Recent NVTS news often triggered large moves: partnerships and ecosystem wins saw strong gains, while conference-related and showcase news produced mixed or negative reactions.
Over the last month, Navitas reported several milestones, including an NVIDIA MGX AI ecosystem collaboration on Jun 3, 2026 that coincided with a 19.26% gain, and a GaN technology launch with Cyient that saw a 24.45% move. Conference participation headlines on May 7 and May 21 and a PCIM showcase preview on May 18 drew smaller, sometimes negative reactions. Today’s SiC packaging news fits the ongoing push into AI, grid, and power infrastructure solutions.
Regulatory & Risk Context
An effective Form S-3ASR shelf with an at-the-market program allows Navitas to sell up to $500,000,000 of Class A Common Stock through designated agents with commissions up to 3.0% of gross proceeds; shelf usage was 0 before this news.
Market Pulse Summary
This announcement expands Navitas’s GeneSiC SiC portfolio with a high-isolation UHV-TO-247-4-ISO package aimed at grid, energy storage, and AI data center applications, building on earlier AI and power-infrastructure initiatives in May–June 2026. The design’s >6000 V isolation, reduced thermal resistance, and higher power dissipation are key technical points to monitor, alongside capital-raising flexibility from the new $500,000,000 at-the-market shelf program.

- Direct-cooled thermal management offered by a reflow-compatible, isolated thermal pad significantly improves power density, reliability, and efficiency.
- Integrated aluminum nitride substrate-based isolation reduces electromagnetic coupling, allowing higher switching speeds and lower EMI management costs.
- Developed for 3300V, 2300V, and 1200V SiC MOSFET products.
TORRANCE, Calif., June 08, 2026 (GLOBE NEWSWIRE) -- Navitas Semiconductor (Nasdaq: NVTS), an industry leader in next-generation GaNFast™ gallium nitride (GaN) and GeneSiC™ silicon carbide (SiC) power semiconductors, today announced the launch of its new UHV-TO-247-4-ISO package, setting a new benchmark for high-performance discrete power devices.
Featuring over 12 mm pin-to-pin creepage and greater than 6000 V integrated isolation, the package is purpose-built for 1200 V to 3300 V GeneSiC SiC MOSFETs, delivering module-like performance in a compact discrete form factor. When compared with standard non-isolated through-hole packages, this package not only eliminates the need for external high-voltage isolation but also improves thermal and EMI performance. This expands Navitas’ packaging portfolio, including SiCPAK® power modules, QDPAK, TO-247-LP, and other high-performance solutions, for more efficient, denser, scalable power systems in energy, grid, and AI data centers.
System Benefits:
- Integrated High-Voltage Isolation: By integrating an Aluminum Nitride (AlN) substrate, this package offers robust high-voltage isolation exceeding 6000 V — eliminating the need for external isolation materials and simplifying system design.
- Direct-Cooled, Reflow-Compatible Thermal Management: A high-voltage isolated, reflow-compatible thermal pad lets the package mount directly to liquid- or air-cooled heat sinks, eliminating external TIM. This reduces RTH,J-HS by up to
60% , leading to up to150% increased power dissipation capability, improving power density, reliability, manufacturability, and overall system cost. - Reduced Coupling Capacitance & Radiated EMI: Integrated high-voltage isolation reduces die-to-heatsink stray capacitance compared to external ceramic-based isolators, effectively minimizing common-mode noise and radiated EMI. This enables higher switching speeds and delivers improved power density, increased system efficiency, and reduced system-level costs associated with EMI mitigation.
- Superior Power and Thermal Cycling Lifetime: Built on a high-performance AlN substrate with active metal brazing (AMB) technology and a robust reflow-compatible heatsink interface, this package eliminates the need for external TIM and isolation materials from the system stack - delivering superior power cycling capability and enhanced thermal cycling lifetime.
- Industry-Standard Form-Factor and Footprint: Compatible with the established high-voltage TO-247-4 form factor and lead geometry, this package allows effortless system integration with no redesign — while delivering superior performance, increased reliability, and lower total system cost.
“High-power system design is fundamentally challenged by the need to balance efficient thermal management with robust high-voltage isolation,” said Paul Wheeler, VP & GM of the SiC Business Unit at Navitas. “The UHV-TO-247-4-ISO package overcomes critical thermal and isolation challenges, delivering power module–class performance in a compact discrete form factor. As a highly efficient building block, it empowers system designers to unlock the full potential of GeneSiC TAP SiC MOSFET technology in next-generation applications such as immersion-cooled and liquid-cooled power electronics.”
Product Portfolio:
The UHV-TO-247-4-ISO package is offered in 3300V, 2300V, and 1200V SiC MOSFET ratings. This packaging breakthrough enables performance improvements in high-voltage grid-tied power conversion systems (PCS), solid-state transformers (SST), battery energy storage systems (BESS), and renewable energy applications.
