FDD6670AL-VB Product details
Back to previous pageProduct introduction：
FDD6670AL-VB is a Single N-MOSFET designed for low voltage, high current power switching applications. Using Trench technology, it combines ultra-low on-resistance with fast switching capability. The TO252 (DPAK) package achieves a good balance between heat dissipation performance and board space, making it suitable for medium to high power density applications. The combination of 30V withstand voltage, 85A current carrying capacity, and 4mΩ on-resistance makes it a preferred device in fields like DC power supplies, motor drives, and battery protection, especially suitable for industrial-grade and automotive-grade systems requiring low loss and high reliability.

VDS=30V: Suitable for 5V/12V/24V systems, reserves ample voltage margin for switching spikes, improving system avalanche breakdown resistance.
VGS=±20V: Compatible with 3.3V~12V logic levels, can be directly driven by MCU/PMIC, simplifying peripheral design.
Vth=1.83V (Typical): Low threshold voltage ensures the device is fully turned on under low-voltage drive conditions, adapting to battery voltage fluctuation scenarios.
RDS(on)=4mΩ @ VGS=10V: Extremely low on-resistance, significantly reduces full-load conduction losses, effectively suppresses temperature rise, allowing for reduced heatsink or copper area.
ID=85A: Ample continuous current capability, can handle harsh load conditions such as motor stall and power supply transient surges.
Package TO252: Optimized thermal pad and frame, low thermal resistance, supports high power density layout, while balancing automated assembly efficiency and cost.
