onsemi has introduced its EliteSiC MOSFETs in the industry-standard T2PAK top-cool package, offering improved thermal performance and design flexibility for high-power, high-voltage applications. Targeting sectors such as electric vehicles (EVs), solar energy infrastructure, and energy storage systems, the new solution addresses the growing demand for efficiency and compactness in power electronics.

The newly released 650V and 950V EliteSiC MOSFETs combine onsemi’s advanced silicon carbide technology with the thermally optimized T2PAK top-cool package, providing designers with a powerful tool for tackling thermal challenges in automotive and industrial systems. Initial devices are already shipping to lead customers, with additional variants scheduled for release beginning in Q4 2025.

The EliteSiC T2PAK package enables direct thermal transfer from the MOSFET to the system heatsink, bypassing limitations of PCB-based cooling. This configuration supports superior heat dissipation and lower junction temperatures, resulting in:

  • Reduced thermal resistance and improved thermal efficiency
  • Lower component stress and extended system reliability
  • Higher power density in smaller footprints
  • Simplified thermal design for faster product development cycles

Technical Highlights of the T2PAK Top-Cool Package:

  • Supports RDS(on) values ranging from 12 mΩ to 60 mΩ
  • Minimizes stray inductance for improved switching speeds and reduced energy losses
  • Combines thermal and switching performance advantages of TO-247 and D2PAK formats
  • Offers direct die-to-heatsink contact, eliminating PCB thermal bottlenecks

This packaging innovation allows engineers to design more compact and thermally optimized systems, helping to meet the efficiency requirements of modern power applications in EV powertrains, solar inverters, industrial drives, and high-performance chargers.

With the integration of EliteSiC technology and the top-cool T2PAK format, onsemi continues to expand its capabilities in delivering advanced silicon carbide solutions for next-generation power electronics.
