MGSF3455XT1-VB Product details
Back to previous pageProduct introduction：
MGSF3455XT1-VB is a Single N-MOS deeply optimized for low-voltage power switching scenarios. The Trench process balances low switching loss with high reliability, and the SOT23-6 package strikes a balance between heat dissipation and board area. The combination of 30V withstand voltage, 6A current carrying capacity, and 26mΩ on-resistance makes it an ideal cost-reduction incremental option for replacing traditional DPAK or SOP-8 packaged devices, especially suitable for high-density, high-volume applications.

VDS=30V: Suitable for 5V/12V/24V systems, providing sufficient voltage spike margin to reduce avalanche breakdown risk.
VGS=±20V: Compatible with 1.8V~12V logic levels, can directly connect to MCU/PMIC, eliminating level shift circuits.
Vth=1.7V (Typical): Can enter the fully enhanced region even with low-voltage drive, especially suitable for battery voltage decay scenarios.
RDS(on)=27mΩ @ VGS=4.5V / 26mΩ @ VGS=10V: Ultra-low on-resistance, significantly reduces temperature rise at full load, can reduce heat sink copper area.
ID=6A: Ample continuous current margin, can handle peak demands of most portable and automotive auxiliary loads.
Package SOT23-6: Small size, low parasitic parameters, supports high-frequency switching, saves PCB area and assembly costs.
