Microchip Technology has introduced new 3.3 kV HV-D3 mSiC® power modules aimed at accelerating adoption of solid-state transformer (SST) architectures in AI hyperscale data centers and other high-voltage power applications.
The modules integrate 3.3 kV silicon carbide (SiC) MOSFETs and Schottky diodes in an industry-standard 62 mm package, enabling more direct conversion from medium-voltage grid infrastructure to server rack power systems. The launch reflects growing industry interest in reducing power-conversion stages as AI compute clusters continue to push power requirements into multi-megawatt territory.
The HV-D3 modules are built around Microchip’s mSiC technology and incorporate features designed for high-voltage operation, including 6 kV isolation capability, CTI 600-rated materials, extended creepage distances, and a silicon nitride (Si₃N₄) substrate for improved thermal performance and power-cycling reliability. The higher voltage rating enables designers to reduce the number of series-connected devices by roughly half compared with lower-voltage SiC alternatives when interfacing with 13.8 kV and 34.5 kV grid systems.
The product family targets the 100–300 A range, a segment positioned between discrete SiC devices and larger power modules. Available configurations include half-bridge and common-source topologies, with optional anti-parallel Schottky diodes, supporting both hard-switching and soft-switching applications.
Beyond AI infrastructure, the modules address multiple high-power markets including megawatt EV charging systems, medium-voltage motor drives, rail and heavy transportation, and industrial and defense power systems.

Infineon Technologies AG will showcase its broad semiconductor portfolio at PCIM Europe 2026, emphasizing future power infrastructure, AI data centers, robotics, and electromobility. The company’s demonstrations span silicon (Si), silicon carbide (SiC), and gallium nitride (GaN) technologies, reinforced by software, design tools, and cybersecurity capabilities.
A major focus area is future-proof power infrastructure. As AI data centers and electrified industries increase power demand, Infineon is highlighting technologies for battery energy storage systems, uninterruptible power supplies (UPS), solid-state transformers (SSTs), and solid-state circuit breakers (SSCBs). Notably, its CoolSiC™ JFET-based SSCB solutions are designed to provide microsecond-level fault isolation for next-generation DC grids.
For AI data centers, Infineon is presenting a “grid-to-core” approach that covers the complete power delivery chain. Solutions include semiconductor devices, gate drivers, microcontrollers, and sensors supporting high-voltage DC architectures, intermediate bus converters, voltage regulators, battery backup units, and intelligent protection systems. This reflects the industry’s ongoing shift toward HVDC sidecars and DC microgrid architectures required by rapidly increasing AI workloads.
In electromobility, Infineon is showcasing integrated system-level solutions for traction inverters, on-board chargers, DC-DC converters, and battery management systems. Its “One Inverter, One Infineon” concept combines multiple semiconductor technologies to optimize drivetrain efficiency, reduce system complexity, and improve space utilization. Demonstrations also include CoolSiC™, CoolGaN™, EasyPACK™ S modules, CIPOS™ Prime solutions, XENSIV™ sensors, and AURIX™ TC4xx microcontrollers.
The company is also targeting the fast-growing robotics market, demonstrating high-efficiency motor control and power management systems for industrial robots, drones, and emerging humanoid platforms. These solutions leverage CoolGaN power semiconductors, PSOC™ Control C3 microcontrollers, and XENSIV sensors to deliver compact and highly responsive control architectures.
Beyond semiconductor hardware, Infineon is emphasizing security and regulatory readiness through support for the upcoming EU Cyber Resilience Act. The company is positioning secured-by-design semiconductor solutions as a key differentiator for customers facing increasing cybersecurity and compliance requirements.

STMicroelectronics has expanded its STPOWER portfolio with a new family of 700 V gallium nitride (GaN) power transistors designed to improve efficiency and increase power density in medium- and high-power applications.
The new enhancement-mode PowerGaN HEMTs target rapidly growing markets including AI servers, robotics, industrial power supplies, smart-grid infrastructure, and advanced electrification systems. By extending GaN technology into higher power levels, ST aims to address increasing performance demands that are challenging the limits of conventional silicon-based power solutions.
The new portfolio consists of seven devices with current ratings ranging from 6 A to 29 A and typical RDS(on) values between 53 mΩ and 270 mΩ. The devices leverage the inherent advantages of GaN technology, including low conduction losses, extremely low switching losses at high frequencies, low gate charge, and zero reverse recovery characteristics.
These features enable operation at significantly higher switching frequencies, allowing reductions in the size of magnetic components and passive elements while increasing overall power density and lowering system operating temperatures.
From a packaging standpoint, the devices are available in DPAK, TO-LL, and PowerFLAT surface-mount packages. TO-LL and PowerFLAT versions include Kelvin source connections that improve noise immunity, enhance gate-driver performance, and support cleaner switching behavior.
