics, where higher output and lower cost can be as important as raw electrical performance. - Nexperia China is also framing the launch as a localization milestone, saying some core-device localization has risen from under 20% to nearly 100%. - The company says its development cycle has fallen from 24 to 36 months to 6 to 12 months, which would speed product refreshes if sustained. - Nexperia ranks No. 1 globally in small-signal MOSFETs and among the global top three in automotive power MOSFETs.

What's next: - Nexperia China expects mass-production delivery in the second half of 2026. - The company appears positioned to expand its automotive power MOSFET footprint as more domestic EV programs move into production.

The bottom line: - Nexperia China is using 12-inch manufacturing to pair lower cost with higher-performance automotive MOSFETs, aiming squarely at China’s fast-growing EV supply chain.
