FDMS3660S

The FDMS3660S is a dual N-channel PowerTrench MOSFET from ON Semiconductor, designed for high-efficiency power conversion in applications like DC-DC converters, VRMs (Voltage Regulator Modules), and synchronous rectification.
### Key Features:
- Low On-Resistance (RDS(on)): 3.6 mΩ (max) at VGS = 10 V, reducing conduction losses.
- High Current Handling: Up to 60 A continuous drain current.
- Optimized for High-Frequency Switching: Low gate charge (Qg) and output capacitance (Coss) for improved efficiency.
- Compact Power56 Package: Enhances thermal performance and PCB space utilization.
- Wide Voltage Range: Supports 30 V drain-source voltage (VDS).
### Applications:
- Server/GPU power supplies
- POL (Point-of-Load) converters
- Motor drives & battery management
The FDMS3660S is ideal for high-current, high-efficiency designs requiring minimal power loss and compact form factors.
