FDD6680A-VB Product details
Back to previous pageProduct introduction：
FDD6680A-VB is a Single N-MOS deeply optimized for low-voltage, high-current power switching scenarios. Trench technology balances ultra-low on-resistance with high switching speed, and the TO252 (DPAK) package achieves an ideal balance between heat dissipation capability and assembly convenience. The combination of 30V withstand voltage, 70A current-carrying capacity, and 7mΩ on-resistance makes it a preferred device for high-current applications such as motor drives, power conversion, and battery protection, especially suitable for system designs with strict requirements on temperature rise and efficiency.

VDS=30V: Suitable for 5V/12V/24V systems, providing ample peak voltage margin, reducing avalanche breakdown risk.
VGS=±20V: Compatible with 1.8V~12V logic levels, can be directly connected to MCU/PMIC, eliminating level-shifting circuits.
Vth=1.5V (Typical): Ensures full conduction region entry under low-voltage drive, especially suitable for battery voltage decay scenarios.
RDS(on)=7mΩ @ VGS=10V: Ultra-low on-resistance minimizes conduction losses at full load, significantly reducing device temperature rise, simplifying thermal design.
ID=70A: Strong continuous current capability to handle surge currents and steady-state demands of high-power loads.
Package TO252: Standard DPAK package with short thermal path and low thermal resistance, suitable for medium-to-high power PCB layouts, compatible with mainstream SMT processes.
Domain and module applications：
Low-Voltage High-Current Motor Drives: Extremely low on-resistance reduces winding drive losses, excellent PWM switching characteristics, significantly lower controller temperature rise.
DC-DC Converters and Synchronous Rectification: Replacing Schottky diodes can drastically reduce rectification losses, significantly improving heavy-load efficiency, facilitating power module miniaturization.
Battery Protection and Charge/Discharge Management: 70A high current carrying capacity meets the needs of power batteries, energy storage systems, and power tool protection boards; low on-resistance reduces self-heating.
Automotive Auxiliary Power and Load Switches: Voltage margin and wide operating temperature range suit 12V/24V automotive buses, reliably handling surge and inductive load turn-off transients.
Power Tools and Garden Machinery: High current density and low thermal resistance package adapt to frequent start-stop and overload conditions, enhancing device durability and safety.
Server/Telecom Power Hot-Swap Circuits: Low on-resistance reduces steady-state power dissipation, ensuring long-term stable operation of high-density boards.
Selection Summary: FDD6680A-VB, with its core advantages of 30V voltage rating, 70A high current, and 7mΩ ultra-low on-resistance, combined with mature TO252 package and Trench technology, achieves a balance of performance, thermal management, and cost in medium/low voltage high current switching applications. It is a cost-effective solution for motor drives, power conversion, and battery protection scenarios.
