FDMA8878-VB Product details
Back to previous pageProduct introduction：
The FDMA8878-VB is a Single N-MOSFET deeply optimized for low-voltage power switching scenarios. The Trench process balances low switching losses with high reliability, and the DFN6(2X2) package achieves an excellent balance between heat dissipation and board area. The combination of 30V voltage rating, 10A current capability, and 17mΩ on-resistance makes it an ideal cost-reduction and performance-enhancing alternative to traditional DPAK or SOP-8 packaged devices, especially suitable for high-density, high-volume applications.

VDS=30V: Suitable for 5V/12V/24V systems, providing ample margin for voltage spikes, reducing avalanche breakdown risk.
VGS=±20V: Compatible with 1.8V~12V logic levels, can be directly driven by MCU/PMIC, eliminating level-shifting circuits.
Vth=1.5V (Typical): Can enter the fully enhanced region even with low-voltage drive, especially suitable for battery voltage decay scenarios.
RDS(on)=17mΩ @ VGS=10V: Ultra-low on-resistance significantly reduces temperature rise under full load, allowing for smaller heatsink copper areas; typical value is 21mΩ at VGS=4.5V, maintaining excellent conduction performance under low-voltage drive.
ID=10A: Ample continuous current margin, capable of handling peak demands of most portable and automotive auxiliary loads.
Package DFN6(2X2): Ultra-small size, low parasitic parameters, supports high-frequency switching, while significantly saving PCB area and assembly costs.
Domain and module applications：
Portable Device Power Management: Low on-resistance improves boost/buck efficiency, extends battery life, small package enables ultra-thin designs.
Battery Protection Modules: Fast response ensures microsecond-level shutdown during overcurrent/short circuit, low on-resistance reduces self-heating of the protection board.
Low-Voltage Motor Drive: Low PWM switching losses, smoother motor operation, significantly lower controller temperature rise.
Consumer Electronics Control Modules: Logic-level direct drive simplifies peripherals, suitable for high-volume, low-cost products like smart sockets and USB switches.
LED Lighting Driver: Low conduction voltage drop reduces constant current source power loss, supports multiple parallel channels, improving overall luminaire efficacy.
DC-DC Converters: Replaces Schottky diodes in synchronous rectification, improving heavy-load efficiency by 2-3%, aiding module miniaturization.
Automotive Auxiliary Power Supplies: Voltage margin and wide operating temperature range suit 12V automotive bus, high reliability.
Selection Summary: The FDMA8878-VB achieves a balance between performance margin, package size, and system cost. It is a high-performance, cost-effective general-purpose choice for 30V low-voltage switching applications, particularly suitable for projects with strict space and thermal requirements.
