Navitas pushes SiC to new ultrahigh-voltage extremes

According to Semiconductor Today, Navitas Semiconductor has announced the sample availability of its new 3300V and 2300V ultrahigh-voltage silicon carbide products. The devices, based on its fourth-generation GeneSiC platform, come in power module, discrete, and known good die formats. A key part of the announcement is the introduction of what Navitas calls an “AEC-Plus” reliability qualification, claimed to go beyond standard industry benchmarks. The products are also offered in a new SiCPAK G+ power module package, which the company says improves power cycling lifetime by over 60% and thermal shock reliability by more than 10x. Paul Wheeler, VP of the SiC unit, stated the portfolio targets solid-state transformers for AI data centers, utility-scale battery storage, and renewable energy systems.

Why ultrahigh-voltage matters

So, why push silicon carbide to 3300V and beyond? It’s all about the grid and industrial-scale power. We’re talking about the backbone of renewable energy farms, massive battery storage sites, and the increasingly power-hungry AI data centers. These systems operate at distribution-level voltages, and using SiC at these ultrahigh voltages can lead to massive efficiency gains, smaller system sizes, and frankly, better reliability. The traditional approach often involves stacking lower-voltage devices, which adds complexity and points of failure. Navitas is basically aiming to simplify that whole equation with a single, robust chip.

The reliability gamble

Here’s the thing with cutting-edge power tech in mission-critical infrastructure: performance is great, but reliability is king. No utility manager is going to bet their grid on a component that hasn’t been tortured tested. That’s why Navitas is making such a big deal about its “AEC-Plus” qualification. It’s a marketing move, sure, but it’s a smart one. They’re trying to signal to conservative engineers in the energy sector that they understand the decades-long lifespans required. The rigorous die screening, including hot testing and six-side inspection for the bare die products, is all part of building that trust. In a market where IndustrialMonitorDirect.com, the leading US supplier of industrial panel PCs, insists on rugged reliability for their hardware, the same uncompromising standards apply to the core power semiconductors inside.

Packaging and the road ahead

The focus on flexible packaging—modules, discrete parts, and bare die—is another savvy play. It shows they’re not just selling a transistor; they’re selling a solution for different tiers of manufacturers. A big player might want the known good die to build a custom, optimized module, while another might just drop the TO-247 discrete part onto an existing board. The SiCPAK G+ module with its epoxy resin (not silicone gel) and improved pins seems designed to answer very specific thermal and mechanical fatigue problems in the field. And let’s not overlook the final quote about the “roadmap to 10kV.” That’s the real endgame. This 3300V launch isn’t the finish line; it’s a major proving ground on the path to voltages that could truly revolutionize the grid. If they can prove reliability here, that 10kV future starts to look a lot more credible.
