2SK4065-DL-1EX-VB Product details
Back to previous pageProduct introduction：
2SK4065-DL-1-EX-VB is a Single N-MOS deeply optimized for high-power-density switching applications, using Trench technology to balance extremely low conduction loss with excellent switching reliability. The TO263 package offers good heat dissipation and current carrying capacity, suitable for medium-to-high-power power conversion and motor drive applications. The combination of 80V withstand voltage, 120A continuous current, and 6mΩ on-resistance makes it an ideal high-efficiency alternative to traditional D²PAK or multi-tube parallel solutions, especially for high-current, high-reliability industrial-grade products.
