VDS=100V: Suitable for 24V/36V/48V/60V systems, providing ample margin for bus voltage spikes and transient overvoltages, enhancing system avalanche ruggedness.
VGS=±20V: Compatible with 4.5V~12V drive voltages, flexibly matching standard gate driver ICs, MCUs, and PMICs, simplifying driver circuit design.
Vth=1.4V (typical): Low and consistent threshold voltage ensures effective turn-on even under low-voltage drive conditions, supporting a wide operating voltage range.
RDS(on)=11.6mΩ @ VGS=10V: Ultra-low on-resistance significantly reduces full-load conduction loss; combined with the excellent thermal path of the LFPAK56 package, it effectively suppresses temperature rise.
RDS(on)=13.92mΩ @ VGS=4.5V: Maintains low on-impedance even at low drive voltages, suitable for battery-powered or logic-level driven applications.
ID=69A: Robust continuous current capability, easily handles high-current surges such as motor stall and power supply hot-swap, with ample surge margin.
Package LFPAK56: Small footprint, low parasitic inductance, supports high-frequency switching; features an excellent bottom-side cooling structure, reducing required PCB copper area and system thermal resistance.
