AON6884-VB Product details
Back to previous pageProduct introduction：
The AON6884-VB is a Dual-N+N MOSFET deeply optimized for low-voltage, high-power switching applications. Utilizing Trench technology, it balances low conduction losses with high switching speed. The DFN8(5X6)-B package achieves a good balance between thermal performance and board area. The combination of 40V withstand voltage, 60A continuous current capability, and an ultra-low 5.5mΩ on-resistance makes it an ideal choice for high-current applications such as server power supplies, motor drives, and battery protection, especially for systems with stringent requirements on heat dissipation and power density.

VDS=40V: Suitable for 12V/24V/36V systems, providing ample margin for switching spikes and enhancing system avalanche ruggedness.
VGS=±20V: Wide gate drive voltage window, compatible with 4.5V~12V logic levels, allowing flexible adaptation to MCUs, PMICs, or dedicated gate drivers.
Vth=3.1V (typical): Moderate threshold voltage for strong noise immunity, while ensuring stable turn-on with 4.5V drive.
RDS(on)=5.5mΩ @ VGS=10V: Ultra-low on-resistance minimizes full-load conduction losses, significantly reducing temperature rise and allowing for smaller heatsinks.
RDS(on)=6.5mΩ @ VGS=4.5V: Maintains very low impedance even with low-voltage drive, suitable for low-voltage, high-current scenarios driven directly by 5V logic.
ID=60A: Dual N+N architecture with current sharing provides ample continuous current margin, easily handling peak loads like motor stall or battery charge/discharge.
Package DFN8(5X6)-B: Dual-sided cooling design, low thermal resistance, supports high-density mounting, and low parasitic inductance benefits high-frequency switching applications.
Domain and module applications：
Server Power Supply Modules: Replaces multiple discrete transistors in synchronous rectification; low on-resistance improves heavy-load efficiency; dual-transistor integration simplifies PCB layout.
High-Power DC-DC Converters: 5.5mΩ on-resistance significantly reduces conduction losses, suitable for current paths above 40A, aiding module miniaturization.
Lithium Battery Protection Boards: Low voltage drop reduces self-heating on the protection board; 60A continuous current capability suits high-rate power battery packs.
BLDC Motor Drivers: Low PWM switching losses; dual N+N complementary structure facilitates building half-bridge or full-bridge topologies, significantly reducing driver temperature rise.
Automotive Auxiliary Power (12V/24V Systems): 40V withstand voltage combined with a wide safe operating area reliably handles transient overvoltages on the vehicle bus.
Power Tools and Drones: High power density package supports compact designs; Trench technology ensures stable switching performance at high frequencies.
Hot-Swap and Load Switches: Low on-resistance minimizes voltage drop across high-current paths, suitable for hot-swap control circuits in server boards and communication equipment.
Selection Summary: The AON6884-VB, with its dual N+N integrated architecture, ultra-low on-resistance, and 60A high current capability, represents a versatile, cost-effective solution in the 40V low-voltage, high-power switching domain, particularly suitable for projects with clear requirements for power density, thermal management, and system reliability.
