HUF75332S3ST-VB Product details
Back to previous pageProduct introduction：
The HUF75332S3ST-VB is a Single N-MOS optimized for low-voltage, high-current power switching scenarios. Its Trench technology balances low conduction losses with high switching reliability, and the TO263 (DPAK compatible) package achieves a good balance between heat dissipation and soldering process. The combination of 60V withstand voltage, 75A continuous current carrying capability, and an ultra-low on-resistance of 11mΩ makes it an ideal cost-effective alternative to traditional DPAK or D2PAK packaged devices, especially suitable for high-power applications such as power conversion, motor drives, and automotive systems.
