Power Integrations has demonstrated a 2200 V gallium nitride (PowiGaN) technology, aiming to compete with silicon carbide in high-voltage power conversion applications. The development targets infrastructure sectors including AI datacenters, industrial power, and electric vehicle architectures.
The introduction of 2200 V PowiGaN technology signals a shift in the power semiconductor landscape, potentially offering higher switching efficiency and power density for energy-intensive infrastructure. For the streaming ecosystem, this advancement directly affects the underlying hardware efficiency of AI-driven content delivery networks and datacenter operations that manage massive video workloads. If lateral GaN proves reliable at these voltages, it could reduce the total cost of ownership for high-density server environments by improving thermal management and power conversion. Watch for upcoming reliability qualification data and initial pilot deployments in AI datacenter power distribution units to gauge commercial viability against silicon carbide.
Power Integrations has been steadily expanding its PowiGaN portfolio beyond consumer and industrial applications into higher-voltage territory. The company's GaN platform, which uses a lateral device architecture on silicon substrates, has historically targeted the sub-900 V range for chargers, adapters, and appliance power supplies. The move to 2200 V represents a deliberate push into territory where silicon carbide MOSFETs from Infineon, Wolfspeed, and onsemi currently dominate datacenter power distribution units and EV traction inverters. Ericsson launched its AI in RAN commercial software subscription in June 2026, claiming up to 20% higher downlink throughput across more than 15 live deployments, illustrating the kind of AI-driven infrastructure buildout that is intensifying demand for more efficient power conversion at the rack and facility level.
The competitive dynamics between GaN and SiC have intensified as datacenter operators seek to reduce energy losses in power conversion stages. Nokia and AWS announced in June 2026 that Nokia's Autonomous Networks Fabric will run on AWS, with operators achieving automation rates higher than 90 percent and service delivery times of four hours or less, reflecting the broader trend of cloud-hosted network functions that increase power density requirements in hyperscale facilities. Power Integrations' strategy of using lateral GaN on silicon wafers offers a potential cost advantage over SiC, which requires more expensive substrates and has faced supply constraints. However, reliability qualification at 2200 V remains the critical hurdle, as lateral GaN devices have historically faced challenges with dynamic on-resistance and long-term gate oxide stability at elevated voltages.
The technical benchmarking landscape for wide-bandgap semiconductors in datacenter applications has become more granular. Ericsson described its network vision as an intelligent fabric where uplink traffic could triple over the next five years, driven by AI glasses, sensors, and real-time video, underscoring how AI workloads are reshaping power delivery requirements across edge and core infrastructure. For Power Integrations, the 2200 V PowiGaN demonstration must now be validated through JEDEC-standard reliability testing and compared against SiC benchmarks in metrics such as switching loss per cycle, thermal impedance, and mean-time-between-failure under continuous high-voltage stress. The company's track record in shipping billions of GaN devices at lower voltages provides manufacturing credibility, but the transition to kilovolt-class operation will require new packaging approaches and potentially different gate driver architectures to realize the efficiency gains that could challenge SiC's entrenched position in datacenter power supplies.
