FDU8796-VB Product details
Back to previous pageProduct introduction：
The VBsemi FDU8796-VB is a Single N-Channel Field Effect Transistor manufactured using Trench technology, specifically designed for low-voltage high-current power conversion and high-power-density control scenarios. Its TO251 package offers excellent heat dissipation capability and installation reliability, suitable for high-stress working environments like power adapters, motor drives, and battery management systems. The device provides extremely low on-resistance and a high drain current capability of up to 100A within a 30V drain-source voltage range, significantly reducing conduction losses and improving overall system efficiency. The gate drive supports 4.5V logic levels, facilitating direct interfacing with common PWM controllers or MCUs.
