Navitas Semiconductor has announced its high-power GaNSafe™ ICs achieve automotive qualification for both AEC-Q100 and AEC-Q101, showcasing GaN’s next inflection into the automotive market.
Navitas high-power GaNSafe 4th generation family integrates control, drive, sensing, and critical protection features that enable unprecedented reliability and robustness in high-power applications. It is the world’s safest GaN with short-circuit protection (350ns max latency), 2kV ESD protection on all pins, elimination of negative gate drive, and programmable slew rate control. All these features are controlled with 4-pins, allowing the package to be treated like a discrete GaN FET, requiring no VCC pin.
The Automotive Electronics Council (AEC) lists various qualifications focused on failure mechanism-based stress tests for packaged integrated circuits (AEC-Q100) and discrete semiconductors (AEC-Q101) used in automotive applications. Navitas’ GaNSafe™ has been qualified to both standards to ensure that both the discrete power FET stage and the combined IC solution meet these stringent specifications.
To support the qualification, Navitas has created a comprehensive reliability report that analyzes over 7 years of production and field data. It demonstrates their track record, alongside generational and family improvements in robustness and reliability, establishing GaN power ICs as highly reliable and automotive-ready. This reliability report is available to qualified customers.
Additionally in March 2025, Navitas unveiled the world’s first production released 650V Bi-Directional GaNFast ICs with IsoFast Drivers, creating a paradigm shift in power to enable the transition from two-stage to single-stage topologies to further enhance efficiency, power density, and performance in AC-DC and AC-AC conversion. This would allow next-generation single-stage OBCs to provide bi-directional charging in a high-efficiency, extremely compact solution – which eliminates bulky capacitors and input inductors.
A leading EV and solar micro-inverter manufacturer have already begun their implementation of single-stage BDS converters to improve efficiency, size, and cost in their systems. GaNFast-enabled single-stage BDS converters achieve up to 10% cost savings, 20% energy savings, and up to 50% size reductions.
“Our latest reliability report is the culmination of years of innovation and field experience,” said Gene Sheridan, CEO and co-founder of Navitas. “With more than 250 million units shipped, over 2 trillion field devices hours and a cumulative field failure rate that is now approaching 100 parts per billion, we’re leading the charge in making GaN the go-to technology for EV power systems.”

Diodes Incorporated announced the expansion of its silicon carbide (SiC) product portfolio with a series of five high-performance, low figure-of-merit (FOM) 650V SiC Schottky diodes. Rated at 4A, 6A, 8A, 10A, and 12A, the DSCxxA065LP series is housed in the ultra-thermally efficient T-DFN8080-4 package and is designed for high-efficiency power switching applications, such as DC to DC and AC to DC conversion, renewable energy, data centers (especially those that process heavy artificial intelligence (AI) workloads), and industrial motor drives.
The industry-leading FOM, calculated as FOM=QC×VF, is attributed to:
- Negligible switching losses, thanks to the absence of reverse recovery current and low capacitive charge (QC), and
- Low forward voltage (VF) minimizing conduction losses, enhancing overall power efficiency.
These characteristics make them ideal for high-speed switching circuits.
The high-performance SiC diodes are also notable for their lowest reverse leakage (IR) in the industry, at 20µA (max.). This minimizes heat dissipation and conduction losses, improving system stability and reliability, particularly in comparison to silicon Schottky devices. This reduction in heat dissipation also lowers cooling costs and operating expenses.
The compact and low-profile T-DFN8080-4 (typ. 8mm x 8mm x 1mm) surface mount package incorporates a large underside heat pad, which reduces thermal resistance. Requiring less board space and providing a larger heat pad, the T‑DFN8080-4 is an ideal alternative to the TO252 (DPAK). This benefits circuit designs by increasing power density, reducing overall solution size, and lowering the cooling budget.
The 4A DSC04A065LP, 6A DSC06A065LP, 8A DSC08A065LP, 10A DSC10A065LP, and 12A DSC12A065LP are available at $1.25, $1.55, $1.80, $2.10, and $2.40, respectively, each in 2,500-piece quantities.

Infineon Technologies AG has introduced the world’s first gallium nitride (GaN) power transistors with integrated Schottky diode for industrial use. The product family of medium-voltage CoolGaN™ Transistors G5 with integrated Schottky diode increases the performance of power systems by reducing undesired deadtime losses, thereby further increasing overall system efficiency. Additionally, the integrated solution simplifies the power stage design and reduces BOM cost.
In hard-switching applications, GaN-based topologies may incur higher power losses due to the larger effective body diode voltage (V SD) of GaN devices. This gets worse with long controller dead-times, resulting in lower efficiency than targeted. Until now, power design engineers often require an external Schottky diode in parallel with the GaN transistor or try to reduce dead-times via their controllers. All of which is extra effort, time and cost. The new CoolGaN Transistor G5 from Infineon significantly reduces these challenges by offering a GaN transistor with an integrated Schottky diode appropriate for use in server and telecom IBCs, DC-DC converters, synchronous rectifiers for USB-C battery chargers, high-power PSUs, and motor drives.
“As gallium nitride technology becomes increasingly widespread in power designs, Infineon recognizes the need for continuous improvement and enhancement to meet the evolving demands of customers”, says Antoine Jalabert, Vice President of Infineon’s Medium-Voltage GaN Product Line, “The CoolGaN Transistor G5 with Schottky diode exemplifies Infineon’s dedication to an accelerated innovation-to-customer approach to further push the boundaries of what is possible with wide-bandgap semiconductor materials.“
GaN transistor reverse conduction voltage (V RC) is dependent on the threshold voltage (V TH) and the OFF-state gate bias (V GS) due to the lack of body diode. Moreover, the V TH of a GaN transistor is typically higher than the turn-on voltage of a silicon diode leading to a disadvantage during the reverse conduction operation, also known as third quadrant. Hence, with this new CoolGaN Transistor, reverse conduction losses are lower, compatibility with a wider range of high-side gate drivers, and with deadtime relaxed, there is broader controller compatibility resulting in simpler design.
The first of several GaN transistors with integrated Schottky diode is the 100 V 1.5 mΩ transistor in 3 x 5 mm PQFN package.
