2SK3111-Z-E1-AZ-VB Product details
Back to previous pageProduct introduction：
2SK3111-Z-E1-AZ-VB is a Single N-MOS deeply optimized for medium-to-high voltage power switching scenarios. The Trench process balances low switching loss and high reliability, while the TO263 package achieves a balance between heat dissipation capability and ease of installation. The combination of 200V withstand voltage, 40A current carrying capacity, and 48mΩ on-resistance makes it an ideal cost-reducing incremental option for replacing traditional TO220 packaged devices in industrial power supplies, motor drives, and automotive systems, especially suitable for medium-to-high power, high-reliability applications.
