FDMC8884-F126-VB Product details
Back to previous pageProduct introduction：
FDMC8884-F126-VB is a Single N-MOSFET deeply optimized for low-voltage, high-current power switching scenarios. The Trench process balances low switching losses with high reliability, and the DFN8(3X3) package achieves a good balance between heat dissipation capability and board area. The combination of 30V withstand voltage, 30A current carrying capacity, and 13mΩ on-resistance makes it an ideal high-density alternative to traditional DPAK or SOP-8 packaged devices, especially suitable for high-current, highly compact applications.

VDS=30V: Suitable for 5V/12V/24V systems, providing sufficient voltage spike margin and reducing avalanche breakdown risk.
VGS=±20V: Compatible with 1.8V~12V logic levels, can be directly connected to MCU/PMIC, eliminating the need for level-shifting circuits.
Vth=1.7V (Typical): Can enter the fully enhanced region even with low gate drive voltage, particularly suitable for battery voltage decay scenarios.
RDS(on)=13mΩ @ VGS=10V: Ultra-low on-resistance, significantly reduces full-load temperature rise, allowing for reduced heat sink copper area; only 19mΩ at VGS=4.5V, suitable for low-voltage logic drive.
ID=30A: Ample continuous current margin to handle peak demands of high-power loads such as motors and power supplies.
Package DFN8(3X3): Small size, low parasitic parameters, supports high-frequency switching, saves PCB area and optimizes thermal path.
Domain and module applications：
DC-DC Converters: Replaces Schottky diodes in synchronous rectification; ultra-low on-resistance significantly improves heavy-load efficiency, facilitating module miniaturization.
Battery Protection Modules: Fast switching response ensures microsecond-level shutdown during overcurrent/short circuit; low internal resistance reduces self-heating of the protection board.
Low-Voltage Motor Drives: Low PWM switching losses result in smoother motor operation and significantly lower controller temperature rise.
Portable Device Power Management: Low internal resistance boosts boost/buck conversion efficiency, extending battery life; small DFN8 package aids ultra-thin design.
Consumer Electronics Control Modules: Direct logic level drive simplifies peripheral circuitry, suitable for high-volume, low-cost products like smart sockets and USB switches.
LED Lighting Drivers: Low conduction voltage drop reduces constant current source power consumption, supports multi-channel parallel connection, improving overall luminaire efficacy.
Automotive Auxiliary Power Supplies: Voltage margin and wide operating temperature range suit 12V automotive bus systems, offering high reliability.
Selection Summary: The FDMC8884-F126-VB achieves a balance between low on-resistance, high current capability, package size, and system cost. It is a cost-effective, versatile choice for 30V low-voltage, high-power switching applications, particularly suitable for projects with strict requirements on space, heat dissipation, and efficiency.
