FDW2501N-VB Product details
Back to previous pageProduct introduction：
**FDW2501N-VB is a Dual-N+N channel MOSFET optimized for low-voltage power switching and power management applications. Utilizing Trench technology, it achieves a good balance between low on-resistance and fast switching characteristics. The TSSOP8 package combines miniaturization with reasonable heat dissipation. With a 20V withstand voltage, 7.5A continuous current, and on-resistance as low as 11mΩ, it is a preferred alternative to traditional SOP-8 or DPAK devices in high-density PCB designs, especially suitable for portable devices, DC-DC converters, and battery management applications.**

- **VDS=20V**: Suitable for 5V/12V low-voltage systems, providing sufficient margin for voltage spikes, reducing avalanche breakdown risk, ideal for battery-powered and board-level power rails.
- **VGS=±12V**: Compatible with 2.5V~10V drive logic, can be directly connected to MCU/PMIC or dedicated gate drivers, simplifying peripheral circuit design.
- **Vth=0.86V (Typical)**: Low threshold voltage ensures reliable turn-on under low-voltage drive conditions, supporting stable operation in battery voltage decay scenarios.
- **RDS(on) as low as 11mΩ @ VGS=10V, 12mΩ @ VGS=4.5V, 17mΩ @ VGS=2.5V**: Ultra-low on-resistance covers various drive voltages, minimizing full-load losses and significantly reducing heat generation, helping to shrink the required heat dissipation copper area.
- **ID=7.5A**: Ample continuous current capability to meet the peak current requirements of most low-voltage load switches, synchronous rectification, and motor drives.
- **Package TSSOP8**: Integrated Dual N+N, compact size, low parasitic parameters, supports high-frequency switching, while saving PCB area and assembly costs.
- **Trench Technology**: Optimized cell structure yields a low figure of merit, balancing low conduction losses and switching losses, enhancing overall system efficiency.
