HAT2173HWS-E-VB Product details
Back to previous pageProduct introduction：
The HAT2173HWS-E-VB is a Single N-MOS carefully optimized for medium-to-high voltage power switching scenarios. The Trench process balances low conduction losses with fast switching characteristics, and the LFPAK56 package achieves an excellent balance between heat dissipation and board area. The combination of 100V withstand voltage, 69A current carrying capacity, and 11.6mΩ on-resistance makes it an ideal high-cost-performance option for replacing traditional DPAK or D2PAK devices in applications such as communication power supplies, industrial control, and automotive systems, especially suitable for high-density, high-current applications.

VDS=100V: Suitable for 24V/36V/48V/60V systems, providing ample margin for voltage spikes, significantly reducing avalanche breakdown risk.
VGS=±20V: Compatible with 4.5V~12V logic levels, can be directly connected to MCU/PMIC/H-bridge drivers, simplifying gate drive circuit design.
Vth=1.4V (Typical): Enters the fully enhanced region even with low-voltage drive, effectively supporting stable operation under battery voltage fluctuation scenarios.
RDS(on)=11.6mΩ @ VGS=10V: Ultra-low on-resistance, significantly reduces full-load temperature rise, can reduce heatsink copper area and heatsink requirements.
RDS(on)=13.92mΩ @ VGS=4.5V: Maintains low conduction loss even under logic-level drive, suitable for low-voltage control systems.
ID=69A: Ample continuous current margin to handle transient peak demands such as motor stall and power supply hot-swap.
Package LFPAK56: Low parasitic inductance and thermal resistance, supports high-frequency switching, saves PCB area and increases power density.
