FDMC7200-VB Product details
Back to previous pageProduct introduction：
FDMC7200-VB is a Half-Bridge N+N dual N-MOSFET deeply optimized for low-voltage power switching and synchronous rectification applications. Using Trench technology, it achieves a good balance between switching speed, conduction loss, and reliability. The DFN8(3X3)-C package combines a compact footprint with excellent thermal paths, making it suitable for high-density power board designs. The combination of 30V withstand voltage, 35A continuous current capability, and ultra-low 9mΩ on-resistance (@VGS=10V) makes it an ideal power stage choice for high-current applications such as DC-DC converters, motor drives, and battery protection.

VDS=30V: Suitable for 5V/12V/24V systems, providing ample voltage margin for switching spikes and reducing avalanche failure risk.
VGS=±20V: Compatible with 1.8V~12V logic levels, can be driven directly by MCU/PWM controllers, simplifying peripheral circuitry.
Vth=1.7V (typical): Can be effectively turned on with low-voltage drive, meeting the needs of battery-powered and wide voltage input scenarios.
RDS(on)=9mΩ @ VGS=10V / 16mΩ @ VGS=4.5V: Extremely low on-resistance, significantly reducing full-load losses, improving conversion efficiency, and lowering temperature rise.
ID=35A: Ample continuous current capability, suitable for high power density applications, capable of handling transient peak currents such as motor stall or battery short circuit.
Half-Bridge Configuration: Integrates two N-MOSFETs in a DFN8(3X3)-C package, simplifying half-bridge circuit layout, reducing parasitic inductance, and improving high-frequency operational stability.
Trench Technology: Optimizes gate charge and switching characteristics, balancing low switching losses with low EMI risk under high-frequency PWM.
Domain and module applications：
DC-DC Converters: As a synchronous rectifier or half-bridge power stage, the 9mΩ low on-resistance significantly improves heavy-load efficiency, suitable for servers, communication power supplies, and automotive DC-DC converters.
Low-Voltage Motor Drives: Half-bridge integration saves PCB area, low conduction and switching losses make motor operation smoother, and controller heat generation is significantly reduced.
Battery Protection Modules: 35A high current capability and milliohm-level on-resistance reduce self-consumption of the protection board, and fast shutdown response enhances overcurrent/short-circuit protection reliability.
Power Management Units (PMUs): The DFN8(3X3)-C package is suitable for portable devices and miniaturized modules, with 30V withstand voltage compatible with multi-cell lithium batteries and USB-PD applications.
Wireless Charging / Fast Charging Circuits: The half-bridge topology combined with Trench technology supports high-frequency operation, improving power transfer efficiency and reducing temperature rise.
Automotive Auxiliary Power Supplies: Wide gate voltage range and 30V withstand voltage adapt to 12V automotive buses, meeting surge and load dump requirements with high reliability.
Power Tools and Industrial Controls: 35A continuous current and low thermal resistance package can handle high-load continuous output, extending device operating life.
Selection Summary: FDMC7200-VB achieves an excellent balance between on-resistance, current capability, half-bridge integration, and package thermal performance. It is a cost-effective choice for 30V low-voltage, high-current power switching and half-bridge topology applications, especially for projects with strict requirements for efficiency, power density, and heat dissipation.
