Navitas Semiconductor introduced a new level of reliability to meet the system lifetime requirements of the most demanding automotive and industrial applications. Navitas’ latest generation of 650 V and 1200 V ‘trench-assisted planar’ SiC MOSFETs combined with an optimized, HV-T2PaK top-side cooled package, delivers the industry’s highest creepage of 6.45 mm to meet IEC-compliance for applications up to 1200V.
Navitas’ HV-T2PaK SiC MOSFETs significantly increase system-level power density and efficiency while improving thermal management and simplifying board-level design and manufacturability. Target applications include EV on-board chargers (OBC) & DC-DC converters, data-center power supplies, residential solar inverters & energy storage systems (ESS), EV DC fast chargers, and HVAC motor drives.
AEC-Q101 is an automotive industry standard developed by the Automotive Electronics Council (AEC) to establish common part-qualification and quality-system standards. Navitas has created an industry-first benchmark, ‘AEC-Plus’*, indicating parts qualified above and beyond the existing AEC-Q101 and JEDEC product qualification standards. This new benchmark showcases Navitas’ deep understanding of system-level lifetime requirements and a strong commitment to enabling rigorously designed and validated products for demanding mission profiles in automotive and industrial applications.
The ‘AEC-Plus’ qualification standards extend further into rigorous multi-lot testing and qualification. Key additions to the existing AEC-Q101 requirements include:
- Dynamic reverse bias (D-HTRB) & dynamic gate switching (D-HTGB) to represent stringent application mission profiles
- Over 2x longer power & temperature cycling
- Over 3x longer duration for static high-temperature, high-voltage tests (e.g. HTRB, HTGB).
- 200°C TJMAX qualification for overload operation capability
Navitas’ HV-T2PaK top-side cooled package, in an industry-standard compact form factor (14 mm x 18.5 mm), is optimized with an innovative groove design in the package mold compound that extends the creepage to 6.45 mm without reducing the size of the exposed thermal pad and ensuring optimal heat dissipation. In addition, the exposed thermal pad has a nickel, nickel-phosphorus (NiNiP) plating, as opposed to tin (Sn) plating from existing TSC package solutions, which is critical to preserving the post-reflow surface planarity of the exposed pad and ensuring thermally efficient and reliable attachment to the thermal interface material (TIM).
Enabled by over 20 years of SiC technology innovation leadership, Navitas’ GeneSiC™ ‘trench-assisted planar SiC MOSFET technology’ offers up to 20% lower on-resistance under in-circuit operation at high temperatures compared to competition and superior switching figure-of-merits which result in the lowest power losses across a wider operating range. All GeneSiC™ SiC MOSFETs have the highest-published 100%-tested avalanche capability, excellent short-circuit withstand energy, and tight threshold voltage distributions for easy paralleling.
The initial HV-T2PaK portfolio includes 1200 V SiC MOSFETs with on-resistance ratings ranging from 18 mΩ to 135 mΩ and 650 V SiC MOSFETs with on-resistance ratings ranging from 20 mΩ to 55 mΩ. Lower on-resistance (<15 mΩ) SiC MOSFETs in HV-T2PaK package will be announced later in 2025.

Nexperia announced a range of highly efficient and robust automotive qualified silicon carbide (SiC) MOSFETs with RDS(on) values of 30, 40 and 60 mΩ. These devices (NSF030120D7A0-Q, NSF040120D7A1-Q, NSF060120D7A0-Q), which deliver industry-leading figures-of-merit (FoM), were previously offered in industrial grade and have now been awarded AEC-Q101 certification.
This makes them suitable for automotive applications like onboard chargers (OBC) and traction inverters in electric vehicles (EV) as well as for DC-DC converters, heating ventilation and air-conditioning systems (HVAC). These switches are housed in the increasingly popular surface mounted D2PAK-7 package which is more suitable for automated assembly operations than through-hole devices.
RDS(on) is a critical performance parameter for SiC MOSFETs as it impacts conduction losses. However, concentrating on the nominal value, neglects the fact that it can increase by more than 100% as device operating temperatures rise, resulting in considerable rise of conduction losses. The temperature stability is even more critical when SMD package technologies are used compared to through-hole technology since devices are cooled through the PCB.
Nexperia identified this as a limiting factor in the performance of many currently available SiC devices and leveraged the features of its innovative process technology to ensure that its new SiC MOSFETs offer industry-leading temperature stability, with the nominal value of RDS(on) increasing by only 38% over an operating temperature range from 25 °C to 175 °C. This feature enables customers to address higher output power in their applications achieved with a higher nominal 25°C rated RDS(on) from Nexperia compared to other vendors without sacrificing performance.
“This feature allows to get more power out of the selected Nexperia SiC MOSFET devices compared to similarly rated RDS(on) devices from other vendors, delivering a clear cost advantage for customers on semiconductor level. Additionally, relaxed cooling requirements, more compact passive components, and higher achievable efficiency allow customers more degrees of freedom in their design and lower total cost of ownership. We’re especially excited that these products are now available for the automotive market, where their performance and efficiency benefits can make a real difference in next-generation vehicle designs”, says Edoardo Merli, SVP and Head of Business Group Wide Bandgap, IGBT & Modules (WIM).
Nexperia is planning to release automotive-qualified versions of its 17 mΩ and 80 mΩ RDS(on) SiC MOSFETs in 2025.

WeEn Semiconductors showcased its silicon carbide (SiC) MOSFETs and Schottky Barrier Diodes (SBDs) in highly thermally efficient TSPAK packages at this year’s PCIM Expo conference and trade fair. The new packages enable engineers to improve efficiency, reduce form factors, extend reliability and lower EMI across a variety of high-power applications.
Providing effective heat dissipation from a thermal pad on the surface of the SiC device rather than via a PCB substrate, the company’s top-side cooling TSPAK technologies can reduce J-A (junction-to-ambient) thermal resistance by up to 16% compared to conventional devices. As a result, the packages help to simplify thermal management design, lower losses and increase power density.
By minimizing or eliminating the need for complex PCB cooling, TSPAK devices reduce component count and drive down system costs. In addition, the ability to support a greater number of power cycle extends reliability, while reduced EMI helps engineers to simplify system EMC compliance. EMI reduction derives from the fact that the circulating current that creates the magnetic field is no longer blocked by the thermal vias necessary in conventional bottom-side cooling designs and can return to the source directly, minimizing magnetic interference.
WeEn’s TSPAK SiC technologies are ideally suited to on-board chargers and high-voltage-to-low-voltage DC-DC converters in electric vehicles (EVs), automotive HVAC compressors, vehicle charging stations, photovoltaic (PV) renewable energy systems and power supplies for computing and telecom servers. TSPAK MOSFETs offer voltage ratings from 650 V to 1700 V and on resistance (RDS(ON)) ratings from 20 to 150mΩ. TSPAK SBDs are available with voltages from 650 V to 1200 V and current ratings of 10 A to 40 A.
All products are available in industrial grade and automotive grade variants.
