2SK3377-Z-E2-AZ-VB Product details
Back to previous pageProduct introduction：
2SK3377-Z-E2-AZ-VB is a Single N-MOS deeply optimized for low-voltage power switch and power management scenarios. Using Trench technology, it balances low conduction losses with high switching speed. The TO252 (DPAK) package achieves a good balance between heat dissipation capability and mounting convenience. The combination of 60V withstand voltage, 45A continuous current capability, and 25mΩ on-resistance makes it an ideal choice for high-reliability power paths in 12V/24V/36V systems, especially suitable for applications with high requirements for temperature rise and current margin, such as motor drives, power conversion, and battery protection.
