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 directly connect to MCU/PMIC, eliminating level-shifting circuits.
Vth=1.7V (Typical): Allows full conduction region entry even with low-voltage drive, especially suitable for battery voltage decay scenarios.
RDS(on)=3mΩ @ VGS=4.5V / 2mΩ @ VGS=10V: Ultra-low on-resistance, extremely low temperature rise at full load, significantly reduces required copper area for heat dissipation, improving system efficiency.
ID=70A: Ample continuous current margin to handle motor startup, transient power load impacts, and high-current supply demands.
Package DFN8(3X3): Dual thermal pad design, low thermal resistance, low parasitic inductance, supports high-frequency switching, while saving PCB area and assembly cost.
Domain and module applications：
High-Power DC-DC Converter: Replaces Schottky in synchronous rectification; 2mΩ on-resistance significantly improves heavy-load efficiency, suitable for server power modules.
Battery Protection and BMS: 70A high current capability meets power battery pack charge/discharge management; low internal resistance reduces protection board self-heating; supports millisecond-level fast shutdown.
Low-Voltage Motor Drive: Low PWM switching loss, smoother motor commutation, significantly reduced controller temperature rise, suitable for power tools, drones, and other loads.
Automotive Power Supply and 12V System: 30V voltage margin adapts to automotive bus transients; wide temperature range ensures high reliability; suitable for automotive DC-DC, LED driver, etc.
Power OR-ing and Load Switch: Ultra-low conduction voltage drop reduces system loss; high current capability supports multi-channel parallel redundancy design, improving power supply stability.
High-Density Power Module: DFN8 miniaturized package combined with low thermal resistance enables greater power output within a limited size, facilitating adapter miniaturization. Selection Summary: DMT31M8LFVW-13-VB achieves a high degree of unity between ultra-low on-resistance, high current carrying capacity, and compact packaging. It is a cost-effective core device for 30V low-voltage, high-power switching applications, especially suitable for projects with strict requirements on efficiency, temperature rise, and space.
