PowerMakers: How Wolfspeed’s Fayetteville Team Turns Silicon Carbide Expertise into Customer Momentum

When customers partner with the Wolfspeed team in Fayetteville, AR, they’re not just engaging a facility—they’re stepping into a collaborative environment, purpose built to solve complex silicon carbide challenges from materials to modules. What distinguishes the site isn’t any single capability, but how deeply integrated expertise, rapid prototyping, and system‑level thinking come together to accelerate customer success.

From the first engagement, the Fayetteville team takes a full-system approach. Customers enter a technical dialogue that brings multiple subject‑matter experts to the table at once. Materials scientists, packaging engineers and applications specialists all contribute to understanding what the customer is truly trying to achieve—whether that’s higher efficiency, smaller size, lower cost, or faster speed to market.

“We want to understand what levers we can pull,” explains Ty McNutt, Sr. Director Package Development and leader of the Fayetteville team. “Efficiency, speed, size, reliability—those tradeoffs all matter.  And because all that expertise is in the same room having a dialogue and asking questions, we can get to the right answer much faster.”

Seeing the Full System—Not Just the Part

That breadth of perspective, combined with the team’s understanding of a broad range of end applications, often reveals opportunities customers hadn’t considered. In one example, a customer arrived with a clear request: match a competitor’s module at a lower price. Instead of simply responding with a like‑for‑like design, the Fayetteville team took a step back and analyzed the customer’s overall circuit and system constraints.

Packaging and applications experts quickly identified an opportunity to redesign the layout using a different packaging approach—shifting to a PCB‑style configuration that reduced copper usage and eliminated the need for large, heavy bus bars. While the design required more packages, the overall system cost dropped significantly, while performance and efficiency improved.

The result was shifting Wolfspeed from a secondary supplier option to the primary supplier for this large customer, while decreasing overall system cost and increasing system performance. “That’s the difference between building a widget and creating system‑level solution,” McNutt says.

End‑to‑End Expertise, All in One Place

When working with the Wolfspeed team in Fayetteville, customers aren’t navigating handoffs across multiple sites or vendors. Instead, they see the entire lifecycle of a power package in one visit—design, simulation, prototyping, production capability, reliability testing, failure analysis, and end‑of‑line validation all under one roof.

This co‑location enables rapid iteration. Designs begin in advanced simulation, using finite element analysis at both the die and package levels. From there, the team quickly moves into multiple tiers of prototyping, from early low‑power switching demonstrations to rugged, full‑power hardware capable of exercising real mission profiles.

At each stage, simulation and hardware testing inform one another, creating a fast feedback loop that refines reliability, manufacturability, efficiency, and cost. “Simulation plus quick‑turn prototyping is how we drive speed,” McNutt notes. “We can iterate in weeks instead of months.”

Prototyping as a Competitive Advantage

Speed is often the deciding factor for customers evaluating multiple vendors within a limited sampling window. Fayetteville’s ability to deliver high‑power prototypes quickly frequently makes the difference.

On a recent project, McNutt challenged the team to deliver prototypes for an entirely new platform in just two months. They succeeded, and parts were delivered directly into the customer’s sampling cycle. That experience reinforced what the team already knew: when the business opportunity demands speed, Fayetteville can respond.

That same agility has helped startups and established players alike. McNutt points to Wolfspeed’s work with EPC Power as an example—where early prototypes, tested inside the customer’s control board hardware in Fayetteville labs, proved performance feasibility well before a final production module existed. The hands‑on validation built confidence and accelerated commitment.

A Silicon Carbide First Mindset

Another reason Fayetteville moves faster is focus. While much of the industry evolved from silicon into silicon carbide, this team has been dedicated to SiC from the start. That long‑standing specialization has driven the development of advanced metrology, packaging techniques, and system insights that allow engineers to reach answers quickly, especially when customers are on site.

It’s often an eye‑opening experience. Many visitors arrive unaware of the depth of Wolfspeed’s module and packaging expertise—and leave with a new understanding of what’s possible when all those capabilities are tightly integrated.

A Team That’s Invested in Customer Success

Ultimately, what makes the Fayetteville site special is the people. McNutt describes a team that never tires of engaging new challenges—one that is eager to share knowledge, understand unique applications, and help customers move forward with confidence.

“They don’t try to contain their expertise,” he says. “They want to get customers moving. They understand how important it is to translate Wolfspeed’s technology into real‑world success.”

For customers navigating the complexities of silicon carbide adoption, that collaborative, end‑to‑end partnership—delivered with speed—is what turns expertise into impact.
