Ultra-Low 55mΩ RDS(on) and Robust Thermal Performance in DFN5060

MCC is proud to announce the launch of the MCAC055N20YH, a cutting-edge 200V N-Channel Power MOSFET that redefines what’s possible in compact, high-efficiency power systems. As industries push toward higher power density, smaller footprints, and greater energy efficiency, MCC delivers a solution that meets these demands head-on. 

The MCAC055N20YH combines robust high-voltage capability with exceptional thermal performance and ultra-low conduction losses, all packed into a space-saving DFN5060 package. Leveraging advanced Split-Gate Trench technology, this MOSFET offers designers the perfect balance of speed, efficiency, and reliability for demanding applications such as data center power supplies, telecom infrastructure, industrial automation, renewable energy systems, and professional audio equipment. 

With a 200V VDS rating, 34A continuous current capability, and a low Rds(on) of just 55mΩ, the MCAC055N20YH provides generous design margin for voltage transients while minimizing heat generation and energy loss. Its 0.9°C/W junction-to-case thermal resistance ensures stable operation under heavy loads, enabling cooler, more efficient systems that last longer. 

Features & Benefits:
  • 200V N-Channel Power MOSFET for high-voltage industrial and telecom applications
  • Advanced Split-Gate Trench MOSFET technology optimized for low on-resistance and high switching speed
  • Low Rds(on) of 0.055Ω (max) at Vgs = 10V to minimize conduction losses and heat generation
  • Excellent thermal performance with 0.9°C/W junction-to-case thermal resistance for efficient heat transfer and stable high-power operation
  • Compact DFN5060 package with a 5 mm × 6 mm footprint, delivering high power density in space-constrained designs
  • 200V drain-source voltage (VDS) rating provides ample margin for voltage spikes and ringing in demanding 48–100V systems
