- Data centers and AI are driving massive increases in electricity demand, spotlighting the need for more efficient power solutions.
- Navitas Semiconductor’s power chips use gallium nitride (GaN) and silicon carbide (SiC), which outperform traditional silicon in efficiency, heat management, and speed.
- A new partnership with Nvidia aims to use Navitas’s GaN and SiC chips in advanced AI server infrastructure, potentially debuting in 2027.
- Despite innovative technology, Navitas faces significant challenges—including shrinking revenues and high production costs—casting uncertainty on short-term profits.
- Long-term growth may come as GaN/SiC chips become essential for electrification, AI, and fast charging in everything from Tesla vehicles to cloud computing.
The hum of data centers runs our digital world, but their appetite for electricity is growing voracious as artificial intelligence takes the stage. On an otherwise ordinary Wednesday, Wall Street jolted awake when Navitas Semiconductor defied all expectations, its shares leapfrogging as much as 164% before noon. At the heart of this surge? A surprising partnership with Nvidia, the undisputed titan of AI chips.
Beneath the headlines, the story is one of bold thinking and rare materials. While most semiconductors rest on the familiar sands of silicon, engineers at Navitas have mined deeper into the periodic table. Their chips are forged from gallium nitride (GaN) and silicon carbide (SiC), crystalline structures that promise to electrify the future. These substances, harder to craft and pricier to produce than silicon, boast an uncanny ability to handle higher voltages and dissipate heat more efficiently.
Imagine a smartphone charging in under half the usual time, or data center servers packing more computing power into small, energy-sipping enclosures. That’s what GaN and SiC chips can do. Navitas’s chips can convert electricity from grid to device with fewer steps, shrinking energy losses that—on the scale of global cloud computing—add up to a staggering drain.
Nvidia, with its eye on the exponential demands of artificial intelligence, is betting that Navitas’s miniaturized, high-efficiency power chips will supercharge its next-generation server infrastructure, codenamed Rubin Ultra. These servers are scheduled to debut in mid-2027, and if successful, could redefine how energy courses through the world’s digital veins.
Yet, for all the optimism, the narrative isn’t without shadows. Navitas has, until now, wrestled with declining revenues—down nearly 40% in the last quarter—and remains deeply unprofitable, burning through capital with an adjusted operating margin of -84%. With only $74 million in annual revenue, the company’s size belies its ambitions.
Skeptics point out that the leap from promise to profit will be neither easy nor immediate. GaN and SiC chips cost more to make, and until now, their advantages hadn’t fully justified their premium over silicon in most mass-market applications. But as demand for electrification, AI, and rapid charging surges—across everything from fast-charging Tesla vehicles to cloud supercomputers—the tide may be turning.
Financial analysts forecast a slow-burn transformation for Navitas. Major revenue boosts may not surface until 2026 or later, when existing design contracts—reportedly worth nearly half a billion dollars—translate into mass production and sales. Until then, volatility looms: after such a dramatic run-up, a cool-off is likely as the market digests what, for now, is still potential not yet realized.
The message is clear: As AI and electrification reshape everything from smartphones to data centers, the hidden battleground is in how efficiently we move electrons, not just bits and bytes. Navitas, with its bet on radical materials and bold partnerships, just might be building the next backbone of the digital world—but investors and observers would do well to remember that every revolution demands time, courage, and, sometimes, nerves of steel.
Key takeaway: The future of advanced computing may hinge not only on smarter processors but on breakthrough power chips—showcasing how innovation at seemingly minor levels can set off seismic shifts across industries.
This “Unstoppable” Power Chip Could Change AI Forever—But at What Cost?

1. What Makes GaN and SiC Semiconductors So Disruptive?
Gallium Nitride (GaN) and Silicon Carbide (SiC) are semiconductor materials that differ fundamentally from traditional silicon:
– Higher Efficiency: GaN and SiC switches operate at higher voltages and frequencies with less wasted energy. Their superior heat dissipation slashes cooling costs—a radical value-add for hyperscale data centers.
– Faster Switching: They can operate at speeds silicon can’t match, enabling faster charging in consumer electronics and more compact, lightweight designs.
– Durability: SiC, especially, is chemically robust and highly heat-resistant—perfect for electric vehicles (like those from Tesla) and industrial-grade AI server racks.
Specifications (2024)
| Material | Max Bandgap (eV) | Max Operating Temp (°C) | Switching Speed | Relative Cost |
|—————-|——————|————————-|—————–|————–|
| Silicon (Si) | 1.1 | ~150 | Low | $ |
| Gallium Nitride (GaN) | 3.4 | ~200 | Very High | $$ |
| Silicon Carbide (SiC) | 3.3 | >300 | High | $$$ |

2. Why Is This Critical Now? (Industry Trends & Market Forecasts)
– Explosive Data Center Growth: AI training models (e.g., GPT-4, Stable Diffusion) require 3–5x more power per server than pre-AI era infrastructures.
– Sustainability Pressures: According to the International Energy Agency (IEA), global data center electricity use could double by 2026 to over 1,000 TWh/year—a colossal carbon footprint unless efficiency is radically improved.
– Rapid Electrification: Beyond data centers, EVs, renewable energy grids, and ultra-fast charging systems are all racing toward higher-efficiency, rugged power electronics that only GaN and SiC can deliver.
Market Trends:
– The gallium nitride power semiconductor market is projected to grow at a CAGR of over 20% by 2029 (Source: MarketsandMarkets).
– Major chipmakers (Infineon, STMicroelectronics, Texas Instruments) are rapidly expanding GaN and SiC portfolios.

3. Real-World Use Cases & Compatibility
How-To: How GaN/SiC Can Transform Common Devices
– Data Centers: Use GaN/SiC to halve the cooling infrastructure, reduce rack size, and dramatically increase server density.
– Smartphones/Tablets: Enable ultra-fast charging (30 minutes to full from 0–100%), with smaller, lighter chargers.
– EVs: Support higher battery voltages (>800V), boost driving range, and speed up charging times at public stations.
– Solar & Renewables: Cut inverter losses, meaning more household or solar farm power gets used—not wasted as heat.
Tutorial Insight:
Switching to GaN/SiC hardware in power conversion often requires updating supporting circuitry and firmware, but most modern server architectures (from Nvidia and others) are now actively designed to be “material agnostic,” easing the transition.

4. Limitations, Controversies, and Challenges
Key Cons
– Price Premium: GaN and SiC remain up to 5x more expensive per wafer vs. silicon. Mass market adoption has lagged except in high-margin niches.
– Manufacturing Complexity: Both materials are hard to produce at scale. SiC wafers are prone to crystal defects; GaN demands tight process control.
– Profitability Concerns: Navitas’s current revenue and burn rate warrant caution—its high R&D and capital expenses can outpace near-term gains.
Controversy
– Some experts warn that the AI “power crisis” could encourage infrastructural corners to be cut—or worse, that ultra-efficient chips may paradoxically spur even greater demand and total energy use (the so-called “Jevons paradox”).

5. Pressing FAQs
Will Nvidia use GaN/SiC chips in all its new servers?
Only select “Rubin Ultra” high-performance AI clusters are confirmed so far, focusing on workloads where energy efficiency and cooling are rate-limiters.
Are GaN and SiC sustainable?
Relative to silicon, GaN and SiC enable massive net energy and CO₂ savings at scale, but mining/growth of gallium and silicon carbide is energy-intensive; recycling streams are still emerging.
Is Navitas a takeover target?
Given its small size and strategic IP, analysts believe large chipmakers or hyperscalers could eventually acquire it—especially if it secures multi-year, multi-billion-dollar supply contracts.
When will I see GaN/SiC in my everyday devices?
Fast-charging USB adapters already use GaN; SiC is coming to mid-range EVs from 2025 onward. Expect premium laptops and mobile devices to advertise GaN/SiC-based charging or power management by 2026–2027.
How can I invest or get involved?
Consider ETFs or funds focused on advanced semiconductors and electrification plays—direct exposure to single firms like Navitas carries significant volatility.
