Overview

Description

The FDB031N08 is an N-channel MOSFET from ON Semiconductor, designed for high-efficiency power applications. Key features include:
- Voltage Rating: 80V
- Current Rating: 110A (pulsed) / 50A (continuous)
- Low On-Resistance (RDS(on)): 3.1 mΩ (max at VGS=10V)
- Fast Switching: Optimized for high-speed operation
- Package: TO-263 (D2PAK), suitable for power management
Commonly used in DC-DC converters, motor drives, and load switches, it offers low conduction losses and robust thermal performance. Ensure proper gate drive (VGS ≥ 10V for full performance) and heatsinking for high-current applications.
For detailed specs, refer to the datasheet.
