NVD4804NT4G-VB Product details
Back to previous pageProduct introduction：
The NVD4804NT4G-VB is a Single N-MOS deeply optimized for low-voltage, high-current power switching scenarios. Its Trench process combines extremely low conduction losses with high switching reliability, and the TO252 package achieves a good balance between thermal dissipation and space usage. The combination of a 30V voltage rating, 85A current capability, and 4mΩ on-resistance makes it an ideal choice for applications such as high-efficiency power conversion, battery protection, and motor drives, particularly suited for medium-to-high power density systems with stringent thermal performance requirements.
