APEC 2026: Menlo Micro Brings MEMS-Based Power Switching on the Strength of Navy Program Milestone

Why It Matters

The breakthrough demonstrates a path to ultra‑compact, high‑density power protection that can reduce weight, cost, and thermal complexity for defense, data‑center, and emerging quantum markets.

Key Takeaways

• Menlo completed Navy Task 4, 0.5 MW panel.
• Ideal Switch achieves 2.5 kW per cubic inch density.
• Metal‑to‑metal MEMS eliminates heat sinks.
• Switches ten times faster than mechanical breakers.
• Targets defense, data centers, and quantum computing.

Pulse Analysis

Menlo Micro’s Ideal Switch represents a paradigm shift in power electronics by replacing semiconductor junctions with a metal‑to‑metal MEMS contact. This architecture delivers physical conduction when closed, slashing on‑resistance and virtually eliminating the resistive heating that forces designers to add bulky heat sinks. The result is a compact module—just 60 mm by 60 mm by 11 mm—packing 6 kW of power, or about 2.5 kW per cubic inch, a density that rivals or exceeds many solid‑state solutions while retaining the robustness of a mechanical breaker. For engineers accustomed to managing thermal loads in IGBT or SiC MOSFET systems, the Ideal Switch offers a simpler, lighter alternative that can be integrated into space‑constrained platforms.

The recent Navy milestone adds credibility and a clear path to scale. Task 4 validated a 1,000 V, 500 A panel capable of handling 0.5 MW, built from four modular 1,000 V/125 A units. The modular design is intended to grow toward the program’s 10 MW target, positioning the technology for defense‑grade power distribution, high‑reliability industrial systems, and next‑generation data‑center architectures. Faster fault interruption—ten times quicker than conventional mechanical breakers—means tighter protection for dense rack environments, where a single fault can cascade across high‑performance AI workloads.

Beyond power protection, Menlo’s platform is branching into niche markets such as quantum computing with the MM4250 cryogenic SP6T switch. The same MEMS principles that enable low‑loss, high‑speed switching in power applications also support ultra‑low‑noise RF routing at cryogenic temperatures, a critical need for scalable quantum processors. As AI accelerators and quantum systems demand ever‑greater power density and reliability, Menlo’s technology could become a foundational component, driving adoption across sectors that value speed, efficiency, and minimal thermal footprints.
